喷气式军用运输机的发展美国的蔡斯飞机公司是个小公司,成立于1943年,只生产过一些全金属的运输滑翔机,如CG-18和G-20等型号。1951年4月21日,这家公司在G-20型运输滑翔机的机翼上装了4台喷气式发动机(两台一组分装于左、右两个吊舱),从而发展成为美国第一种喷气式军用运输机——C-123B型飞机。由于纯喷气飞机在中、低空的经济性较差,在20世纪50年代设计的军用运输机大多采用涡轮螺旋桨动力装置。美国洛克希德公司从1951年7月11日开始研制的
Development of Jet Military Transport Aircraft Zeiss Aircraft Company of the United States is a small company established in 1943 that produced only all-metal transport gliders such as the CG-18 and G-20 models. On April 21, 1951, the company built four jet engines on the wings of the G-20 transport glider (two in one group on the left and two on the right) to develop into the No. 1 U.S. Jet military transport aircraft - C-123B aircraft. Due to the low economy of pure jet aircraft in mid-low altitude, most of the military transport aircraft designed in the 1950s used turboprop power units. The United States Lockheed started from July 11, 1951
