现代空中的民用交通运输工具目前正朝着超音速运输机的方向发展。这是时代的要求,是科学技术发展的结果。美国的超音速运输机由于环境、经济和技术标准的要求,可能在200C—2010年之间进入使用状态。标志着高速民用机(HSCT)飞行速度的马赫数(马赫数等于速度与音速之比)
Modern civil transport vehicles are currently moving in the direction of supersonic transport aircraft. This is the requirement of the times and is the result of the development of science and technology. The U.S. supersonic transport aircraft may enter service between 200C and 2010 due to environmental, economic, and technical standards. Mach number (Mach number equals ratio of speed to speed of sound) that marks the speed of high speed civil aircraft (HSCT)
