SpaceX inspired edf rocket part 2: Final assembly, tuning and maiden flight
HTML-код
- Опубликовано: 21 ноя 2024
- This is the second part of my Spacex inspired edf rocket project where I assemble the final pieces of the rocket, tune the correct PID values and perform a maiden flight.
In order to find the correct PID values i had to build a rig that suspends the rocket in it's center of gravity and which allows for 2 degrees of freedom. I first tried to tune the PID values with the rocket suspended on a wire but this ended up working not so great like you can see in the video.
Once i got the right PID values dialed in, I first did like 10 hover tests inside (now i did try this out with the wire attached) before going outside to attempt a maiden flight. I build and painted the landing platform a day before the maiden flight and the paint was still a bit sticky. As a result of this the rocket stuck to the landing platform and tipped over. For the next attempt i put some baby powder on the platform to prevent it from sticking (which gave me some nice clouds when taking off ;-)
It turns out landing an orbital rocket booster (RC replica) isn't that easy.Cudos to you mr. Elon Musk ;-) I wanted to do some more test flights to try to stick the landing but unfortunatley the wind started picking up. However I'm still very happy with the results i managed to get out of it (in contradiction to what some people tought ;-)
Once the weather clears out again i will definitely try the landing bit again, I'm even thinking of adding a gps to the pixhawk flight computer and attempt an autonomous landing. We'll see.
For those of you who say an edf is not a rocket, you're right it's technically a single copter design in the shape of a (SpaceX) rocket. An edf really is the easiest and cheapest way to control the thrust to maintain a stable hover.
I wished i had the technology, knowledge and money to attempt to build a liquid fueled one.
I'm referring to "Spacex inspired" because i did use some general proportions from the falcon 9 rocket but had to make a lot of adjustments to turn it into a fully capable working rocket that's capable of hovering.

Wow that looks awsome and you've got it flying so well! Great work Brian
Thank you very much Tom! I’m a big fan of your channel. 😁👍
Omg tom stanton
I want a baseball canon
Too bad, rockets dont have propulsion in vacuum and these space agencies are faking it all.
@@idontcare7961 shut up flat earther
Great job! FYI I found that iNav was much easier to tune than Arducopter for this sort of thing. I was never able to get my single copter flying well with Ardupilot but iNav was very stable with just a few minutes of tuning.
@rctestflight thanks man, I’ll definitely take a look at iNav, thanks for the tip. Btw i also love you channel, I watched a lot of your videos. You made me want to build a solar plane so bad haha 😂👍
Alexey chekurkov , with your skill in engineering and design you could probably build this guys anti gravity device. Many people have elvaluted his videos and cannot prove them fake. His videos are in Russian but some have transportation and full explanation of theory.
I am seriously impressed! Not only by the result so far but also by your structured approach. Great job!
I remember when you first started this lol. It’s really cool. I’d recommend putting motors on the side near the top for added stability. Not sure how big of a job that would be coding wise, but it would definitely help for keeping it stable and help during landing.
No words !! Awesome !!!!
Un piacere vederti qua
That's actually amazing! The legs design is beautiful. Waiting for more updates.
Damn you are so smart!! Hats off to you man!! Keep doing what your doing we need more brilliant minds like you nowadays!! It would be so cool to see it fly around like a rocket or sidewinder missle then land please do somthing like this in next video!! Well done man!!
You are a great inventive constructor with passion and commitment. Don't give up, you'll be great. I'm cheering for you.
HELLO BRO SAW YOUR CHANNEL FOR: [A LITTLE OF EVERYTHING], IT'S A LATIN CHANNEL, I LIKE IT, IT IS VERY ENTERTAINING TO SEE HOW YOU BUILD, YOU DO VERY INTERESTING THINGS, WHAT A GOOD VIBRA, GREETINGS FROM COLOMBIA...✌🏻
I see a future SpaceXer, great job Brian, I was impressed with the gimbal mounted test stand, the rocket blew me away!
This is absolutely amazing! I've been working on a EDF VTVL vehicle too and really respect your work knowing how challenging this is! The fully functional legs are so satifying! It would be cool if you add some deployable fins on V2 so it can fly up and simulate landing
Great project!! Looks great!
Add weigh to the lower position or move down the EDF or battery.
I fly RC airplane and when the plane is in hover and nose heavy start to oscillate the same way that your booster, so my advice is to add more wight in the lower position or remove weight from the upper position.
Good luck!!
It looks a lot like SpaceX when they were first trying to land a booster. A lot of falling over... They had a lot more explosion. lol. Looks great!
You made the world a million times better with this dude, thank you
he's in the shop again marlene, playin with those damn rockets again!
Well I really appreciate spacex's struggle seeing your landing struggle with much simpler approach where forces involved are in small scale.
*AMAZING WORK* Thumb up i am just for long time in RC Model Scene but that i have never see befor, very very nice.
Looking great from my rc perspective too, Great thing is you can dial it in, with almost infinate adjustment.
Landing geat needs some attention, id temporrly do a rc helecopters trainer style landing gear, till its set up.
You are talented enough to be inducted in to NASA/Space-X team. Good work and Good Luck.
1. Put a rocket engine at bottom. 2. Put landing legs at top of first stage. 3. After burn launch, eject capsule (parachute?) and use small gyro to flip first stage of rocket 180 degrees. 4. Now with landing legs down, use the landing motor to put her down. Piece of cake!
Very creative and she looks beautiful. Excellent work!
This is awesome Brian - great job. I wished we had found this before our attempted EDF Rocket build video we just posted. We are wanting to get rid of our parachute and go to a VTOL solution in our version 2 so this fantastic to see it's possible. Love your projects
please youtube make this guy famous to inspire next gen engineers
Thanks man, appreciated 😊
Your wish has been granted, totally random bell notification for this vid, now subbed
Who is this? Why did I get a bell notification? Oh, never mind. This is some cool af stuff.
Same here 😊
excellent video, i really like the little test stand you built. looked very clean and professional.
Thanks Travis, nice to hear 😉👍
Just popped up on recommended videos. I'm not and RC Rocket guy but that was awesome, congrats on the project 😎👍
Thanks man 😁
Never give up is the key for success. Keep climbing. 🚀🚀
I come here from un poco de todo,keep it up bro
Excellent effort and design .Nice work humanity reference.
Genius !!!!!!!!! If it were easy everyone would make it,
It take a special mind and fortitude.
Well done Bravo 💪😎
Nice work! All those landing look so like space x in real life!!
Ooo I didn't knew you were going to make this thing fly, epic!
Well if the youtube thing doesn't pan out you have a bright future in engineering!
Am i the only one who doesnt know anything about this yet i watch it because i find it entertaining?
this is what i want to do in my spare time.
Atlast my favourite video for which I was waiting for is out here 😎😎 thankx sir, you are an inspiration for young aerospace engineers 🙏🙏
Please check, the center of mass over and it's ratio over length. Great work Brian keep it up
Awesome work Brian! Really love the design!
Thank you Marko!
Omg I loved the ending trial and errors. Very cool.
Just like with the real thing, I was thinking "This will never work at all".
And just like with the real thing... I was wrong. :D
Nice work!
Keep going, you're almost there! Maybe griffins or engines for lateral thrust
Haha yes, unfortunately grid fins aren't that usefull at low speeds, but using compressed air thrusters might work to keep the rocket upright during landing.
Very impressive!
I like that you run to try to catch it every time it falls...but never get there in time :D
I didn't catch it once haha😅. I stood a bit further because I didn't want to ruin the shot 😁
I just gave up on trying to catch it in the end haha, almost all parts are snapfit and can be pushed back after a crash, i just had to replace one leg servo arm once.
Ahahaha. I could "see" the resulting explosion when it toppled. Nice work in making this!
Wow!! Huge Respect for your engineering!!
Brilliant, well done. It took Spacex a few attempts before they got it right.
Vooreerst PROFICIAT voor deze prestatie.
Ik had eerlijk een beetje mijn twijfels of hij zou vliegen, hopelijk is ze nog in zijn geheel om volgende maand eens een indoor demo te geven. ( ? 18/10 )
Landen is nog altijd het moeilijkste maneuver
Haha merci Walter. Om eerlijk te zijn begon ik ook te twijfelen of hij wel zou vliegen 😅 Ik had in het begin veel problemen om de juiste PID parameters te vinden maar heb deze na het bouwen van een gestel (dat hem vasthoud in zijn CG en 2 vrijheidsgraden van beweging heeft) uiteindelijk gevonden. Ik ga hem zeker meenemen naar indoor, dit zou geen probleem moeten zijn. De meeste onderdelen zijn snap-fit bevestigd en komen gewoon los bij ne crash. De neus is bevestigd met witte ductape en schuift er gewoon uit wanneer hij crasht. Landen is inderdaad het moeilijkste haha. het minste dat hij nog wat snelheid heeft in een bepaalde richting bij het landen valt hij omver. Daar moeten we nog iets op vinden 😉👍
When quarantine make you more productive👍
Loved this. Keep up the good work. What attention to detail and what focused effort.
@J Flow thanks man 😁
Absolutely amazing! So much fun watching the hovering falcon 👍🏼
Don't give up dude..you nearly there
Wow great work Brian!! 👏👏👏
Thanks Sergio!
i'll be honest. I expected a massive explosion when it fell on its side. This is really cool.
Wow, this is really cool man! Congratulations !!
Really good......we need more people like you.congratulations
WoW great job !!, even the vertical landing it’s hard but I’m impressed how you can fly it ...
Excellent work so far, never give up! You can do it!
Impressive!
And also makes SpaceX all the more impressive 👏👏
Love this. You are so close. I think it is top-heavy.
The weight needs to be towards the top in order to achieve a stable flight.
Echt heel mooi gedaan Brian 👍👍
Op naar de 20k abonnees 😉
Creative Electronics merci 😁👍
Awesome work bro,it's really a motivation for hard work.
When Elon musk sees this, he will give you a call right away
Really nice work... To be continued 😊
Keep up the good work ,
Very inspiring vedio . dont stop your effort till u land it .
LOVE FROM INDIA BROTHER
it may be bouncing on landing because of the flexiblility on the leg mechanism. Awesome solution for the air intake!!
Awesome! Great work Brain!
When I saw it on my recommendations, I've thought he's like Tom Stanton and here's Tom in the comment section hahahaha
Very nice.
Love this project. Looking forward to more videos
Hey Brian,
Great attempt. Almost did it!
Let’s get this man hired at space X
Magnificent work man! Huge thumbs up! Subscribed.
Thanks man 😁👍
Respect 10/10. That is epic design skills
Increíble proyecto, saludos desde Argentina 🇦🇷👍
great job...even Space X had few failures before they landed the booster successfully
Awesome stuff. Was thinking that the mass and size of the replica isn't that big, so trying to maneuver it outdoors must equivalent to having the real rocket maneuvering in a tropical storm 😋
With that in mind, very much impressive indeed.
This is awesome bro! Yes liquid is definitely expensive, but maybe u can try a mini sugar rocket? Just enough to launch like 20m since the focus is on the landing
Awesome work don't worry you will get it to work soon
Great job dude! That's Awesome, oh AND COOL FREAKING YARD!!
Very cool... A couple of possible solutions.....use the pid controller on the gear legs. Appears the problem gets much worse when the first leg gives and the others touch down. Time it so if say at 5deg rocket tilt the gear plane is -5deg the other way. At a minimum link the legs so they react/move together from impacts. Other possible solution would be lateral thrust ports just below the fan directing flow for lateral stability... Aka cold gas thrusters. Once ground contact happens vector control is zero.... took SpaceX a few tries as well!!!
Great job! I will wait for a successful landing
You have done a wonderful job with the implementation, i think you should write a code for landing too.. Make it auto and your every attempt will be successful, spacex is also doing that automatically not manually..
This is amazing work and progress! I'm wondering, watching the videos, if you're trying to do too much manually. for instance, would a downward facing camera that's looking for the 'marker' of the landing pad be something that could assist with the landing. the computer could make faster adjustments I'd think. Also do you need thrust on the head of it? The first landing came in at an angle, there was a bit of a bounce and then it looked like the head momentum just kept going (makes sense, the base was 'stuck' as it was on the pad). If there was thrust at the head, I'd think a small amount would go a long way. That may make the design too complicated, but just my thoughts. Really well shot video, thankyou! Subscribed and looking forward to the next one!
YOUR AWESOME DUDE
Now that looks awesome!!!
I was about to ask what kind of rocket engine this is. This is still an impressive feat to keep it that stable.
I think I'm watching the second part of "How Not to Land an Orbital Rocket Booster" video haha. Nice work BTW looking forward to the landing day :D
Hahaha lol the only thing missing were the huge explosions 😂😂 and thanks man👍
Cant wait to see your progress, subbed!
Amazing job! Keep making
Better than I was expecting this early.
Awesome! For this problem ( 7:15 ) you need to reduce the weight from legs, because the inertia causes the giro.
Best wishes !!
Great job ! Try to add suspensions to absorb the shock and put the F9 back in position
Wonderful work, absolutely love it!
Thanks Evert, I printed out a new set of thrust vector control fins with a chamfer just like you suggested, they work great now 😉👍
Wow! It looks pretty awesome! And it is.
Thanks for the like!
Greetings from Finland!
Interesting idea. Well done :)
Keep up the good work! Don't give up!
Great. Nice garden btw!
Haha thanks man 😉👍
great video man. already excidet for the next video keep it up😁
Looks great so far! Go on and improve it! 😝
This is brilliant, great job!
Nice attic shop!
Thanks man ;-)
Awesome job if i might add, I think you will have better landing results if you incorporated shock style landing legs, and if possible shift as much weight you can down to help out with that center of mass; I think your next job may be in Hawthorne CA, great job guy
