摘　　要：为提升再入飞行器在复杂电磁干扰条件下的高精度打击能力,提出一种适用于雷达/红外双模复合制导模式的整体式红外侧窗抛罩技术方案。通过地面试验和仿真分析,验证了红外窗口热密封结构的可靠性和抛罩方案设计的合理性,并获取了在高马赫数、大动压条件下红外玻璃保护罩抛出后的运动轨迹和姿态。试验结果表明:红外窗口热密封性能良好,能够有效防止外部热流进入飞行器内部。抛罩时保护罩可被顺利抛出,保护罩与弹体分离后能够顺利飞出激波影响区,并始终朝着远离弹体的方向运动,不会与弹体发生碰撞。抛罩后红外光学玻璃无破碎,能够确保红外导引头通光视场无污染。该项研究成果可为再入飞行器抛罩技术的发展提供技术支撑。In order to achieve the purpose of precision strike of reentry vehicle under complex electromagnetic interference conditions,a side window cover throwing technology for radar/infrared dual-model combined guidance is proposed.Through simulated analysis and ground tests,the rationality of heat seal structure of infrared window and the reliability of cover throwing scheme is verified,and the motion track and flight attitude of cover are obtained under high-Mach and high dynamic pressure conditions.The results show that the heat sealing performance of infrared window is effective,which can prevent the external heat flow into the interior of the vehicle successfully.The cover can be thrown successfully when it's needed,the cover can fly out the shock wave-affected zone and always move away from the vehicle continuously,which can not crash the vehicle.The infrared glass is in good condition,which is not broken and polluted.The research provides a technical support for the investigation on cover throwing technology for reentry vehicle.
