据美《航空周刊与空间技术》1978年3月20日报道: 苏联已经制成了一架新的三角翼型重复使用的载人空间飞行器,作为俄国拥有自己的航天飞机能力的初始步骤。为确定航空动力学和宇航器驾驶操纵性能,俄国航天飞机的实验机在空中从一架图-95熊式轰炸机上作了降落试验。这些试验是可以和美国航天飞机轨道器最近进行的试验相媲美的。苏联的这个实验机在一个独立的航空实验设 According to the United States, “Aviation Week and Space Technology” reported on March 20, 1978: The Soviet Union has produced a new delta wing-type reusable manned spacecraft as Russia’s initial steps to own the capabilities of the space shuttle. In order to determine aerodynamics and spacecraft maneuverability, a Russian space shuttle’s test rig was dropped in-flight from a Tu-95 bomber. These tests are comparable to the recent tests carried out by the U.S. space shuttle orbiter. The Soviet experimental machine was set up in an independent aviation experiment
