Also, a rocket that hangs doesn’t need near the structural beef as one that is designed to withstand landing on its feet.

Also, a rocket that hangs doesn’t need near the structural beef as one that is designed to withstand landing on its feet.
- askvictor 2y agoNot convinced about this argument; wouldn't the forces during the slow-down burn be applied much the same as the from the feet?
- ars 2y agoActually no - the forces travel inside the "tank" of the rocket, and push against the top of it. The force doesn't push against the nozzle of the engine.
- slow_typist 2y agoSame pressure in the tank as in the nozzle? That doesn’t sound right. It would burst.
- ben_w 2y agoSame force, not same pressure. The nozzles are relatively small. I wouldn't want to try to intuit what the force distribution would be and how much is carried through each component of the structure, though — that's what simulations are for.
- krisoft 2y ago> The force doesn't push against the nozzle of the engine. I’m not sure what you are saying here. The force pushes against the nozzle, (and of course the walls of the combustion chamber.) That is the purpose of the rocket engine, to push the rocket forward. They are not just there to provide mood-lights.
- ars 2y agoI said "nozzle", as in the side walls of the engine. The force doesn't transfer via those walls, rather it goes through the full tank of the rocket and pushes against the top.
- krisoft 2y ago> I said "nozzle", as in the side walls of the engine. Ok? I seem to have said the same. > The force doesn't transfer via those walls Where do you think the force starts on a rocket? What pushes the rocket forward?
- HPsquared 2y agoThe chopsticks on the tower can absorb a lot of the impact, I'd guess.
