摘要
高超声速滑翔飞行器具有高机动和远程快速到达能力,是高超声速技术应用的前沿领域。快速准确地预测飞行器表面受热变化特征,对高超声速滑翔飞行器热防护系统设计十分重要。以基于锥导乘波构型的高超声速滑翔飞行器和跳跃飞行弹道为研究对象,对其表面不同特征区域的加热开展了快速预测方法研究;采用选用方法分析驻点辐射平衡温度随飞行弹道的变化规律;在弹道特征位置上针对飞行器前缘及上、下表面的加热情况进行分析,获得高超声速滑翔飞行器受热的整体特征,可为分区域选择热防护措施提供参考。
Hypersonic glide vehicle ( HGV) is the frontal application field of hypersonic technology with the ability of high automotive and rapid-reach of long range. How to predict the characteristics of aerodynamic heating changing on the surface fleetly and accurately is very important for the thermal protection system ( TPS) of HGV. This paper took a HGV with conically derived waverider and skip-glide trajectory as the research object,studied a quick-predict methods for HGV on different regions. Based on this met...
