I'm probably too biased to say this but it's really a great episode! I'm so curious to know what kind of a motor they will develop. They surely need some kind of integrated solution because mounting the engines as I did on the BFS is not so optimal xD (but easier to showcase). They also need some kind of redundancy in case something fails so it would make sense to have many weaks motors rather than one strong. Then you have to think about cooling and powering them and what not. Oh boy, that will be interesting!
On the picaX, is it going to use 'tiles', or is the final layer that is exposed to the atmosphere going to be sprayed on? Can PicaX work as a spray on?
let's be honest though: the space shuttle, just from an aesthetic standpoint, was one of the best looking spacecraft humans have flown and I don't think spacex will ever be able to top how amazing it looked
Yeah... personal taste is a really weird and unique thing. For me the Starship design already passed the Shuttle by a mile regarding the aesthetics. Imo the shuttle is just a bland looking airplane that happens to go to space.
Kinda sounds like he’s saying a Tesla is just another car because it has four wheels. It has heat shields and kinda shaped similar so it’s just another Space Shuttle.

You are correct that the original space shuttle design parameters changes during r&d, but you also have to understand the limitations of the computer technologies available at the time the shuttle was being developed, it has just recently been possible to do these vertical landings, SpaceX had many failures even with the advancements of the last 3 decades.
@@jerkyturkey007 They did not have as much computer time to calculate the airflow, stress and needed physical models to perform wind tunnel tests with every non-minor change. slow and expensive.
@@laprepper the Air Force redesign was all about increasing "cross range capability". Civilian cargos are typically launched to the east near the equator to take advantage of the earth's rotation to help fling the cargo into orbit. Civilian orbits don't require much cross range capability, and that's why the shuttle originally didn't have a delta wing when it was first being developed as a purely civilian design. Military recon satellites however are typically launched in South-North polar orbits. This allows them to map a greater area because the earth rotates perpendicular to their orbit. Each orbit allows them to view a new piece of territory, (again because of the earth's rotation). It also presents a problem for the shuttle delivering the payload. He can't simply deorbit and land from a polar orbit because the launch site has moved (again due to earth's rotation). So now you need to wait in repeated orbits until everything lines up in order to make it back to your launch site.... unless you have a high cross range capability. Having a high cross range theoretically allowed the shuttle to put a large hexagon type military recon sat in a polar orbit and then land again at Vandenberg within one orbit for fast mission turnaround.
Your channel is a lot of fun dude, I appreciate your video game illustration most of all because it really brought home the difficulties of landing a rocket.
flaperon is the proper name for an actual control surface on several different types of aircraft. they're a combination of flap (to lower stall speed) and aileron (pitch/roll)
I think SpaceX decided to use evaporative cooling on the Starship after Elon watched you using radiators as heatshields in this episode. Everyone knows Elon watches your content religiously!
hi from Belgium! When sailing small boats you can change the direction by changing your position on the boat thus changing the drag. It depends on the situation but you can change your speed and/or direction using this properly and it can be really useful. ps: sorry for my poor English and thanks for the video !
That's the concept I have the biggest problem with. A part of me sees the BFS fins as a source of lift rather than control. Can the fins be built strong enough and agile enough to control the re-entry? I bet future iterations of the BFS will ditch the fins in favour of a lifting body and RCS thrusters to control attitude. Whichever route they go the heat shield is going to be a significant challenge. The heat shield is a triple threat: needs to be sturdy enough to put up with re-entry, light enough to not rob the craft of all its capacity, rapidly & cheaply refurbishable.
Lenard Segnitz You don’t want any lift, that just puts a lot of stress on the vehicle when it’s coming in hot and it doesn’t need to sail around the planet to land. I assume the flappers would be folded up on initial reentry when things are really hot and then gradually deploy. The BFS should be tail heavy with the engines in the back so it should naturally point its nose up while entering the atmosphere.
That KSP segment was a really helpful visualisation for understanding what’s going on - way better than the one from the actual SpaceX presentation. Nice work.
This also isn’t really how it would look either because he had no horizontal velocity and basically fell straight back rather than re enter as you normally would. This is more like if the BFS cancelled out ALL relative horizontal velocity and fell back that way. The kerbal demonstration does a well enough job showing how the winglets work to maneuver the craft though
My only complaint about the ksp demo was that he didn’t use the aerodynamic visualization to show drag. I haven’t watched the live stream of his rocket build but I hope he used it at least once.
Space shuttle is like a wingsuit, coming in hot on a glider. The Starship is like a sky diver. controlled free fall. Spacex has proven they can make a reusable booster, but their only experience with heat shields are Cargo and Crew Dragon, and the octoweb if you count that. Not sure if theyre using the same PicaX on starship. If they are, they estimate that will be good for 10 reentries with minimal upkeep. Following Starship development really inspires me. Innovate quickly and don't fear failure. Learn from past mistakes and come out the other side better. Keep up the Great work Tim.

Just found this channel a couple of hours ago...proceeded to watch 5 videos back to back. Congratz on a new subscriber! I knew SpaceX was doing some cool things, but I really did not know the future was looking this good for space travel in general. You're doing a great job informing us in an interesting and meaningful way - please keep it up!
As a somewhat fatalistic spaceflight enthusiast, I can't help but feel increasingly anxious about the growing complexity of the Big Falcon Rocket. However, having seen the incredible advancements SpaceX have delivered in a decade, I remain confident.
I'm an aerospace engineer who's been working on the space program for decades. Also, I have religiously followed the industry through general media since I was in high school and then both general and professional industry media since I was in college. So, I know good aerospace jounalism when I see it. From what I have seen so far your work is excellent. It's the right blend of enthusiasm and technical knowledge mixed with new media savy. I'll happily recommend your site to any person who wants to have a more detailed understanding of what SpaceX is up to than is delivered by the headline news. I much hope you expand your topics to include all other manned and unmanned space system developments.
I wondered why i stopped seeing your videos in my sub box. Turns out youtube had unsubbed me from your channel! Great video! Private space flight makes me so excited for the future!
One should not forget that the Shuttle was build by the best engineers of its time - it was not a bad system. The problem is that after it flew innovations were very are (like upgrading it to be a more reusable system). As for SpaceX, we have seen that they keep developing their rockets while they are already using them, otherwise we would never have seen a reuseable Falcon 9. So while the BFR might in its early stages suffer some of the problems the Shuttle did, i'm sure they will continue to make it more and more reusable.
Yes, this exactly! The fact that they can make changes (both small and sweeping) in house and without a massive amount of governmental red-tape will be vital.
The space shuttle was a big piece of pork. Furthermore, the Shuttle's position adjacent to the SRBs and the ET made it susceptible to damage from falling insulation and less recoverable in the event of a catastrophic failure. With a "stacked" configuation, crew riding at the front, perhaps even the crew of Challenger could have been saved.
Mopskopf 42 Part of Shuttle's problem, re innovation, was that whenever somebody suggested an upgrade or improvement, there was a significant faction in congress whose attitude was that if Shuttle needed improving, then Shuttle was no good, so let's just shut down the whole program.
Which one? It was a Jack-Of-All-Trades and Master of None. Crew Transport? NELO? GeoStationary? Trans Lunar/Mars Transport? Millitary Ops? NOAA?, NASA?, Job/Program/Money Maker? (Work was deliberately spread out accross the country.)
It makes sense an near-EMPTY Starship/Booster can use air resistance to bleed off most of the velocity, but the more mass you're carrying the more air resistance you need, and of course more fuel in the end to halt the descent into a controlled landing.
I don’t think comparing it to the Space Shuttle is bad. Space shuttle was super expensive, yes, but technologically a marvel (crazy alloys, pioneering use of composites, first reusable vehicle, staged combustion, Autogenous pressurization, crew configurations with up to 70 people possible with an extra module, etc). BFS is the only thing remotely comparable, a true spiritual successor to Shuttle.
@barbara Corcoran that is true for one particular Russian engine only. The space shuttle's engine is actually one of the most advanced rocket engines ever made, and it's is entirely US designed and built. The small Russian engine can handle amazing temperatures due to a special alloy that was invented just for this engine. After the Soviet Union collapsed a few were found in a warehouse and sold to the US. They are used to this day for smaller satellite rockets. Russia didn't have much luck with the bigger engines and as a result put a bunch of small ones on bigger rockets. Those rockets then crashed because the engines could not all be controlled precisely enough in order to work together to lift the rocket stably.
Gotta say, great flying! I was sure you were going to hit the building for a moment there, but you managed to land without incident. I just hope everyone in that section wore their brown trousers to work that day.
Tim, the width of your knowledge is truly admirable. I love how you can relate different fields and also historical designs in your explanations. Keep up the great work buddy.
I love these vids. I remember when I was about 7.5yr old when I saw Man first land on the moon, that’s 50yrs ago now, it was awesome, a day off school to watch it in good ol black n white, then several months later I got to see the landing capsule a short distance from our school, in Murray Bridge, SA. While it was some of the greatest moments and things I have seen in my life, I remember when viewing the capsule, I was somewhat surprised (disappointed maybe?) that I noticed all the control switches where the old black Bakelite type, I guess I was expecting more futuristic compounds of the time and electronics, etc, but still a great achievement. Elon Rules, I love what he is doing in most areas he is working on, Tesla’s, batteries, capacitors , etc, and especially anything to do with space and rocket research. His ideas and how he has put them into action in relatively short times is totally amazing, and putting a Tesla in space orbit has to be Historically the coolest thing for anyone to try and top in my opinion, because we can!
Thanks again Tim, this was packed with goodness. All the energy and smarts you put in to boiling down a lot of information into these concise videos is SO RARE and so appreciated. Quality stuff!
I worked in the navy on A4 attack aircraft way back when. A system called "Stab Aug" was added as an afterthought during development (early 50's)because it was discovered the airframe tended to vibrate horizontally at high speeds. So a gyro was added with a hydraulic system attached to the vertically mounted control surface, which worked perfectly. This shake was so fast it manifested itself as a violent vibration when unchecked. The moral of the story is Musk can get all the speed response he needs for his spacecraft through hydraulics, without the need for electric motors.Except to drive the hydraulic pumps of course.
Actually they did 'back of a napkin' tests with having an refilled external tank in orbit. Once the shuttle was in orbit, hook up to a new tank and away we go. The math works... the details might be a tiny bit more complex..
Probably not enough atmosphere for it to have landed on mars. I so wish our space program was working on mars the same way apollo tried to get us to the moon, back then. Our world could be so different now.
ShelburneCountry) What launch vehicle would have been able to lift a full ET other than the shuttle stack itself? I feel like they would’ve had to design a whole new launcher just to loft the tank lol
biggBOSS1991 The plan was to have one of the shuttles 'not' jettison it's ET and instead bring it along for the ride. Once in orbit, they would disconnect and leave it in orbit. Subsequent launches would refill the tank and voila.
Take a look at sailboat self steering gear, which uses the water going past to amplify the wind vane movement enough to turn the rudder. Maybe the BFS can use the air going past to provide at least some of the force to turn the airbrakes.
The BFS is based on a similar original premise as the shuttle, but it has the benefit of years more experience and better technology to make it a unique and different vessel
My biggest question is how do they cover the hinges of the aero brakes with Pica-X? Obviously nothing other than the heat shielding can be exposed but the actual hinge can’t be made from pica-x. So do they overlap sections that move? If so then how do they seal between them? Do they instead design the shape of the body to deflect heat around the hinge, creating a low pressure area to keep the heat low? Is there some other solution instead?
im kind of worried they are making it more complex than it has to.. Elon saying much of the changes were becouse he didnt like the look of the 2017 model kind of gives me backflashes to the Model X problems. To much new tech in one project just for the sake of theatrics.
Well since it is practicly bellyflopping in to the atmosphere i dont think the mechanisms will be far inside the slipstream. also more complexity in the heatshield just adds vulnerability.
@sweinberger yes of course it can work but it just ads to the complexity. And complexity drove up the shuttles cost. One key succes factors of the F9 B5 is the posibility of fast turnaround due to few and simple inspections and that driving down the cost.
They are not flaperons because flaps are design to increase lift. Ailerons are design as lift surfaces that pitch to produce roll control. These are control surfaces but they produce no life so they are more like Airbrakerons
"BFR kind of looks like the Planet Express ship from Futurama" Me: "I like were this is going" "But it looks more like the TWA Moonliner at Disneyland." Me: "Bitchin"
Basically, any craft flying people through space could be a “space shuttle”, the BFR to me looks like it could be classified as the shuttle done right. However, as you said the mechanics of re-entry and landing are completely different. Just the general design has similarities. Using large surface areas to scrub off speed during re-entry just works, plus it requires zero fuel to accomplish. The shuttles main engines only managed to scrub about 1% of the speed off (thanks to a highly intelligent everyday astronaut guy for that info) and the body did the rest, just as the Apollo missions used the capsules entering bottom first to do so. So far the BFR seems to be evolving to take lessons learned from the F9 landings and previous space mission to evolve a craft that will be the most capable space craft ever designed.
Just got back after visiting my dad in L.A. We went to the California Science Center to see the Endeavor Shuttle up close and personal. I was fortunate enough to also see it "in flight" atop a big Boeing as it did a fly by over Moffett Field near my work in Los Altos, CA. Was super exciting. Anyway, I didn't know that every single tile on the shuttle is individually serialized until I saw the shuttle up close. That kinda' threw me for a loop. I took a picture (okay LOTS of pictures) of the underside of the shuttle, which captures every single tile's individual serial number. Many of them also have little arrows for specific orientation as well. They also have one of the big orange fuel tanks outside. I was a little disappointed that you couldn't walk through it to really appreciate the size of the thing. Crazy big. Oh, and an SR-71 Blackbird out front -- which is probably my favorite aircraft of all time because of its high tech missile defense system: GO REALLY FAST!!!
Your videos are very well thought out. One minor criticism is the like many RUclipsrs you frame yourself too low in the image. Your head shouldn’t be dead center. Thank you.
can we call these "control surfaces" rather than "wings"? I think the terminology would better describe their purpose (and provide less cringe-factor :P)
I propose the term "finbrakes". As Tim says, they work like airbrakes. The word fin is rather inevitable from their appearance. I agree, absolutely not wings, they don't have that cross section or function.
I'm probably too biased to say this but it's really a great episode! I'm so curious to know what kind of a motor they will develop.

Pretty sure it's designed after futurama's spaceship lol
Thought the exact same thing here. I'm pretty sure Elon enjoys some good ol' futurama
The engine on that ship kept the ship still and moved the universe around it, if memory serves. If Space X designs that, that'd be amazing!!
Just found this channel a couple of hours ago...proceeded to watch 5 videos back to back. Congratz on a new subscriber!
I knew SpaceX was doing some cool things, but I really did not know the future was looking this good for space travel in general.
You're doing a great job informing us in an interesting and meaningful way - please keep it up!
I just subscribed, thanks!
Same here! Love this guys videos!
As a somewhat fatalistic spaceflight enthusiast, I can't help but feel increasingly anxious about the growing complexity of the Big Falcon Rocket. However, having seen the incredible advancements SpaceX have delivered in a decade, I remain confident.
I can't wait to see that giant thing that is almost as big as an A380 descent and land on it's fins...ummm I mean air brakes.
Hans Yolo you’re a star citizen fan?
Unfortunately yes I am. Scamjokes inc?
I can't wait to see something bigger than the shuttle take off without a dirty great external tank and two massive SRBs but still make orbit.
Hans Yolo your a scam Hans.
Green screen and illusions can make wonders ....
I have only paid real attention to space travel the past month and in that time your channel has become my new past time. it's great
I'm an aerospace engineer who's been working on the space program for decades. Also, I have religiously followed the industry through general media since I was in high school and then both general and professional industry media since I was in college. So, I know good aerospace jounalism when I see it. From what I have seen so far your work is excellent. It's the right blend of enthusiasm and technical knowledge mixed with new media savy.
I'll happily recommend your site to any person who wants to have a more detailed understanding of what SpaceX is up to than is delivered by the headline news. I much hope you expand your topics to include all other manned and unmanned space system developments.
"I'M A FALCON 9!" I died.
No you are still alive if you are able to post that joke
I wondered why i stopped seeing your videos in my sub box. Turns out youtube had unsubbed me from your channel! Great video! Private space flight makes me so excited for the future!
Funny, I read your comment and realized the same had happened to me...
That "Bring-Your-Spacediver-To-Work-Day" landing was SUCH a great one that I'm going to go ahead and believe it was your first and only. Awesome!
If PICA-X had hay fever, would that make it PICA-CHOO?
One should not forget that the Shuttle was build by the best engineers of its time - it was not a bad system. The problem is that after it flew innovations were very are (like upgrading it to be a more reusable system). As for SpaceX, we have seen that they keep developing their rockets while they are already using them, otherwise we would never have seen a reuseable Falcon 9. So while the BFR might in its early stages suffer some of the problems the Shuttle did, i'm sure they will continue to make it more and more reusable.
Yes, this exactly! The fact that they can make changes (both small and sweeping) in house and without a massive amount of governmental red-tape will be vital.
For a ship that killed 14 astronauts, not bad.
Imagine what it would have been in bureaucrats hadn't been involved?
The space shuttle was a big piece of pork. Furthermore, the Shuttle's position adjacent to the SRBs and the ET made it susceptible to damage from falling insulation and less recoverable in the event of a catastrophic failure. With a "stacked" configuation, crew riding at the front, perhaps even the crew of Challenger could have been saved.
Agreed, the critical failure list that would result in a lost orbiter was astounding.
Mopskopf 42 Part of Shuttle's problem, re innovation, was that whenever somebody suggested an upgrade or improvement, there was a significant faction in congress whose attitude was that if Shuttle needed improving, then Shuttle was no good, so let's just shut down the whole program.
The BFS is going to be what the Space Shuttle SHOULD! have been but never was.
Forty five years of technical advance will do that for you.
The AGS is going to be what the BFS SHOULD! have been, but never was.
Which one? It was a Jack-Of-All-Trades and Master of None. Crew Transport? NELO? GeoStationary? Trans Lunar/Mars Transport? Millitary Ops? NOAA?, NASA?, Job/Program/Money Maker? (Work was deliberately spread out accross the country.)
It makes sense an near-EMPTY Starship/Booster can use air resistance to bleed off most of the velocity, but the more mass you're carrying the more air resistance you need, and of course more fuel in the end to halt the descent into a controlled landing.
“We parked it by the processing facility”
The Research Lab technician who saw the spacecraft outside his window: “Um...”
I love the little 3D animations!
Kerbal Space Program? It's a PC 'game'...
I don’t think comparing it to the Space Shuttle is bad. Space shuttle was super expensive, yes, but technologically a marvel (crazy alloys, pioneering use of composites, first reusable vehicle, staged combustion, Autogenous pressurization, crew configurations with up to 70 people possible with an extra module, etc). BFS is the only thing remotely comparable, a true spiritual successor to Shuttle.
^ this
Hopefully the BFS will be more than a glorified space taxi and do more than just go up to LEO and back.
@barbara Corcoran that is true for one particular Russian engine only. The space shuttle's engine is actually one of the most advanced rocket engines ever made, and it's is entirely US designed and built. The small Russian engine can handle amazing temperatures due to a special alloy that was invented just for this engine. After the Soviet Union collapsed a few were found in a warehouse and sold to the US. They are used to this day for smaller satellite rockets. Russia didn't have much luck with the bigger engines and as a result put a bunch of small ones on bigger rockets. Those rockets then crashed because the engines could not all be controlled precisely enough in order to work together to lift the rocket stably.
I love hearing you talk about this not knowing that you're talking about yourself!
Gotta say, great flying! I was sure you were going to hit the building for a moment there, but you managed to land without incident. I just hope everyone in that section wore their brown trousers to work that day.
Tim, the width of your knowledge is truly admirable. I love how you can relate different fields and also historical designs in your explanations. Keep up the great work buddy.
Tim, I need to be awake for work in 5 hours! Why would you do this to me?!
Well then you are supposed to wake up right about now.
Next time put it in the watch-later queue, and simply view that when you come home the next day.
things have changed so much in 18 months. the basics of the starship are the same but the details are vastly different now. great video!
I love these vids. I remember when I was about 7.5yr old when I saw Man first land on the moon, that’s 50yrs ago now, it was awesome, a day off school to watch it in good ol black n white, then several months later I got to see the landing capsule a short distance from our school, in Murray Bridge, SA. While it was some of the greatest moments and things I have seen in my life, I remember when viewing the capsule, I was somewhat surprised (disappointed maybe?) that I noticed all the control switches where the old black Bakelite type, I guess I was expecting more futuristic compounds of the time and electronics, etc, but still a great achievement.
Elon Rules, I love what he is doing in most areas he is working on, Tesla’s, batteries, capacitors , etc, and especially anything to do with space and rocket research.
His ideas and how he has put them into action in relatively short times is totally amazing, and putting a Tesla in space orbit has to be Historically the coolest thing for anyone to try and top in my opinion, because we can!
Those pop in animations were sweet. Just wanted to say that
Thanks again Tim, this was packed with goodness. All the energy and smarts you put in to boiling down a lot of information into these concise videos is SO RARE and so appreciated. Quality stuff!
Who's here after Sn10?
I worked in the navy on A4 attack aircraft way back when. A system called "Stab Aug" was added as an afterthought during development (early 50's)because it was discovered the airframe tended to vibrate horizontally at high speeds.
So a gyro was added with a hydraulic system attached to the vertically mounted control surface, which worked perfectly.
This shake was so fast it manifested itself as a violent vibration when unchecked.
The moral of the story is Musk can get all the speed response he needs for his spacecraft through hydraulics, without the need for electric motors.Except to drive the hydraulic pumps of course.
This episode was super informative. Great work on this one!
"Control surfaces" would be a better description than "air breaks"
changing orientation by changing drag: a Paraglider does.
"give me a lever long enough and I can lift the world" a smart guy!
God spaceship 2 is terrifying to watch fly, but keep hounding elon for that interview lol
The BFS is just a new space shuttle,... in the same way an F-22 is just a P-51 Mustang. Great vid, thanks.
Rc Zagadka no it isnt
Why would anyone dislike science videos 🤔
Entertainment and educational. Kudos space nerd👍👍
Tim: Just let the fins *(!!!AIRBRAKES!!!)* maintain our orientation 😂 AMAZING explanation by the way, this video is so helpful and informative!😎😀
Well you can't fly to mars with the space shuttle...
Actually they did 'back of a napkin' tests with having an refilled external tank in orbit. Once the shuttle was in orbit, hook up to a new tank and away we go. The math works... the details might be a tiny bit more complex..
Probably not enough atmosphere for it to have landed on mars. I so wish our space program was working on mars the same way apollo tried to get us to the moon, back then. Our world could be so different now.
ShelburneCountry) What launch vehicle would have been able to lift a full ET other than the shuttle stack itself? I feel like they would’ve had to design a whole new launcher just to loft the tank lol
biggBOSS1991
The plan was to have one of the shuttles 'not' jettison it's ET and instead bring it along for the ride. Once in orbit, they would disconnect and leave it in orbit. Subsequent launches would refill the tank and voila.
Or can you
Greetings from Germany and big thanks for your videos! You still make me believe in a good future!
Ok I'm so burnt and just realized this video was 2 years old
OH MY GOD IT TOTALLY LOOKS LIKE THE SPACE SHIP FROM FUTURAMA THANK YOU FOR POINTING THAT OUT!!!!
I'm so exited for any foottage of an actual real BFR!
Take a look at sailboat self steering gear, which uses the water going past to amplify the wind vane movement enough to turn the rudder. Maybe the BFS can use the air going past to provide at least some of the force to turn the airbrakes.
18:06 It has to be said:... Tintin's rocket ALSO uses the fins as landing legs! ;-)
Great video nonetheless!
When I look at the BFS my mind goes to Tintin. Not joking
The BFS is based on a similar original premise as the shuttle, but it has the benefit of years more experience and better technology to make it a unique and different vessel
My biggest question is how do they cover the hinges of the aero brakes with Pica-X?
Obviously nothing other than the heat shielding can be exposed but the actual hinge can’t be made from pica-x. So do they overlap sections that move? If so then how do they seal between them? Do they instead design the shape of the body to deflect heat around the hinge, creating a low pressure area to keep the heat low? Is there some other solution instead?
im kind of worried they are making it more complex than it has to.. Elon saying much of the changes were becouse he didnt like the look of the 2017 model kind of gives me backflashes to the Model X problems. To much new tech in one project just for the sake of theatrics.
I was wondering about that too.
Well since it is practicly bellyflopping in to the atmosphere i dont think the mechanisms will be far inside the slipstream. also more complexity in the heatshield just adds vulnerability.
Maybe if less than one milimeter is exposed to the heat, the heat will dissipate itself?
@sweinberger yes of course it can work but it just ads to the complexity. And complexity drove up the shuttles cost. One key succes factors of the F9 B5 is the posibility of fast turnaround due to few and simple inspections and that driving down the cost.
I would call them “flaps”or even “flaperons”.
airbrake + flap + elevator + airleron -> brakeflapetoron
Or Winglets?
They are not flaperons because flaps are design to increase lift. Ailerons are design as lift surfaces that pitch to produce roll control. These are control surfaces but they produce no life so they are more like Airbrakerons
I like the term flapelators
Brakerons
If you had landed that right at the front door, I would have sent you an internet cookie. Awesome flying though. Loved this episode.
Geez, I have to say, that retro starship (or should I say bfs) with 3 flaps and that carbon composite Hull really looks sci-fi
This is some amazing stuff tim
"BFR kind of looks like the Planet Express ship from Futurama"
Me: "I like were this is going"
"But it looks more like the TWA Moonliner at Disneyland."
Me: "Bitchin"
"It moves space *around* the ship!"
Please cure me from this addiction of space and this channel
They should name the first bfr “falling with style”
I feel like 'skyfall' would be better :)
You know a space rocket company is innovative if it's rocket design puts most of the KSP-made rockets to shame.
THIS!
deadass
Basically, any craft flying people through space could be a “space shuttle”, the BFR to me looks like it could be classified as the shuttle done right. However, as you said the mechanics of re-entry and landing are completely different. Just the general design has similarities. Using large surface areas to scrub off speed during re-entry just works, plus it requires zero fuel to accomplish. The shuttles main engines only managed to scrub about 1% of the speed off (thanks to a highly intelligent everyday astronaut guy for that info) and the body did the rest, just as the Apollo missions used the capsules entering bottom first to do so. So far the BFR seems to be evolving to take lessons learned from the F9 landings and previous space mission to evolve a craft that will be the most capable space craft ever designed.
Came here to learn about Starship. Actually watched a KSP let's play! :D
This guy's improvement is skyrocketing.
I want to see an episode about rocket fuels and what properties they have , and rocket boosters and engines and how they work .
Alexandru Costache he already has a vid
4:00 If I recall correctly, there are 2 more planes that used airbrakes like that: the Horton 229 and the P61 Blackwiddow. But correct me if I'm wrong
Horten 229 never left the blueprint stage.
@@Jupiter__001_ Actually 3 prototypes were made, 2 of them flew and there is one left, which now rests at the Smithsonian Museum
^^^
I’m glad somebody is being more critical of this new design.
Congrats, a rare youtube video that ages well. Yup it's electric control motors.
Yeah, he was right about the Tesla electric motors.
Who else thinks its funny that the sci fi spaceships from the 1960s looks like the modern day BFR
Elon has actually said that was by design!
It's now July 2019, and they indeed made a little hop!
Just got back after visiting my dad in L.A. We went to the California Science Center to see the Endeavor Shuttle up close and personal. I was fortunate enough to also see it "in flight" atop a big Boeing as it did a fly by over Moffett Field near my work in Los Altos, CA. Was super exciting. Anyway, I didn't know that every single tile on the shuttle is individually serialized until I saw the shuttle up close. That kinda' threw me for a loop. I took a picture (okay LOTS of pictures) of the underside of the shuttle, which captures every single tile's individual serial number. Many of them also have little arrows for specific orientation as well.
They also have one of the big orange fuel tanks outside. I was a little disappointed that you couldn't walk through it to really appreciate the size of the thing. Crazy big. Oh, and an SR-71 Blackbird out front -- which is probably my favorite aircraft of all time because of its high tech missile defense system: GO REALLY FAST!!!
:D Your face after you spell out PICA is perfect and priceless
Not like a missile into the ground, yes, electric motor from Tesla Roadster to handle torque @ nearly 7400 lb-ft.
one question! it is as important as the entire mission itself! do we have a hot flight attendant?
Your videos are very well thought out. One minor criticism is the like many RUclipsrs you frame yourself too low in the image. Your head shouldn’t be dead center. Thank you.
Everyone chilling in the office, look out the window, there is a rocket landing in the parking lot
can we call these "control surfaces" rather than "wings"? I think the terminology would better describe their purpose (and provide less cringe-factor :P)
I propose the term "finbrakes". As Tim says, they work like airbrakes. The word fin is rather inevitable from their appearance. I agree, absolutely not wings, they don't have that cross section or function.
I have a better idea of what to call it. Lets call it what it really is. A complete joke,fake! Idiots.
AND AEROPLANE PLZ FFS
No they're wings😜
@@gwenvandeveer8558 You're weird.
wow i like the new channel logo
Scott Manley will always be my #1 source for accurate info, but you are improving. Good job.
Spectacular! Fins? Airbrakes? Who cares? I learned a lot!
