订单来得快去得快军用航空领域主要的进步基本都是和动力系统的革命性跨越密切相关的,从活塞螺旋桨到喷气推进是最具里程碑意义的伟大变革,也将人类对飞行速度的追求提升到了一个新的水平。在早期理论积累和完善阶段,欧洲人首开喷气之先,英、德两国在此领域搞得风生水起,竞相推出新型飞机平台以验证喷气飞行 Orders go faster The main advances in military aviation are basically related to the revolutionary leaps in powertrain. From piston propellers to jet propulsion are the most landmark milestones and the pursuit of human flight speed. To a new level. In the early stages of theoretical accumulation and improvement, Europeans first started the jet, and Britain and Germany made great spells in this area. They were competing to launch a new aircraft platform to verify jet flights
