Research on Side Window Cover Throwing Technology for Reentry Vehicle
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.
