But the Chinese industry was not mature enough to produce such a rocket until they obtained examples (and probably documentation) of the Russian RD-120 in the early 1990.〔 Development began in the 2000s, along with its sibling, the bigger YF-100, which would power the LM-5, LM-6 and LM-7 boosters and first stages.〔〔〔 Testing was directed by the China National Space Administration (CNSA) commencing in 2005. Development works are mainly carried out by the Xi'an Aerospace Propulsion Institute. It will be used as upper stage engine for China's next generation of medium and light environmental-friendly launch vehicles, namely the Long March 6 and the Long March 7.〔〔〔 During early 2012, the engine system successfully passed vacuum testing.〔 It is China's first upper stage rocket engine to adopt the staged-combustion cycle. In the LM-6 upper stage it will use a single YF-115 with gimbaled mount. While the LM-7 upper stage will use four such engines. But in this latter case, two engines will be fixed and two will be gimbaled.〔 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「YF-115」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
