The invention relates to a dual-mode four-rotor aircraft which comprises a fuselage, an arc shell, a short wing of the arc shell, a long wing of the arc shell, a short wing of the fuselage and a long wing of the fuselage. According to the generality that a traditional four-rotor wing and a traditional four-propeller fixed wing are both provided with four sets of propeller power systems and the relative position difference of X-shaped arrangement and linear parallel arrangement of four sets of propellers, two sets of long half wings and short half wings which are in mirror symmetry are designed, and a single-wing rotation switching mode is adopted; the requirements of airfoils of four-rotor and four-paddle fixed wings and relative positions of propellers are mainly met. Autonomous repeated switching between a fixed-wing configuration and a four-rotor configuration is achieved, and compared with a tilt-rotor aircraft configuration switching mechanism, the mechanism is simpler and more reliable, and control is more stable; compared with a composite four-rotor aircraft, a special lifting power device does not need to be arranged, and the load utilization rate is higher.
本发明涉及一种双模式四旋翼飞行器,包括机身、圆弧壳体、圆弧壳体的短翼、圆弧壳体的长翼、机身的短翼和机身的长翼;针对传统四旋翼和四桨固定翼都具有四套螺旋桨动力系统的共性,以及四套螺旋桨“X”型排布和“一”型并列的相对位置差异,设计出两组镜像对称的长半翼和短半翼,采用单翼旋转切换方式,主要满足四旋翼和四桨固定翼的翼型和螺旋桨相对位置。发明在固定翼和四旋翼两种构型间自主反复切换,相较于倾转旋翼飞行器构型切换机构更加简单可靠、控制更加稳定;相较于复合四旋翼飞行器不用设置专门升降动力装置、载荷利用率更高。
