WHY .... hasn't this shown up yet ?

The ACME Satellite Launch Company!

Good luck with that. The force would break welds, screws and rivets in the vehicle. You’re actually not saving any energy; you have to pay Isaac Newton for the motion no matter what.

Reminds me somehow of Gerald Bull’s gun-launched satellite research on Barbados, during which he shot test projectiles out of a cannon and into space. They didn’t enter orbit though. Not sure how topics many are in this keyword, but I know it’s at least one. :^)

While the centrifuge is up-and-running, why not share the cost among 200 “hardened” satellites, and fling them into space inititiated from an ocean-facing launch ramp?

Won’t the speed is reaches cause heat damage from air friction?

Agreed. The watermelon just exploded on impact.

I went back and looked at the gif. Her knees rose up as she rocked back. I think it was close but I don’t think her knees came up far enough, fast enough to deflect the melon. That could’ve lessened the blow. Yikes.

Depending on the mass of the thrower, natural freqeuncies, etc., could be managed.

No. 10k G’s isn’t all that uncommon. As an example, an artillery round goes down the barrel at 15k - 20k G’s with balloting loads in the 5k - 10k G’s range and setback loads in the 5k G range when the round leaves the barrel.

I’ve built and tested all kinds of electronics that survive these loads easily; moving parts too.

I’ve tested electronics up into the 100k G range. Loads like that are common on 20mm and 30mm ordinance; like the cannon on the Bradly fighting vehicle. Typically, the electronics for these types of rounds are the warhead fuze.

Basic Astrophysics says this is preposterous. What do spaceships returning to Earth use for breaks? The atmosphere. Where is the atmosphere the most dense? The ground. You will either lose all of your momentum to atmospheric friction or burn up your rocket.

Doesn’t matter if it works. They got their government grant. I’d love to know what congressman is getting the kickback.

...SpinLaunch has built the massive centrifuges to spin rockets at high speed inside a vacuum with minimal friction, hoping to launch rockets at 3,000 miles per hour....

I hate to be the bearer of bad news but escape velocity is 25,000 mph. They're 22,000 mph short.

But, hey, it's only numbers, right?

What could possibly go wrong with this concept.

A rocket and contents of an undetermined weight traveling at 5,000 MPH

Obviously will not be manned!

Not sure what kind of payload or rocket could withstand the G-force

Somehow I get the feeling of an impending Myth Busters or Three Stooges participation.

“How, exactly, is this rocket going to spin around in circles for about an hour until its speed eventually exceeds 5,000 miles per hour and not melt or fall apart from the heat?”

I saw your question was answered, but also keep in mind that the projectile/satellite only experiences frictional heating for 1 minute, far shorter than any re-entry vehicle...so just maybe they don’t get toasted...but they still have that huge g-force.

But given the g-force, if they can meet their claims, expect larger launchers, which would lower the g’s and thus allow additional (i.e., more sensitive) payloads.

“Won’t the speed is reaches cause heat damage from air friction?”

But it only sees that for 1 minute prior to the firing of the rocket thrusters at 200,000 feet. And then those thrusters only fire for another minute, and they’re well clear of the atmosphere. So all of heating is confined to, maybe, 90 seconds - which may well prevent damage.

Wouldn’t be needed on the moon.. ever see the lunar landers from Apollo take off? Such a low gravity those tiny engines were enough to get back to the orbiter.
