| Abstract: | In order to develop the fault diagnosis technology for liquid propellant rocket engine based on exhaust plume UV VIS radiation,the experimental study is conducted on the UV VIS radiation of the exhaust plume of tripropellant model engine and the kerosene oxygen flame,which is utilized to simulate the combustion of kersene oxygen propellant engine.The radiative transfer model is used to the theoretical calculation of the spectra for the measured one.The "inverse" of the simulation is conducted by evolutionary computation.These research show that this technology is feasible and significant. |
