Guidance technology for autolanding of unpowered reusable launch vehicle
摘要
Abstract
The autolanding phase is the last phase of Reusable Launch Vehicle(RLV) flight mission. This unpowered flight phase begins at AutoLanding Interface(ALI) that is typically at a 3 000 m altitude, and ends at touchdown on the runway. A method is introduced to obtain the attack angle command used as one of the guidance commands by utilizing its relationship with overload command in the working frequency domain. Considering the range limitations of single trajectory guidance method, the concept of multi-trajectory guidance is introduced. The simulation results show that it can make Reusable Launch Vehicle realize a safe landing with a wider range of initial longitudinal distance deviation and improve the capacity of the existing guidance scheme.关键词
