As a mechanical engineer myself, I'd personally like to see how the projectile release mechanisms work in their current testing configuration. Spinlaunch marketing is suspiciously quiet about this area and for good reason. Knowing how the conservation of angular momentum works, a projectile released from a rotational path will be tumbling end-over-end at the same RPM as the spin arm itself. It's impossible to avoid this problem without significant deviations from the original design goals (particularly launch RPM and payload mass) which defeats the whole purpose of the project. Early marketing material straight-up broke the laws of physics and early test launches on the 1/3rd scale launcher confirmed that tumbling was a major problem. And there is no amount of R&D that can fix it.

It's great to see this work that will expand SpinLaunch opportunities.

@xandergreer

that is awesome, cant wait to see one of these in space one day

@Technichian462

There must have been a lot of small scale tests. Tests that started in a home environment, a garage? I'd like to see all of them.

@faraday9234

The problem you can't solve is putting people in it. BUT, highly useful for satellites which is clearly stated as their market.

The reaction wheel isn't powered on in this video. It looks like they are just hand spinning the wheel, especially since the motor isn't plugged in

@juliankandlhofer7553

fascinating! although, since you're probably staying in low earth orbit for now with this launch system, I would guess a solid state system like magnetorquers for attitude conroll would be more reliable that a mechanical system of gyros that you have to deploy, right?

@RWBHere

He was almost inaudible because of the foreground music.

@Grayday117

Why not just have the wheel upright and spin it like a Ferris wheel? Then, depending on when you let go of the satellite, you could potentially launch it at any degree. This seems like a better solution. It would mitigate the bending issue as well as stabilize the created centrifugal force…

@NormReitzel

Do you dump the angular momentum of the projectile into the atmosphere at release?  That's an additional drag term, no?

@hafizuddinmohdlowhim8426

This technology is not scalable but very interesting

@4olovik

It would be ok to send materials for 3d printers into space this way.

@alan-wj5yo

Great effort

@anjulakumarisaha6884

Please make a spin launch model for science project.  Please 🙏

“Some people think you have to modify satellites to use them in our accelerator. This is not true. Now let me tell you about how satellites have to be modified to work in our accelerator.”

@bob15479

I feel like this engineer is selling his soul.

@EugenePutin

This seems like a scam

@Oivaras

Hah, this scam is still going? It won't work, it can't work, you've got nothing.

@harbifm766766

big scam
