This was a short duration design/build/test project that I did to evaluate a confined combustion reaction control thruster idea that I had been thinking about for a few years. I designed the thruster for single discharge combustion using a burst disk and pre-charged fuel oxidizer in the chamber. I triggered ignition using a custom high current bridge-wire igniter. I fired the thruster dozens of times using a matrix of different fuels. I tested the thruster in a vacuum chamber with different ambient pressure to evaluate nozzle geometry under different conditions.
