The invention relates to a composite vertical take-off and landing (VTOL) efficient and high-speed aircraft. The invention provides a composite tilting wing tandem autorotation double-rotor aircraft.Two pairs of main lift rotor sets 5 are longitudinally arranged on the upper portion of an aircraft body 1, a fixed wing 2 is arranged in the middle of the aircraft body 1, two auxiliary power short wings 4 are arranged at the two ends of the fixed wing 2, ailerons 8 are arranged on the fixed wing 2, and parallel empennages 3, vertical empennages 6 and undercarriages 7 are arranged on the aircraftbody 1. The aerodynamic layout design of the composite tilting wing tandem autorotation double-rotor aircraft avoids the technical defects of the existing composite and tilting aircrafts, the tandemarrangement of the main lift suspended wings is adopted, and the rotor design defines the rotor group and the tilting power short wings according to the aerodynamic requirements of vertical take-off and landing, hovering and autorotation rotor mode cruising. The loading efficiency of the aircraft is higher than that of an existing composite helicopter, an existing tilt rotor aircraft and an existing composite multi-rotor aircraft.
本发明涉及一种复合式垂直起降(VTOL)高效、高速飞行器。一种复合式倾转机翼纵列自转双旋翼飞行器,飞行器机体1上部纵列布置两付主升力旋翼组5,机体1中部布置有固定机翼2,固定机翼2两端布置有两副动力短翼4,固定机翼2上布置有副翼8,机体1上布置有平行尾翼3、垂直尾翼6、起落架7。复合式倾转机翼纵列自转双旋翼飞行器的气动布局设计避开了现有复合式、倾转类飞行器所存在的技术缺陷,采用纵列布置主升力悬翼,旋翼设计以垂直起降、悬停、自转旋翼模式巡航的气动要求定义旋翼组,倾转动力短翼,其载荷效率高于现有复合式直升机、倾转旋翼机、复合式多旋翼机。
