    Compressed Air Reverse Thruster

    Thank you! I'm glad you understood what I was saying - I was starting to think I was going crazy. I had figured it had a lot to do with specific impulse but I didn't know how to make the math work. I was also off on the math for momentum - we're actually looking at more like 500kNs, which I...

    Compressed Air Reverse Thruster

    Have you ever seen what happens when the valve stem of a compressed air bottle is sheared off? My question boils down to what are the physics of that reaction? My hypothesis is that if I can replicate that effect (preferably with a nozzle and a valve rather than simply shearing the stem), and...

    Compressed Air Reverse Thruster

    Hey there, a couple things: I'm an architecture student. This has nothing to do with my curriculum. I'm self teaching for a hypothetical problem. For the purposes of this, consider me a hobbyist - It has nothing to do with homework. The parameters are 'wishy-washy', because the problem is...

    Compressed Air Reverse Thruster

    Hello everyone, 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...
