多旋翼飞行器气动干扰研究综述

Review of aerodynamic interference of multi-rotor aircraft

多旋翼飞行器依靠空气动力飞行,升力系统螺旋桨布置多,可获得更大的升力;但是,多旋翼飞行器在飞行过程中气动特性受到翼间干扰和非定常来流的影响,容易造成控制质量差、工作效率降低等问题。为此,对多旋翼飞行器气动干扰进行综述。首先,针对多旋翼飞行器气动干扰情况,总结了国内外研究现状,并分析了当前研究的经验和不足;然后,简要阐述了多旋翼飞行器所需克服的技术难题;最后,对多旋翼气动干扰的研究方向提出了几点建议。

Multi-rotor aircraft relies on aerodynamic force to fly,if more propellers are arranged in lift system,the lift will be greater.But its aerodynamic characteristics are affected by the inter-rotor interference and unsteady stream to weaken the control quality and reduce work efficiency in flight.Thus,the aerodynamic interference of multi-rotor aircraft was reviewed.Firstly,present situations both at home and abroad were summarized,and the experience and deficiencies of research results were analyzed.Then,the technical problems to be overcome for multi-rotor aircraft were described emphatically.Finally,some suggestions on the research direction of aerodynamic interference were proposed.
