球锥形罩体热力耦合试验方法研究

摘要

This paper introduces a new thermal-dynamic coupled test method for spherical cone radome in high Temperature and supersonic jet flow field produced by rocket motor. Aerodynamic force of jet flow is insufficient to simulate transverse aerodynamic force of the radome at large angles of attack and maneuver flight trajectory, so the thermal-dynamic coupled test facility is designed. Test results show that thermal-dynamic coupled test is feasible in high temperature and supersonic jet flow field, the test method can be used for following test.%本试验方法是在燃气流试验设备产生的高温超声速自由射流流场热环境中，针对燃气流施加的力载荷模拟量不足的情况，设计了一套外力加载装置模拟大攻角变轨机动飞行时所承受的横向气动力，解决了本试验装置在高温环境下的力载荷模拟问题，并成功进行了球锥形罩体的热力耦合试验，本文内容对于类似的高温热力耦合试验具有重要的参考价值。
