| 摘 要： | 倾转机翼飞行器不仅拥有直升机固有的垂直起降能力,还具备传统固定翼飞行器特有的高速巡航的特点,是目前军民用飞行器研究的热点之一。针对传统倾转机翼飞行器存在螺旋桨气动效率低、倾转机构复杂的问题,提出四发串列式倾转机翼垂直起降布局形式,对该布局飞行器进行总体设计,完成螺旋桨周围流场特性、螺旋桨间干扰特性、螺旋桨和机翼之间干扰特性的研究分析,并制作验证机进行验证。结果表明:该布局很好地解决了螺旋桨气动效率低、传动机构复杂的问题,具有较强的可实现性及实用性。

| Abstract: | Vertical take-off and landing (VTOL) aircraft not only has the ability of vertical take-off and landing like helicopter, but also be provided with high-speed cruise capability as traditional fixed-wing . Aircraft. VTOL is one of the hot spots of research in both military and civilian unmanned aerial vehicles. In this paper, a new layout, tilt-tandem wing and quadrotor of VTOL aircraft, is proposed to avoid the defects of .low aerodynamic efficiency and complicated tilting mechanism. Conceptual design and aerodynamics simulation also have been carried out. the aerodynamic characteristics of aircraft with the interference of propellers Further more, prototypes are made and experienced several flight tests validation. The flight tests validation shows that this layout can avoid the disadvantages of low efficiency propellers and complicated tilting mechanism,which is reliable and practical. |
