欧洲空间局计划发展载人航天,研制能够往返空间站的载人飞船。为掌握全部的航天器回收技术,欧空局将先研制一艘无人飞船——再入大气层无人太空密封舱,其外形类似于美国“阿波罗”飞船。预计于1995年底用“阿丽亚娜-5”运载火箭发射升空,绕地球亚轨道运行后再入大气层,返回地球。上图为无人回收舱再入大气层的情景。下图是回收舱的飞行过程示意图:1.从库鲁航天中心发射;2.火箭第一级关机被抛弃后,回收舱与运载火箭分离,炎箭第二级点火将一颗卫星送入地球同步轨道;3.回收舱运行轨道高度为1200公里;4.回收舱再入大
The European Space Agency plans to develop manned spacecraft to develop manned spacecraft capable of round-trip to and from space stations. To master all of the spacecraft recycling technologies, ESA will first develop an unmanned spacecraft - reentry unmanned space capsule, which looks similar to the United States “Apollo” spacecraft. It is expected to launch at the end of 1995 with the launch of the “Ariane -5” launch vehicle and circumnavigate the Earth’s orbit into the atmosphere and return to Earth. The picture above shows the unmanned recovery compartment into the atmosphere again. The following figure is the schematic diagram of the recovery of the capsule during the flight: 1. Launch from the Kuru Space Center; 2. After the first stage of the rocket was turned off, the recovery capsule was separated from the launch vehicle; the second stage of the Yanjian fire brought a satellite into the earth Synchronous orbit; 3 recovery bin operating orbit height of 1200 km;
