摘　　要：X-37B轨道飞行器是世界上第一个具有可重复使用、高超声速飞行、高机动变轨及快速响应能力的空天飞行器。X-37B突破了空天飞行器热防护技术的瓶颈,成功验证了新型的轻质非烧蚀热防护技术。分析了X-37B"全球快速精确打击目标"的特殊功能对热防护系统的需求,提出了X-37B空天飞行器热防护系统的新技术———轻质、非烧蚀,最后探索了X-37B热防护新技术的实施途径。The unmanned X-37B orbit vehicle is the first reusable hypersonic aerospace vehicle in the world, featuring in hypersonic velocity, highly mobile orbit changing and rapid response capabilities. Broken through traditional TPS technology handicap, X-37B successfully demonstrates the performance of most notable thermal protection advance. Based on military commands analysis of X-37B, one kind of new type thermal protection technology lightweight and non-ablation is put forward, and furthermore, sci- entific approach of X-37B thermal protection explored.
