Plus, because this rocket is so small, to remain competitive, it can only cost a small fraction of the cost of a bigger conventional rocket. Taken together, these things are already super-hard to achieve, not even mentioning the challenge of constructing the 2 km/s slingshot itself.

Ok, so keep in mind conservation of momentum. With the radius of the spinner as R, the projectile will travel 2pi*R distance from release in the same time as it takes the spinner to make one full rotation after release. Because of conservation of momentum, the projectile will keep rotating (tumbling in this case) at the same angular velocity as the spinner at release. That means that after traveling just pi*R/2 distance, the projectile will have rotated through 90 degrees to be completely sideways. And since it probably won’t have exited the vacuum chamber by then, it won’t have had any aerodynamic forces to help stabilize by then. Although this tumbling is a real problem, the demonstrator seemed to fly mostly straight, so I wonder if you have a secret method to cancel out the rotation on release.

All it takes is to release the nose of the rocket before the tail is released. The delay is on the order of (length of the rocket)/(its velocity), times a coefficient on the order of unity, the exact value of which depends on the details of mass distribution of the projectile and on where the attachment points are. So, for a 5 meter long rocket going at 2 km/s, the nose will be released about 2 ms before the tail. The tether continuing to pull on the tail after the nose is released, in these 2 ms imparts the 450 rpm of angular velocity and zeros the angular velocity of the projectile.

@cogoid

2 жыл бұрын

Engineering necessary to harden the payload is relatively straightforward -- moving parts need to be locked down for the launch, other parts need to be stiffened. Overall it is surprisingly not an issue -- military electronics and mechanics exist that function at several times higher accelerations (any electronics in the artillery shells, electronics in bombs designed to pierce many meters of concrete before exploding, etc.) Hardening for surviving high acceleration comes with a weight penalty, but not a huge one. The necessity of designing the entire rocket to withstand such g-forces is a different matter. Normally, the rocket structures are built as light as possible, with a very small safety factor over the actual loads that they will experience in flight. This is very necessary, because the velocity achievable by the rocket is proportional to the logarithm of the initial mass to the final mass -- unless the structure is very light, the velocity is too low for reaching the orbit. Designing the entire rocket for 10000g comes at a heavy cost to performance. The 10000g acceleration would produce pressures in the rocket tanks up to 1000 bar, requiring much heavier tanks. Spinlaunch claims that their rocket will be _"so simple it can be mass produced cheaply"_, but this would need to be demonstrated to be believable. For example, Rocket Lab launches up to 300 kg into the orbit using a 12 ton rocket launching from the ground. Spinlaunch will have to use a similar weight catapulted rocket to launch a similar payload. Considering that the rocket will have to be built to withstand huge acceleration and also the hypersonic flight through the lower atmosphere it is far from obvious that it can be made cheaper than the same size rocket that does not experience such harsh conditions in flight. And that is without even considering the cost of the centrifuge itself! It may be technically possible to launch rockets this way. But it is hard to see how this can be more economical than today's rockets. And if tomorrow fully reusable rockets bring the launch cost further down, the situation will become even more complicated.

@@cogoid "Relatively straightforward", that's a stretch ! We currently build and test spacecraft sub-systems to withstand a quasi-static acceleration of around 20g. This launch concept can only work with small, ruggedized cube-sats and never with fully fledged medium to heavy telecommunication satellites (which are around 3 to 8 tons for sizes of 2 to 6 meters). And, of course, we already clamp down every deployable parts at multiple points. You compare it to artillery ammunitions, but those only need to survive huge shocks for mere milliseconds (not seconds or minutes), which can be mitigated with dampers/potting. The batteries are made of molten salt (thermal batteries) which resists to shocks but only provide power for minutes (duration of a typical ballistic trajectory flight) and can't be recharged. Those are two different worlds with totally different approach of engineering. Of course, there can be cross-seeding for some parts of the launcher itself as the requirements are usually different than for the payload (I used thermal batteries on the 1st stage of Ariane 6 as the duration is small and lithium-ion batteries cost an arm and a leg when made for such application).

@@corentinnaisse5350 You make good points. At sizes above a few meters (in the direction of acceleration) no material can support even its own weight at 10000g. Only relatively small assemblies are feasible. I think SpinLaunch hopes to be able to ruggedize small satellites rather larger than a cubesat. Their goal seems to be to create small communication satellites similar to those used by OneWeb, and small Earth observation satellites like SkySats. Judging from their publications, they are, for example, working on ruggedized reaction wheels for such applications.

this is a great idea but it need lot to work on if they deal with all the problems then definitely it is going to be our future there will be lot's application of this . so good luck 🤞 !!

Fingers crossed 🤞 for success. Great idea 🙂

Thunderf00t already busted this spinning Hyperloop thing. Looks great at the first but has a lot of isues is you do the math and the physiks. A capsule returning from space had around mach 20 and reaches tempratures around 1700° in nearly vacuum. And they try to lounch a Rocket whit mach 7 at seelevel whit 100% atmosphere. This thing will melt down in the second it touches the air. Maybee it could be something for the Moon or MAYBEE Mars but nothing for a planet whit atmosphere on it. I would highly recoment to watch his video: @

You accomplished absolutely nothing and it is physically impossible to achieve what you're trying to achieve the way you're doing it. But I've only been an engineer for 28 years, I'm sure you've got some dreamers that figure they can defeat physics lol. It didn't even come out straight lol and you don't have a perfect vacuum, and good luck getting that thing spinning fast enough, the amount of energy required is astronomical. This is just a scam lol

But I'm sure people that believe the hyperloop is possible also think that you can make a super duper trebuchet to fling things into orbit, because feelings yo lol

Congratulations. Keep it up!!!

I’ll remember this channel when it becomes popular

Amazing & beautifuly simple.......but I will have to learn more about how it releases the vehicle? The timing is incredible!

Good Technology !! Hope it will be a success 🔥

This is simply amazing

this is frikin awesome

I heard NASA is going to give this a shot with an official cooperation now. Would be so awesome to see this actually working out in the end!!

It’s only a small grant

Good luck! Great idea!

I’ll try spinning, that’s a good trick!

Throwing things into space makes so much more sense. Storing the energy required into the vehicle kinetically, is orders of magnitude more efficient than doing it chemically. Be it this system or some other eventual mass driver that achieves it, I am sure the tech will happen one day.

Can't wait to ride in the hyperloop on the way to the spinlaunch after drinking my Juicero squeezed breakfast.

It’s a cool and consistent concept but a huge problem would be the extra space debris.

This video clearly shows that engineering has no boundaries

nice and quick way to get critical hardware and small tools and stuff to space stations, items that can handel the G

Spinning accelerators are underrated.

Incredible handle on physics. Congrats!

It will work. Congratulations all engineers

Brilliant!

Freaking Cool video and concept!

You could probably use the spin launch to constantly ferry goods from the moon to Earth orbit. Hmm, a space station that has a spin launch while in orbit around the moon. Remember spin launch is used to create enough momentum to exit Earth with rocket thrust capabilities. on the moon, you could probably send payloads straight from its surface to Mars too. Food, water, entertainment. So now there is a space elevator to build on the moon to also carry resources from a lunar orbit from a geostationary orbit around the moon. The concept is quite stable because luckily the Earth's moon is what is called a tidally locked moon. It's about the moon's rotation around it's poles axis. you always see the same side of the moon from Earth.

It won't work in orbit on a space station, the movement will create momentum and will make the space station spinning itself.

This would definitely work 🖤

That’s amazing!

I love this, it's so cool! I really wish you best of luck. Would be possible to have a projectile on both ends, or maybe even have the launcher in "+" shape for four? I assume loading multiple projectiles (like bullets from a magazine) isn't possible due to extreme forces. But it looks like too much "effort" to release just one of them :-)

Unlikely but I'm not sure. You're dealing with extreme level forces here so you have to have a counterweight or else the arm would rip itself apart when the projectile is released.

AMazing!!!!!

To anyone wondering, it WILL work. We usually think of crazy stuff and think it's the future. But we are stuck on the 1980's minds, where these things were the future. To make things simple, the future is now, and we should support private companies such as SpinLaunch, because national agencies are still stuck in the 80's, and they can not afford to fail and develope revolutionary projects because of the super tight budgets that they get.

On Earth, the movement to be more sustainable in all things is in full swing. We’ve seen the stratospheric rise of the electric car. We’ve started using renewable forms of energy to power everything from traffic lights to entire cities. In space, the same ideology holds true for SpinLaunch. The innovative design that SpinLaunch has developed drastically cuts the fuel demand needed to launch the rocket, and thereby the consumption of a non-renewable energy source.

EPIC!!

This system could work. It would launch the vehicle through the thickest part of the atmosphere and save considerable propellent over a conventional rocket. The limiting factor may be, as someone mentioned, the considerable g forces exerted in the centrifuge.

The moment I saw picture of it, wrote it off because of the centrifugal force, all other things aside. A 500kg satellite would weight 10,188 tons @ 853rpm. Force = m v^2 / r ... satellite mass: 500kg ... radius: 25m ... tangential velocity: 2235.2 m/s ... angular velocity = 853.8rpm ... force 99,922,381 newtons ... centrifugal acceleration: 199,845m/s^2 ... earth gravity is 9.807 m/s^2. So we got 20377x the gravity of earth exerted on the satellite. Meaning a 500kg satellite would weight 10,188 tons at the end of the arm/claw that will holding the satellite before release. How did these guys manage to build this thing, this far, without looking at the basics of math? How did every single one of them miss this?

The fabric that separates the vacuum from atmosphere (and rocket punches through) is pretty sci-fi too.. where sea floor atmo pressure is 10.3 tons/square meter and we got an circular opening of ~2.4 diameter that the fabric covers. So we got 4.52m^2 x 10.3 tons = That is some cool fabric that can handle 46 tones of pressure but the rocket still can punch through! Just sell the fabric, get super rich!

pure genius!

The Olympians would be proud.

I admire your courage to think differently❤
