摘要
为发展基于羽流 UV - VIS辐射光谱的液体火箭发动机故障诊断技术 ,以光谱采集系统为测量手段 ,对三组元模型发动机排气羽流及用以模拟煤油 -氧发动机燃烧的气氧 -煤油火焰的近紫外与可见光谱辐射进行了实验研究 ,利用辐射传递模型对实验结果进行了理论计算 ,利用演化算法对实验结果进行了反算。
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.
