摘　　要：评估热防护系统(TPS)的热性能必须通过试验模拟真实再入时TPS承受的热边界条件和压力环境。文章对热防护系统再入气动热的试验边界条件进行了简单叙述,详细介绍了热真空试验设备以及温度和压力控制方法。通过典型试验件原理性试验对热防护新系统热真空试验方法进行了验证。The overall performance of thermal protection systems is evaluated by subjecting the TPS to the heating conditions and pressure environments that the system will experience during an actual re-entry. Test boundary for simulating the TPS re-entry heating is described. A description of the thermal vacuum facility and control technique for temperature and pressure is provided in detail. The thermal vacuum test technology for thermal protection system is evaluated by subjecting the insulation to a typical re-entry pressure and surface temperature.
