以莫斯科为基地的Zvezda航天服生产公司正在开发宇航员空间行走时用的安全辅助装置。它是一种被称作USK的小型独立机动单元,已经用于航天飞机EVA(舱外行走)中.俄罗斯和美国的这种装置用于无系绳的宇航员在舱外漂浮的场合,装置象一个框架,重约40kg,USK装置适合于奥里安(Orlan)EVA航天服,与背负式航天服联成一体,能连续使用8小时。 USK采用以压缩空气为动力的冷气推进系统,有两组推力器,每组8个,每个推力器能产生500g的推力。一个自主计算机系统提供自动姿态控制,
The Moscow-based Zvezda spacesuit manufacturing company is developing safety aids for spacewalks astronauts. It is a small, stand-alone motorized unit called the USK that has been used in the Space Shuttle EVA (extra-vehicular walk), a device of Russia and the United States that is used in the case of a ropeless astronaut floating outside a capsule, Like a frame weighing about 40kg, the USK unit fits into the Orlan EVA spacesuit and is integrated with a knit space suit for up to 8 hours of continuous use. USK uses a compressed air-powered air conditioning propulsion system with two sets of thrusters, eight in each, that produce 500 g of thrust per thruster. An autonomous computer system provides automatic attitude control,
