The invention discloses a lifting-assisting short-distance take-off system for a nose landing gear of a taxiing aircraft, which is formed by adding one or more stages of jacking device hardware and corresponding matched control program software between the bottom of a middle upright post of the nose landing gear of the taxiing aircraft and a front wheel axle, so that when the aircraft takes off and slides to a certain distance and speed, the jacking device hardware can be lifted to the bottom of the middle upright post of the nose landing gear of the taxiing aircraft. Software and hardware are started, the maximum jacking displacement between the aircraft nose and the front wheel axle is achieved, the lifting angle of the aircraft nose is maximum, the skating lift force in unit time is synchronously maximum, the take-off ground clearance condition of the aircraft is met in advance, the whole aircraft is made to break away from a runway in advance to fly into the air, and short-distance take-off is achieved. The problems that taxiing type aircrafts adopting front three-point undercarriages, including military and civil manned or unmanned aircrafts, model airplanes, toys and the like, need a long runway to take off in a taxiing mode, and are high in energy consumption, low in efficiency and harsh in runway requirement are solved. The method is applied to research, development, production, refitting and upgrading of aircrafts, and remarkable economic and social benefits can be generated.
本发明公开了滑跑式飞行器前起落架助升短距起飞系统,由在滑跑式飞行器前起落架中立柱底部与前轮轴之间增加一级或多级顶升装置硬件及相应的配套控制程序软件组成,使飞行器在起飞滑跑到一定的距离、速度时,启动本发明的软硬件,使飞行器机头与前轮轴之间达到最大顶升位移,飞行器机头抬升角度最大,在单位时间内滑跑的升力也同步最大,提前满足飞行器起飞离地条件,使飞行器整体提前脱离跑道飞向空中,实现短距起飞。解决了采用前三点式起落架的滑跑式飞行器,包括军用、民用有人或无人驾驶飞行器及航模、玩具等需要长跑道滑跑起飞且能耗高、效率低、对跑道要求苛刻的问题。其应用于飞行器研发生产、改装和升级,将产生显著的经济及社会效益。
