基于TDLAS的固体推进剂装药羽流流速测量方法
Measurement Method of Plume Velocity for Solid Propellant Charge Based on TDLAS
摘要
Abstract
A new method based on tunable diode laser absorption spectroscopy(TDLAS) was introduced to measure the plume velocity of solid propellant charge, which was achieved by selecting one absorption line near 1392nm of the major combustion product-H2O through frequency calibration, cross arrangement of optical path, and using the Doppler frequency shift effect. In the static state test, the characteristic curves of the plume velocity and the pressure curve in the combustion chamber were compared, the feasibility of the technique for the measurement of the plume velocity of solid propellant was verified. A compact measurement prototype was developed, which is powered by lithium battery, the response time is 30ms, the mass is 2kg, the power consumption is less than 5W, the velocity is measured online and the result is stored.The dynamic test flight on the rocket sled was carried out,and the available results of plume velocity were obtained.The results show that TDLAS can be used to measure the dynamic plume velocity and it is an effective process for obtaining the online combustion parameters.关键词
