摘要: This paper presents a explicit guidance for lift control of aeroassisted orbital vehicle. The vehicle enters the atmosphere with prescribed angle and keeps bank being 90' until exits. entry is function speed exit speed. in can be divided into two phases. In first phase descends normalized coefficient constant slightly greater than one. During ascending decreases proportionally t o increasing dimensionless height. A comparison made plane change between optimal trajectory application control. case using provides same practical scheme realization theory. not only implementable but also simple. With lifting calculate command onborad benefits from
