在欧空局支持下,法国宇航公司将试验再入大气层试验飞行器(ARD)。锥形ARD重2.8 t,首次飞行试验打算按排在1996年年底,到时将随阿里安5运载火箭的第二次发射升空(因阿里安5火箭首次发射失败,第二次发射估计将推迟到1997年进行)。其试验目的是欧空局为乘员转移飞行器(CTV)的研制积累经验,以便挤身阿尔法国际空间站。 ARD将实现有控再入大气,使着陆精度达4～5 km,这比阿波罗再入舱着陆精度高3倍。试验的第二目的是能否解决77～54 km高度间300 s的通信暂时中断现象。试验的另一个
With ESA support, Aeroflot will test re-entry into the Atmospheric Test Vehicle (ARD). The cone-shaped ARD weighs 2.8 t and the first flight test is scheduled to be scheduled at the end of 1996 and will be followed by the second launch of the Arion 5 launch vehicle (due to the first launch of the Ariane 5 rocket unsuccessfully, the second launch estimate Postponed until 1997). Its purpose is to gain experience with the development of Crew Transfer Vehicles (CTVs) by ESA to enable it to penetrate the Alpha Space Station. The ARD will allow re-entry into the atmosphere with landing accuracy of 4 to 5 km, which is three times better than Apollo reentry navigation. The second purpose of the test is whether or not a temporary communication interruption of 300 s between 77 and 54 km can be solved. Another test
