摘　　要：可重复使用飞行器具有成本低廉、服役准备周期短的优势,是当今航天领域的重要发展方向。防热技术是发展可重复使用飞行器的关键技术之一。在其服役周期内,防热结构会多次承受严酷的气动力、热、噪声载荷环境,极易受到损伤,影响飞行器正常工作。可重复使用飞行器所使用的隔热瓦防护结构的完整性和剩余寿命直接影响了可重复使用飞行器的重复使用性能,对防热结构进行检测评估对飞行器的服役至关重要。本论文对当前适用于隔热瓦材料的检测手段进行了总结,对比分析了各种方法的优劣,为可重复使用飞行器的热防护结构发展和应用提供技术支持。Reusable aerospace craft has advantage of low cost and requiring short prepare time,which is a hot spot in aerospace industry.The thermal protection technology is the key technology for reusable aerospace craft.During active service,the thermal protection structure of reusable aerospace craft is exposed to extreme thermal,aerodynamic force and noise environment,in which the aerospace craft is highly possible to be damaged.The integrity and residual life of thermal protection is the deciding feature for the reusability of the aerospace craft,which makes the detection on the thermal protection much more significant in the middle of active service.This article summarizes the current detection technology that can be applied to detection on thermal protection structure,comparing the advantages and disadvantages of each technology,giving technical supply to the development of reusable aerospace craft.
