概述由于飞机的高速飞行,机载导弹发动机壳体外部受气动力加热。导弹发射后,主装药燃烧产生的燃气从内部对壳体进一步加热。壳体的温度升高,会导致材料的机械强度下降。为考核空空导弹发动机在受气动力加热条件下工作的安全性,必须进行空空导弹发动机气动加热模拟试验。 Overview Due to the high-speed flight of the aircraft, the exterior of the onboard missile engine shell is aerodynamically heated. After the launch of the missile, the gas generated by the combustion of the main charge further heats the housing from the inside. Increasing the temperature of the shell will result in a decrease in the mechanical strength of the material. To test the safety of air-to-air missile engines under aerodynamic heating conditions, air-to-air missile engine aerodynamic heating simulation tests must be conducted.
