摘　　要：高超声速条件下,气动光学效应的存在严重影响红外成像制导精度,已经成为新一代高超声速精确打击武器研制面临的关键技术难题之一。为解决这一技术瓶颈,需要开展适用高超声速飞行环境的超声速气膜冷却光学窗口研究,解决高超声速飞行条件下光学窗口防热和成像难题,突破现有红外成像制导武器的速度和温度限制,可为实现高超声速条件下武器对空、对地和对海高精度打击提供支撑。Under hypersonic conditions, the existence of aero-optical effects seriously affects the accuracy of infrared imaging guidance, which has become one of the key technical problems in the development of a new generation of hypersonic precision strike weapons. It is necessary to study the optical aperture with supersonic film cooling suitable for hypersonic flight environment so as to solve the thermal protection and imaging problems of optical aperture under hypersonic flight conditions and break through the speed and temperature limitations of existing infrared imaging guidance weapons. Finally, it provides support for the realization of weapons’ high-precision strike against air, ground,and sea under hypersonic conditions.
