长征 12B | 演示飞行任务 (千帆极轨组#10)

描述

Long March 12B/Changzheng 12B (LM-12B/CZ-12B) is a reusable orbital launch vehicle developed by the China Aerospace Science and Technology Commercial Launch Vehicle Group (CACL), a subsidiary company 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 kerosene/liquid oxygen powered rocket engines in both stages. The first stage uses 9 YF-102R engines and the second stage uses 1 YF-102V engine, both 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.

长征十二号 B（LM-12B/CZ-12B）是一款可复用入轨运载火箭，由国有企业中国航天科技集团公司（CASC）旗下子公司中国航天科技商业运载火箭集团（CACL）研制。该火箭以长征十二号为基础，但为实现第一级可复用而进行了大幅重新设计，两级均采用燃气发生器循环的煤油/液氧火箭发动机。 第一级采用 9 台 YF-102R 发动机，第二级采用 1 台 YF-102V 发动机，二者均来自 CASC 航天推进技术研究院（AALPT）。 在回收第一级的发射任务中，它将着陆于位于甘肃省民勤县的下靶场着陆坪。
