摘　　要：采用光谱诊断技术中的相对强度法测定了单元推进剂六硝基六氮杂异伍兹烷 (HNIW)在 3MPa和5MPa两种压力下的燃烧火焰温度分布。结果表明 ,相对强度法能准确地测出单元推进剂HNIW在整个燃烧过程的温度分布曲线 ,测得的最高燃烧火焰温度低于相应压力下的理论计算温度 ;测量压力升高 ,最高燃烧火焰温度更接近于理论计算温度。此实验结果说明 :在较高压力条件下 。The combustion flame temperature distribution in the axes are measured by relative intensity method of the spectroscopic diagnostic technology for monopropellant hexanitrohexaazaisowurtzitane (HNIW) at 3 MPa and 5 MPa pressure, respectively. The investigation results show that the curves of combustion flame temperature distribution in all combustion course are accurately measured by relative intensity method for monopropellant HNIW. The measured highest combustion flame temperature in the axes are lower than theoretical combustion temperature at the same pressure, and are more close to theoretical combustion temperature along with the rising of the pressure. The experimental results indicate that the combustion flame temperature distribution can be measured by the relative intensity method for high energetic and high burning rate propellant at higher pressure.
