If it dipped into the atmosphere temporarily on an elliptical orbit, could the air gathered be stored for a long flight? Then maybe get more fuel from another planet's atmosphere or moon for the return trip?
My knowledge suggests when gasses are heated rapidly, they also expand due to the new energy in the gas.
Is it possible to create a thruster that is able to lift 10kg via electric heating?
The thruster would allow cold air to enter the chamber, where it would then be super-heated & ejected as...
First off, I want to apologize if this thread is in the wrong place but I am new this. Anyway, so I recently checked on the VASIMR plasma engine since I was interested in it. But one thing I didn't understand about it is if it ejects the neutral gas it uses. What I mean is that it obviously...
I'm attempting to determine the impulse that can be generated by expelling compressed air from a pressure vessel stored aboard a moving craft through nozzles in the nose of the craft. The vessel has a forward momentum of roughly 2,000,000 Ns.
EDIT: For semantics sake, consider...
i need to design a light weight platform(capable of carrying 60-100kg weight) with some kind of thrusters so that it can go down smoothly through air from about 5-10m of height to ground level. can any one tell me what kind of thrusters i should use??
