复合材料推力室套筒高温工作状态地面模拟试验方法

Experiment Method on Floor Simulating Low Oxygen and High Temperature Environment of Propellant-Thruster Sleeve Made of Composite Material

通过惰性气体氛围模拟高空低密度氧含量,对飞行器末修系统复合材料推力室套筒高温下工作状态进行地面试验模拟,具体包括热-力顺序加载和热-力同时加载两种环境模拟试验方法。结果表明:地面试验达到了在不搭载高模试车的情况下对套筒承载能力和耐高温性能进行考核的目的,经飞行试验证实通过考核的套筒结构可以满足飞行工况使用要求。

A engineering method is used to simulate low oxygen and high temperature environment during altitude flight of aerocraft by inert gases all around, in which the propellant-thruster sleeve made of composite material actually works. Concretely, there are two experiment methods, loading the force and heat orderly, and loading the force and heat at the same time. The analysis result of experiment data indicates these experiments are able to examine mechanics capacity and high temperate performance of the propellant-thruster sleeve, not by actually starting up of the engine in altitude flight simulation.
