本文介绍了双试片法与中止多试片法测定丁羟复合推进剂侵蚀函数的结果,以及当推进剂燃速不同时、流经燃烧面燃气成份不同时对侵蚀特性的影响.试验结果表明,基本成份相同的推进剂,燃速慢的比燃速快的推进剂侵蚀严重;燃气温度高、固体微粒多比燃气温度低、固体微粒少的推进剂侵蚀严重.并将所得结果进行p-t曲线的计算,再将计算结果与试验发动机实测的p-t曲线进行比较. 对试验结果进行了初步分析.
In this paper, the results of double-plate method and discontinuous multi-plate method for determining the erosion function of butylated hydroxy compound propellants are introduced, and the effects of different gas compositions on the erosion properties when flowing through the combustion surface when the propellant burning rate is different are shown. , The same basic composition of the propellant, burning faster than the burning rate faster propellant serious erosion; gas temperature is high, the solid particles more than the gas temperature is low, less solid particles of the propellant erosion serious and the results were pt curve , Then compare the calculated result with the pt curve measured by the test engine.The preliminary analysis of the test results.
