[Temperature distribution measurement of high energetic monopropellant by spectroscopic diagnostic technology].
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.
