- Abstract
After more than 50 years of development, China's Long March Launch Vehicles have the ability of launching payload to various orbits, such as LEO, GEO, SSO, LTO, etc. However, all of the launch vehicles are disposable at present. Reutilization of the launch vehicle is a very important technical route for reducing costs and implementing large-scale space exploration. In recent years, all of the world's major space powers are exploring the technical route of reusable launch vehicle. This paper reviews on the history and the development status of reusable launch vehicle, and analyzes technical schemes of some typical reusable launch vehicles, including the booster of Space Shuttle, the first sub-stage of Ares-1, the booster of Ariane 5, K-1, DC-X, Falcon-9R, the first sub-stage of Baikal, Adeline. And superiority of the three typical types of launch vehicle stage recovery, such as parachute landing, propulsive landing and aerocapture landing, are discussed, on the aspects of technical difficulty, technical risk, economics, influence on launch capacity. And then, the applying condition of each recovery scheme is also discussed. Moreover, the challenge and feasibility of actualizing reutilization for China's Long March Launch Vehicles are analyzed, and proposes the development thought based on China's economy and technology ability.
