摘要
无操纵面飞行器又称无副翼、无襟翼或是全无舵飞行器,其原理是采用流动控制技术产生“虚拟舵面”效应,取代副翼、方向舵及升降舵等操纵面。采用射流飞行控制技术可以减轻飞行器的自身重量,使飞行器升阻比更高,气动性能、隐身性更好。本文综述了无操纵面飞行器的国内外发展现状,概述了通过环量控制实现流体飞控的方法,详述了采用后缘吹气和实现无操纵面飞行的实施原理,介绍了最新进展,最后总结了无操纵面飞行器存在的问题和未来发展。
Flapless aircraft is also known as no aileron,no flaps or all-rudderless aircraft.Its principle is to use the flow control technology to generate'virtual rudder surface',instead of the ailerons,rudders,elevators and other control surfaces to achieve the aircraft roll,yaw and pitch attitude control.Fluidic flight control technology can reduce the weight of the aircraft itself,reduce costs,at the same time,the aircraft has a higher lift-drag ratio and better aerodynamic performance and stealth.This paper reviewed the development status of flapless air vehicles both at home and abroad,summarized the implementation methods of the wing circulation control technology for flapless aircraft,explained the flight control effects and the principle by trailing edge blowing,introduced the recent progress of our team.Finally,the problems and future development paths of flapless vehicles were summarized.
