英文简介
Long March 12A/Changzheng 12A (LM-12A/CZ-12A) is a reusable orbital launch vehicle developed by the Shanghai Academy of Spaceflight Technology (SAST) of the state-owned China Aerospace Science and Technology Corporation (CASC). The rocket is based on the Long March 12, but extensively re-designed for first stage re-usability, and use of gas generator cycle methane/liquid oxygen powered rocket engines in both stages. The first stage uses 7 Longyun-70 engines designed and manufactured by the private company Jiuzhou Yunjian (JZYJ), while the second stage uses 1 YF-209V engine from CASC's Academy of Aerospace Liquid Propulsion Technology (AALPT). On launch missions where the first stage is recovered, it will land on a down-range landing pad located in Minqin County, Gansu Province.
