An Inside Look: SpinLaunch Flight Test #7
HTML-код
- Опубликовано: 17 апр 2022
- Get an exclusive behind-the-scenes look at how SpinLaunch conducts a typical flight test on our Suborbital Accelerator Launch System. Located at Spaceport America in New Mexico, the Suborbital Accelerator is a ground-based, electric-powered kinetic launch system that accelerates a 3-meter flight test vehicle thousands of miles per hour, tens of thousands of feet into the atmosphere.
Comprised of the key components needed for the Orbital Launch System, the Suborbital Accelerator is a critical stepping stone in SpinLaunch's path to orbit and providing customers with low-cost, sustainable access to space.

You guys should totally live stream these if possible.
With any new technology the is a chance things will go wrong.
If thing go wrong are they prepared to endure the adverse publicity this would bring?
@@donnairn3419 I don't think anyone took Starship's Rapid Unscheduled Disassembly's as a negative when attempting to land... everyone was aware it was in testing phase.
That would reveal too much of the failures involved in this nonsense.
Things go wrong. That's why we test. SpaceX has made that clear to the world and shows warts and all, and I think other companies should follow suit. Nothing tells you that something is ready than seeing it succeed from it's previous failures.
@@whatilearnttoday5295 Why the hate? No need to call it "nonsense". It certainly would have practical applications in a low gravity situation, like the Moon or Mars, or other...
But if it makes you feel better to diss it, you're free to.
I’d love to see footage of the projective hitting the earth. Well done guys.
(Without parachute if possible...)
...at full speed.
Me too
Shout if you come across this. 😉
@@ytrew9717 Considering the footage they've shown of the projectiles being recovered, I doubt very much that they're using parachutes.
The technology behind this, for example, the balancing system in the spin chamber, and the release system must be super precise.
Congratulations on your successful tests. I'm following with excitement.
hahaha... yeah, the "launch vehicles" will turn into shooting stars before they ever reach the 5000mph goal.
TOTAL SCAM busted by real scientists MONTHS ago....... ruclips.net/video/ibSJ_yy96iE/видео.html
They have re-invented and greatly improved the legendary medieval trebuchet. I imagine the technical people will disagree, but I’m only referring to the primary use of centrifugal force to send mass in a desired direction or location. (So spare me, please 😂) Wonderful technology, great concept!
I'm an engineer and I agree.
@@pmp1337 Thank you.
more similar to a catapult than trebuchet but yes
it's not trabuchet, it is actually lower tech, it's slingshot that kids used around the globe.
Maybe they would get better results if they used rocks :)
Good to see Napoleon Dynamite's brother has found work. Yay, Kip!
Live stream the next one please!!!!! You gals and guys rock, I’m happy to see your progress and am cheering you on to the new frontier
What happens to the counterweight when the projectile is launched? Seems like, at those speeds, it would shoot out the side from the sudden imbalance.
Great question actually
My uneducated guess would be that they’ve designed spinning mechanism’s total weight to be large enough in relation to the projectile to where the difference in sudden balance shift is within tolerence
It's an interesting idea. My concern is there looks to be considerable Gs on the projectile just launching it to 30,000ft. Low Earth orbit is around 600,000ft or 20 times that height. To put that in perspective if your height was 600,000ft then 30,000ft would be about the height of your ankle. I can't wrap my head around how humans or electronics are supposed to survive the increased forces at the higher speeds or the shock of hitting atmosphere at basically sea level during launch at the required launch speed to get to 600,000ft.
I agree, I doubt this project is actually intending to launch astronauts or anything of value into space. It is more likely that they are riding the hype of other legitimate companies and are infact hoping to develop something they can sell for military applications.
No chance this would be used for humans, and the current projectile looked like it survived an impact with the ground from 30,000ft without taking much damage. If they scaled up the entire launch system then I imagine it would be feasible to get at least most of the way to space, then they could also strap a rocket motor to the back of the projectile to carry it the rest of the way into orbit?
I think this is still a technology demonstrator. In future the projectile would have rockets fitted to complete the launch and to take it into orbit
@@sil8127 The problem for me is I don't see how rockets could survive the G forces let alone the guidance system.
I was thinking exactly the same thing…. That’s a lot of Gs
Every venture into space is exciting. Thank You.
Every venture into space is a costly boondoggle that brings our ecosystem one step closer to destruction while we look at the sparkly lights.
So close! Your literally almost there!! Only 297,360 more feet to go
Well when you say it like that..
Pretty much impossible for this to work
Gotta start somewhere
@@DantheMan1933 for starting 8 years ago and only 1/5 of the way to obtaining the speed necessary, 32 more years to go just to get the speed and that's the easy part.
IKR... The speed they will need to achieve to get a usauble payload into space exceeds the tensile strength of the materials we have. The G Forces alone will damage any satilite they try to put into space.. This will never be feasible.
This is definitely exciting. I'll keep an eye on this project for sure.
Launch a watermelon next!
This is so freaking cool. I’ve said it before, and I’ll say it again: best of luck to the teams, can’t wait to see the 100m orbital variant. This is crazy.
Yeet machine 😂📈🚀
It defies physics, this will never be a working idea.
It's cool, but it can't work on Earth where we have a thick atmosphere. This would however be a great way to send raw materials back to Earth from the Moon..
@@goemboeck it will get a projectile close to space and save fuel that’s the whole point, not to launch directly to orbit…
@@goemboeck this tech is also good for having on the moon to send stuff back home idk
@@CarrotSurvivor that I fully agree to. But by the looks of it, they try to use it on Earth to toss another one to Moon, that is bound to fail :)
I'm a huge fan of this project. It's the second thing I've invested in from them. The first was a bridge in London they sold me. Keep up the good work guys.
How did u invest
@@chvishal I got an email of a bank account from some guy who works there one day so I put some money in it.
That’s what your mom said
I love new tech or modified tech for greater purpose, we need amazing people like you to give us hope. Thank you.
Your mom gives me hope
Amazing engineering, esp the timing of the release. Still this concept seems very Wile E. Coyote to me, lol. I was looking for the Acme sticker on the side of it. What could possibly go wrong?
This would have been easier if nobody at Spinlaunch had ever studied law.
I like this. There may be some "obvious" disadvantages but there is definitely a place for this tech. And just like with everything space related, the r&d process will produce tech that will have usages elsewhere as well.
Curious how a payload would survive slamming into the air pressure wave as it breaks through the seal destroying the vacuum. A solid metal tube would surely survive quite well, but I don't see this carrying sensitive electronics with this current configuration. We'll see how they over come that challenge
Velveeta cheese wouldn't survive those G forces.
G forces would be far worse than this air pressure wave I assume
This is exactly what i was thinking, also to get something into orbit using this methodology i cant imagine how fast it would need to spin in the chamber.
There is no way in the world you could use this to launch anything living.
@@sierramikekilo6925 Depends. The Gs wouldn't be instantaneous.
Electronics aren't the issue really. Guided artillery shells like the M982 are packed with them, and go through much worse during firing
Amazing feat!
Thanks for the update
that actually looks like something we could build in our back yard.
I like the idea
What happens to the counterweight once you've released the projectile? Does the rotor become extremely unbalanced?
Exactly that's the problem and also the timing of the explosive to release the projectile.
The channel Thunderf00t made a good debunking of this. But today selling an idea is more important than making a real proof of concept.
Ok they achieved about 1100mph with the projectile but the escape velocity of earth is at least 25,020 mph but you have to be a lot faster than that because of air resistance. Then there are also much higher forces involved when you have to get at least 30-40 times faster and the release mechanism has also withstand that forces with higher precision in the release of the projectile.
@@abelgerli The system isn't designed to FULLY send payloads to space. Rockets attached to the payloads will be the ones to finish the last leg of the trajectory to space. Aerospace America and other aerospace magazines explain the philosophy of the spinlaunch system
@@glenncoco4893 The ballpark numbers are correct even in this case the international space stations orbits earth in a very low altitude and does it with 17,100mph so the numbers ere in that ball park.
They may not have realized this yet, but it's easy. Just release the counterweight at the same time as the projectile. Then for the next launch, they rebuild the facilities a mile or two away from the crater and go again!
@@SansNeural I could not agree more 🤔🙄😆
And may be put the launch site completely under ground to protect the people around in case of failure.
This is wild. I love seeing new technology as it develops and improves
This was one of the coolest things I've seen in a long time 💯👏👏👏👏 bravo!
Brabo demais rapazeada, confesso que quando li sobre a Spin Launch pela primeira vez eu fiquei totalmente embasbacado, o trabalho de vocês é fantástico e o pioneirismo no método ajuda a empurrar as fronteiras da exploração espacial à frente, muito obrigado e continuem com o excelente trabalho. Enthusiastic greetings from Brazil. Voa garaioooooooo
Tem vários "algos" de muito errado nos dados que eles passam nos vídeos. Coisas que quebrariam regras da física. Muita coisa não bate aí....
0:55 OK - projectile plus payload, then attach the counterweight. All good so far. But after projectile launch, what happens with the mass of the counterweight? Presumably it still has tremendous kinetic energy and rotational inertia, which is now unbalanced due to launch of the opposing projectile load. So....how is this managed?
I'm guessing it is released in the opposite direction.
@@dariozanze4929 Hell of a lot of kinetic energy to dissipate right quick!
@@vermontsownboy6957 They release it into a reinforced part of the vac chamber.
@@dariozanze4929 Opposite direction means shooting it into ground.....
this is freacking awsome
Love it!! Great idea
Such an innovative way to launch, I can already see several of these on the Moon to launch stuff back to earth!
Chucking moon rocks and ores from moon might work. Low gravity and a vacuum already. 5313 mph is escape velocity. 25000 mph for earth plus a thick atmosphere.
🙄🤦♂️🤦♂️🤦♂️🤡
You must have good eyesight.
That might make more sense than on earth.
How do you compensate for the projectiles weight instantly leaving the rotating mass and having the entire machine violently shake itself apart?
I've been asking this same question for awhile now with no response. Maybe it's some proprietary system so they can't really say, but I really have no idea how they can achieve this. I did hear something about a "water brake" during this video so possibly they use water to counteract the forces somehow.
My guess would be the counter weight being half the weight of the projectile with the system being able to handle the unbalance. Once the projectile leaves, the weight would shift 180 degrees to the other end of the arm but still only be half the weight of the projectile.
@@Mi-ck
At the speed quoted and guessing the radius as about 20 m (scaled from the guys in the cherry picker) they’re pulling about a 1000g on that missile.
If you’ve ever lost a balancing weight from a wheel you’ll know that even a half ounce weight can throw things right off balance. I don’t think your idea would work. Not sure what would, though🥴
My guess would be a sliding weight that gets released on the launch arm at the time of release to compensate the payload weight, and a huge braking system to stop it ASAP
The sliding counterweight can be much bigger than the projectile and thus doesn't need to move much along the arm to keep the balance, and the opposite counterweight could also move closer to the axis at the same time.
Timing needs to be perfect of course
@@robertlane6431 Let's take a look at scale. Per the SpinLaunch website: "The first generation launch system is designed to launch satellites weighing up to 200 kilograms." About 440 pounds. 440lbs + another 160 lbs for the fuselage? So, let's make a vague, uneducated assumption of ~600 lbs total weight, is going to be a lot easier to manage the counter-forces than if we were talking about 6 tons. 600 lbs rotating at 1,000g is a 600,000 pound load. 6 tons turns into a 12 million pound load.
According to patents filed by the company, a counterbalance spinning opposite the rocket gets released at the same time, preventing the tether from becoming unbalanced. I'd seen some discussion regarding the concept of using water as the counter-weight. In theory, the combination of rapid re-pressurization, and those speeds would vaporize the water almost immediately, so I doubt you'd have to worry about handling a solid 600 pound mass rapidly decelerating.
For those pondering it, the patent also states that the rocket coasts for about a minute and ignites its engines at roughly 200,000 feet. So, yes. It is intended to have a sort of "second stage" engine"
nice job guys, keep up the great work!
So far they’ve reached 1000mph and 30,000 feet. Not bad for an idea that isn’t viable in the long run. This has the look and feel of a Theranos 2.0
The amount of energy needed to go into orbit is far greater than this machine can hold
If you put this on the moon though…. why constrain the implementation on Earth only?
I doubt their plan is to have one of these on the moon. With the only task of firing rock samples back to earth?
I'm guessing their plan is to see how high they can launch with this machine the once they have maxxed out switch to rocket boosters
@@John...44... Rock samples? Why not rare metals?
@@Bob_Adkins good point. Never thought of that
This accelerator is only a testbed. the real one will be larger and faster, but the projectile will still use a motor to reach orbit- as throwing something into orbit is not possible
Fantastic to see
Amazing!
@SpinLaunch how are you going to deal with the induced angular momentum? and how are you going to deal with scalability issues?
Just ignore it and give them money! ;D
You guys should work a second stage accelerator, like a giant rail gun after it leaves. This could allow for better guidance and an extra boost. I see this system allowing for cheap raw material delivery mainly, highly valuable in its own right.
I was just thinking that.
LOL wow i love hte animation at the end and the WHIP WHIP WHIP sound effects
Now this is cool
Cool idea and even cooler seeing it actually working this well. Congratulations. :)
How do you guys handle the unbalanced load after release?
SHHHHHHH ;D
They don't. It's just a scam.
Wow this is fascinating
Wow. you guys are doing great. The projectile isn´t oscillating at all. Such an achievement
why would they include portions of the videos where experiment doesnt go as intended on a short edited youtube video? not that they've provided full stream of project from launch to touchdown.
I have tremendous doubt this will ever be a practical alternative as a first stage orbital launching platfom.
Seems impractical, imprecise, practical loads bound by tremendous g-forces, costly and difficult to maintain a high vacuum chamber, especially when scaled up.
^*100% correct- It’s pointless masturbation.
I'm guessing you're a fan of spacex
The Army might be interested.
@@spanqueluv9er if everybody had the same “can’t do” attitude as you, humanity would get very far. It takes courage to think outside the box, but that is where the greatest rewards lie.
Costly?. This one seems a lot cheaper than using rockets to launch satelite
How many G’s does that projectile feel during spin? And wouldnt you get better benefit if you just simply took that rocket to airliner and lift it to 15km mach ,85 for launch?
Based on a centrifuge diameter of 33 meters (which may be the outer diameter) and a launch speed of 1200 mph, I get a G force of 1778. So maybe around 2000 G's.
And the calculations, for good measure.
Launch velocity: 1200 mph (1931.16 kph)
32186.00 meters per minute
Chamber diameter: 33 meters
Chamber circumference: 103.67 meters
Revolutions per minute: 32186 / 103.67 = 310.47 RPM
Relative centrifugal force: (310.47/1000)^2 * 16500 * 1.118 = 1778.14 RCF (Gs)
@@eluenskybender2948 Wow... Nice work. Great math problem to work out. I just don't see this as viable for sensitive electronics or other stuff launched into space currently.. You think a Starlink satellite could withstand those G forces?
@@avflyguy I don't have any knowledge about this. But I doubt that any "ordinary" payload would be able to sustain the 20,000 G's that some claim is neccesary to get into orbit. But you could of course increase the diameter of the centrifuge, which would lower the G's. But I still think it's an interesting project, whether or not it will be succesful.
Congratulations! Keep going!
How do you ensure to deliver the payload in working condition and what kind with such huge g forces during the launch..?
i'll be interested to see this with a fully functional rocket, even if they don't actually fire it off. Would be curious as to how the rocket with different mass properties inside of it behaves and holds up.
That sounds like a good way to destroy both the rocket and the spinlaunch system. The fuels inside those rockets don’t deal with centrifugal force very kindly.
nice! I like how a yeet machine is sending stuff to space😂 keep it up!
Wish you guys all the best!!
Cool machine! and as a motion graphic geek I have to say I love the Logo at the end!
Good luck everyone!
I'm not sold on this as a viable launch model but i hope I'm wrong because it's very cool and i want to see a full sized version fly.
Who knows what this could be used for. For all we know this could be the main method used in the future to launch cargo off the moon.
...or launching astronauts off of the Moon. This scheme fits with Futurama's vision of having an amusement park up there.
They aren’t here to sell you on it.
Wonder if it could sling smart munitions?
@@jaredf6205 Exactly. Research like this often finds uses in ways not necessarily what folks think it's for.
@UgandaBeKiddingME
You personally are buying satellite launch?
Off RUclips?
Brilliant concept 👍
Awesome!!!
Excellent! I love where this is going.
How deep did the projectile burry itself into the ground on impact?
It disintegrated before hitting the ground.
@@Arcticfox7 Did you not see the vehicle when they dug it up?
@@geoffreyofmonmouth9796 That was before the vessel/projectile was beamed into another dimension.
Less than your mom.
it is going nowhere .
That's really moving! Once your projectile launches, how do you keep the centrifuge balance? It would seem you would get a nasty wobble once it's launched? Is the machine just so big it doesn't make a difference?
ruclips.net/video/jar1LTxxAeM/видео.html
Maybe there's a deadweight that moves radially outward toward where the rocket was, exactly at the moment when the rocket is released?
@@cedriceveleigh It would need to slide about 50m in about 0.00006 seconds. The arrest would have _more_ disruptive force than leaving it unbalanced.
To have a better grasp of just how fast 450 RPM is, a helicopter operates at 400-500 RPM. The concept is to have something 3 and a half times as long, spinning at the same rate, release something the weight of a satellite and chemical rocket from the tip of one of the blades and not have the system _utterly_ destroy itself instantly.
This is amazing
Fascinating. What an amazing time to live. It is the future.
Realistically it currently resembles an over-engineered piece of modern artillery. Greater launch distances with larger and more sensitive cargo and I'll be impressed 👍
We had better luck using actual artillery. Joining several 16inch guns together for a long-rifle.
This whole idea is just a money grab.
What sort of payload is going to withstand the g-forces involved?
Unfortunately the maths of mass don't scale. And thetes no way they hit 30k feet.
@@BestKiteboardingOfficial "But but but you're just being negative!!!!!" ;D
@@whatilearnttoday5295 That's just project Babylon, designed for Iraq by Gerry Bull
Well done guys, great job. Looking forward to future videos and releases.
amazing
Great video. Thank you and good luck!
At first I was highly sceptical because I overestimated the air resistance. Hearing that you made almost 10km with "only" roughly 500 m/s sounds way better than I expected!
It's a scam. Search for Thunderfoot here on RUclips and see his debunk on this "invention"
@@Lexitivium thubderfoot video is just a piece a garbage, the guy makes claim and assumption based on marketing videos, it's just plain bad, Scott Manley's video on the subject is much, much more interesting
@@RomainCavallini Nope. Thunderfoot claims nothing and just bebunks everything that defies reality. You're welcome ;-)
This is brilliance and innovation at peak
Y'all need a SpaceYeet morale/mission patch or something :)
the projectile is "ready for reuse". That's awesome.
fabulous!!!
This is so awesome!! How would you use this system to launch sensitive and delicate items or can it be done with this system? Such a cool concept. I think I’d be dumb enough to try and get in it, lol.
If the objects can't tolerate the Gs, this won't be the right launch system for them.
@@uku4171 which is 99.99% of the loads going to space unless you launch a rock.
@@leosedf your phone could probably tolerate it. Most electronics could, I would think. It's a smallsat laucher after all. And it's not like they were planning to take a big part of the market for themselves. They're not going to take Rocketlab's place or anything. Just a small alternative that will hopefully compete at cost.
@@uku4171 yeah I u derstand what you are saying but this won't work
@ian trofimov not relevant, really. Basically only SpaceX, RosCosmos, and China have vehicles that fly humans to orbit. NASA will soon be back on the list with SLS, and I think ULA will fly the Starliner.
Although I've expressed skepticism in the past, my confidence in this system grows with each test. It is an amazing piece of technology and I sincerely hope for it's success as an entirely new way to launch satellites! Can't wait for the suborbital test!
you trolling?
@@aszthrotep4632 If they can get costs down, and offer end-to-end building of hardened satellites which can withstand so many Gs for customers, I can see no reason why they can't carve a (small) niche in the small-sat launch market. Nevertheless, that market is quite oversaturated and I can easily also see them going bust. Hopeful but skeptical about their future, in other words. I was convinced that it was a massive scam maybe like a year ago, but I think if they manage to cut down on costs and cadence I think they can survive.
What if the rocket carried some fuel switched on boosters after reaching 30000 ft to reach orbit ... Fuel consumption will be much lesser. A promising technology indeed
@@AbhishekVerma-il4or why not make an extra boost with rubber bands?
It's not designed to launch satellites there too fragile, it's main advantage is being able to send alot of materials to orbit super cheap which is our main hurdle to constructing rockets in space or pretty much any other large structure
wow. Just wow!!
Awesome.
I'm amazed that the projectile can be reused after slamming into the ground at high speed. Are you planning to reuse the fairings of the orbital vehicle?
Hi Rob, Yes! We're planning on reusing the orbital vehicle aeroshells. The flight test vehicle shown in this video is the 2nd flight of that specific vehicle, and it's ready for a 3rd flight after having been successfully excavated and inspected.
@@spinlaunch6288 Cool! That's very impressive.
@@spinlaunch6288 is the orbital rocket going to be reusable, or just the aeroshells
Hello good luck with the rest of testing and what is turn around time for reusable
@@NekoAerospaceSFS There's no way the rocket could be recoverable. Mass margins are far too small.
Curious about the forces exerted on the projectile while spinning up. How can the payload survive, unless its something very homogenous like a tank of water or oxygen?
Can't, this is a BS project. Anyone with a opinion has already said it is a dumb idea. Cute though, like a looney tunes creation.
I seem to remember hearing that the G forces are such that solid state electronics will survive it, provided they are engineering correctly.
Well, very basic things will need to be sent into space. Like water. However, you would need some kind of propulsion or guidance system too, which means things that can break.
This is so cool!
hey yall came to my dive school for welders. good to see youre still going
Hey! First of all, I'm very thrilled to see where this projetc is going to end up at, but I have a request: Could you please display the data on SI units (maybe put bouth imperial and SI on screen)?
You guys are doing an amazing job, waiting to see more!
The kind of people who invest in this are frightened and disgusted by SI units. Wouldn't be good PR.
They use m/s for velocity and ft for height... why?

But yeah, SI units is a must....
@@siyun5 Feet are always used in aviation, regardless of the country. The rest of the imperial stuff tho yeah is super useless. SI is the scientific and sensical way to make measurements.

Nice idea, and great engineering. But no practical use given the G's the projectile suffers, outside of military use.
Use it to launch pedophiles
Great job.
Most awesome indeed.
What an amazing and incredible project ! Good luck guys, whith this hard work you will reach the stars ! 👍
Hey, love what you are doing.
Can you help me out with a couple of questions?
1; how do cancel the rotational momentum on release?
2; what levels of momentum/energy are released by the counterweight on launch?
3; how do you dissipate the counterweight energy?
i'm an idiot and have no idea what i'm talking about. i would have a counter counter weight on a rail at centre mass during wind up. as you release the rocket you release the counter counter weight which slides down the rail and replaces the rocket mass. Give me my noble prize!
@@NotPoodle love your idea.
That has to take place in 1-2ms
Didn't they mention a water brake? Or maybe I misheard
They won't ever answer you.. Because this is a scam. Another kkckstarter type ripoff.
@@mastermnd22 i agree.. at the very least they are currently very far away from something usable, but likely it's infeasible completely.
Satire at its best! This reminded me of the truck stop fb page that runs crazy stories about people marrying bears and a llama that knows sign language 🤟🏼
this is crazy, and cheap and better for the environment, well done 👍
congratulations !!! you've done something that almost any airplane can do, wow !!
I'd like to know what the heck happens to the counterweight when this thing is released. Now you've got to contain something that has the same momentum as the thing that has enough momentum to go into space. The recoil on the ground system must be insane. If these guys actually get this to work, it will be insanely impressive. And then there's the problem that, by definition, they can't put anything in orbit by throwing it from the ground, and there will still have to be a second stage that will have to survive this. Who had the guts to fund this?!?
Someone that doesn’t think
You have thought more about this than they have.
I believe there is still a rocket involved. They launch it a tens of thousands of meters up then start the engines. It's interesting to see if it works
@@nonethelessfirst8519 jajajajajajajajajaj
Imagine a satellite deorbiting into surface level pressure of atmosphere. Explosion. KABOOM
Wow, unreal!!!
This gonna be my science project
Once the projectile has been released why doesn't the loss of mass immediately throw the spinning arm way out of balance and cause it to destroy itself?
Probably a hydraulically shifted counter weight and/or a brake, in this video they mention a "water brake".
@@aless5207 yeah maybe 🤷♂️ the forces at play here are huge though, the amount of centrifugally generated pull on that arm when it gets up to full speed with the projectile still attached is huge that is the stored energy that will throw that thing half way to space, and then in a fraction of a second it's gone leaving that thing still spinning at full speed, that is an instantaneous and massive change in balance I don't see how anything mechanical could be made to react quick enough and precisely enough with the amount of mass that is needed to balance it again, but they obviously have it worked out, unless its all BS which wouldn't actually surprise me now to be honest 🤷♂️
@@ats-3693 If the arm and mechanism weigh 20 tons and the projectile weighs 40kg I don't think there would be enough of an imbalance that couldn't be dealt with.
@@rjk69 40 kg travelling at 500 m/s... That's 5 MJ.
@@ats-3693 I tried to brainstorm it last time I watched one of these videos... I thought perhaps they pull the counterweight in really quickly to re-balance. If you had a decent hydraulic set up I think the speed and force is achievable. Again I'm not an expert but hydraulic stuff is pretty good at this kind of thing.
The other/additional option is just to stop the arm as quickly as possible. If you had appropriate energy storage you could take the energy out of the unbalanced arm very quickly.
I don't think this demo is BS (like faked) but I also don't see how the challenges of a system like this outweigh the potential advantages and the company might be leveraging the "sustainable, electric..." marketing factor. This could piss off skeptics because they've already been given a NASA contract which implies a govt cheque... even if they are honest in their venture, any space money going to BS is taking away from other ventures. However, its not the first time NASA would have spent a lot of money for minimal return... ;)
Can someone explain how the projectile is released so precisely at that speed to get it launched up the “chimney” and what controls that release since it has to be so precise and fast
Math, lots of math.
Oooo! So cool!
I have a question for you I understand of course you have to have a counterweight to whatever the the payload weight is that your launching to keep the machines were shaking itself apart, so how do you compensate for the release of the payload package if you have a counterbalance attached to the arm of the machine is it released at the same time into some kind of a catch pit I was curious how this works
I like it... a simultaneous throw-up throw-down system.
The G force must be very high on this kind of launch so my question is what kind of payloads will this system be able to launch without destroying it. Although very cool it doesn’t seem very practical.
second stage rockets with satellites. Our hardware can definitely sustain slow acceleration to 1000gs. We were firing vacuum tube computer guidance systems long before solid state silicone.
@@ac.creations It can't even get something to orbit, even if it survives the flight. AND if it survives and somehow reaches stable orbit, it is still hundreds of times less efficient than a rocket. Bingo bango bongo, what a machine.
@@dazm901 that's not even close to the same application of force
@@alanwatts8239 it's a scaled down proof of concept. They said the big one would be 300 ft diameter. Taking away the first stage rocket and using electricity that could be made renewably is highly likely to be more energy efficient than producing chemical fuel.
@@ac.creations You don't get it, fuel efficiency goes beyond fuel consumption in one stage. The main goal of a rocket is to get payload to space, if you have a big rocket like the Falcon heavy that can take 60 tons of cargo to orbit how is this thing supposed to compete? you'd need hundreds, if not thousands of those little launches to compensate for a regular rocket launch? how are you going to catch all of them? how do you expect to haul fragile electronics when it has to go through tens of thousands of G's?
Not that it's impossibile, but in space you already have to worry about radiation, intense heat, intense cold, micrometeorites, weight, and now you're adding something else for the engineers to solve. And you'd need a ton of engineering to do that, and it's going to cost more, and more for what? A little rocket that even the Shuttle can outperform, a vehicle that was abandoned because it was too expensive compared to it's overral efficiency.
It just makes no sense, sure, it might work if you put billions of dollars into it and some decades, but it will still be outperformed.
If my company wanted to launch a system to space using your platform, what G-loading does it need to survive from the centrifugal force of the spin-up?
20k g
Honest answer: more than most things can handle.
Awesome :)
How did you end on that diameter of unit? A bigger one would get more to end speed with the same force applied?
What sort of G forces is the projectile experiencing while being spun up? I'm not sure any satellite would survive that sort of loading. I understand that this is an experimental version of the product, and that the final version will have a larger radius...but even then...has anyone crunched those loading numbers?
20,000Gs to get to orbital distance... according to fragments in a FAQ. therefore no object with sensitive electronics is going to survive
@@renaissanceman5847 Tardigrades, the most indestructible life form on the planet can only survive 16,000Gs. This machine has no practical use at all.
@@renaissanceman5847 Fuel, water, oxigen and material for 3d printing. Image 3d printer in space build what you need.
@@Wokingflop This machine is not used to get tardigrades into space.
@@JaakkoF It can't get life to space (not even extremophiles), it can't get satellites to space. So what the fuck is it for then? It's a scam!
1200 mph launch speed is less than 1/20 of what they need to get to orbit. Also, two guys lifted and installed the projectile which means it's pretty inconsequential. SpinLaunch has a long way to go and I wish them well. It seems like a reasonable and inexpensive system for getting parts for assembly into orbit.
Those solid slugs are all this thing will ever "launch."
Brilliant
upon release how to you balance the system as the payload is separated causing a major imbalance?
30,000 feet isn't bad for 1g, on the moon it would be >90,000 feet!
With no atmosphere, probably quite a bit more....
At 1/6 the acceleration of gravity, the same KE = 1/2mv^2 = PE = mgh would put it at about 6x the altitude, plus no air friction, so even higher
