自1903年美国莱特兄弟首次实现了动力飞行以后,在飞机失事时如何挽救飞行员的生命便提上了议事日程。法国于1917年首先把降落伞用于军用飞机。一战期间,约有八百名气球观测员从失事的气球上跳伞获救。二战时,战斗机的时速已提高到600公里以上,只靠飞行员的体力爬出座舱跳伞逃生越来越困难,德国首先开始了对飞行弹射座椅的研究并率先用作实战。战后,弹射座椅在英国、美国、瑞典等国迅速发展,成为高速军用飞机必不可少的救生设备。
Since the United States Wright brothers first achieved powered flight in 1903, how to save pilot’s lives in the event of a plane crash was put on the agenda. France first used a parachute in military aircraft in 1917. During World War I, about 800 balloon observers were rescued from paralyzing balloons. In World War II, the speed of fighter jets has risen to more than 600 kilometers per hour. It is becoming more and more difficult for a pilot to jump out of a cabin just to escape by parachute. Germany first started the study on the flight ejection seat and took the lead in actual combat. After the war, the ejection seat developed rapidly in Britain, the United States, Sweden and other countries and became an indispensable lifesaving device for high-speed military aircraft.
