长征 10B | 演示飞行任务

描述

The Long March 10B is a reusable launch vehicle based on the 1st stage of the Long March 10A, in turn derived from a single 1st stage core of the Long March 10, with 7 YF-100 series kerosene/liquid oxygen staged-combustion cycle engines on the 1st stage. Like the Long March 10A, the 10B’s 1st stage is designed to be recovered downrange by a recovery barge equipped with an arrestor net and support frame, with the 1st stage landing on the net’s cables using its grid fins. The 2nd stage, however, uses a single YF-219 gas generator cycle methane/liquid oxygen engine with 140 tonnes of thrust.

长征十号 B 是一款可复用运载火箭，基于长征十号 A 的第一级——后者又源自长征十号的单个第一级芯级，第一级采用 7 台 YF-100 系列煤油/液氧分级燃烧循环发动机。与长征十号 A 一样，10B 的第一级设计为由配备拦阻网和支撑框架的回收驳船在下靶场回收，第一级利用其栅格舵着陆于网的缆绳上。 不过，第二级采用单台 YF-219 燃气发生器循环甲烷/液氧发动机，推力 140 吨。
