The invention relates to the field of overall layout design of aircrafts, in particular to a short-distance take-off and landing aircraft adopting a front-low rear-high type double-wing layout, whichcomprises an aircraft body, a front wing and a rear wing; the mounting height of the rear wing is greater than that of the front wing, and an engine is mounted on the upper surface of the front wing and matched with an external blowing flap at the tail edge of the rear wing; the installation height of the engine meets the requirements that when the aircraft cruises, the external blowing flap of the rear wing is in a retracting state, engine jet flows pass through the lower portion of the rear wing and do not interact with the rear wing, and when the aircraft takes off and lands, the external blowing flap generates a deflection angle, and the jet flows of the engine penetrate through the external blowing flap to increase lift force. By adopting a double-wing layout form, the wingspan is smaller, and the runway width required by the aircraft can be reduced; the lift augmentation effect can be improved and the take-off and landing distance can be reduced by adopting the front-low and rear-high double-wing layout and adopting the novel external blowing type power lift augmentation system.
本发明涉及飞行器总体布局设计领域,特别涉及一种采用前低后高式双翼布局的短距离起降飞行器,包括机身、前翼和后翼,其中后翼的安装高度大于前翼,发动机安装在前翼的上表面,与后翼尾缘处的外部吹气襟翼匹配,发动机的安装高度满足当飞行器巡航时,后翼的外部吹气襟翼处于收回状态,发动机射流从后翼下方通过,不与后翼发生相互作用,当飞行器起降时,外部吹气襟翼产生偏角,发动机的射流穿过外部吹气襟翼增加升力。本发明采用双翼布局形式使翼展更小,可以降低飞行器所需的跑道宽度,前低后高式双翼布局并采用新型外吹式动力增升系统能提高增升效果、降低起降距离。
