1936年,在美国加州大学哥根哈姆空气动力研究所,冯·卡门教授组成空间推进技术试验小组,开始用氧气和酒精作推进剂,试验火箭推进技术,企图达到高空。小组初创,工作进展困难。 1939年,第二次世界大战爆发。美海军对这个小组提出研制飞机助飞器的任务。助飞器是一种固体火箭发动机,主要用于飞机起飞时缩短飞机的起飞距离。小组获得资助,旋即扩
In 1936, at the University of California, Cornerstone Aerodynamic Research Institute, Prof. von Karman formed a space propulsion technology test group to start using oxygen and alcohol as a propellant to test rocket propulsion technology in an attempt to reach high altitude. The group started up and the progress of the work was difficult. In 1939, the outbreak of World War II. The United States Navy proposed to this group the task of developing aircraft aid aircraft. Aid is a solid rocket motor, mainly used for taking off the aircraft to shorten the take-off distance of the aircraft. The group is funded and swiftly expanded
