H-2转移飞行器(HTV)由日本宇宙航空研究开发机构(JAXA)负责研制,是一种向“国际空间站”(ISS)日本实验舱(JEM)运送物资为主要目的的无人货运飞船(一次性使用、不可回收)。三菱重工业公司(MHI)为其主承包商。迄今日本已发射3个HTV,完成了既定的飞行任务。1HTV概况从推进产品系列化发展、资源综合利用和好、快、省发展等方面考虑,JAXA和MHI公司等希望以HTV核心模块为基础,能逐渐发展成为集轨道运输、轨道服务、轨道回收、载人飞船以及载人月球探测与运输于一体的多功能航天器;日本已决定通过改 Developed by the Japan Aerospace Exploration Agency (JAXA), the H-2 transfer aircraft (HTV) is a unmanned cargo spacecraft primarily for the purpose of transporting supplies to the International Space Station (ISS) Japan Laboratory (JEM) (One-time use, non-recoverable). Mitsubishi Heavy Industries (MHI) as its main contractor. To date, Japan has fired three HTVs and completed its mission. 1HTV overview From the promotion of product development, comprehensive utilization of resources and good, fast, provincial development considerations, JAXA and MHI companies hope to HTV core module as the basis, can gradually develop into a set of rail transport, orbital services, orbit recovery, Manned spacecraft and multi-purpose spacecraft manned by lunar exploration and transport; Japan has decided to change
