| Abstract: | Gas dynamic resonance ignition technique was used in design of hydrogen/oxygen small thrust rocket engine. By means of analysis of special impulse and combustion gas temperature in different mixture rate,system parameters of hydrogen/oxygen small thrust rocket engine were determined. Ignition tests of gas dynamic resonance igniter,hot firing tests of hydrogen/oxygen small thrust rocket engine and impulse ignition tests were carried out in different thrust operation conditions. It can be confirmed from the h... |
