The invention discloses an overall aerodynamic layout of an unmanned tilt rotorcraft. The overall aerodynamic layout comprises a fuselage, wings, an engine compartment, rotors, a tilting mechanism anda V tail, the fuselage adopts a streamline shape, and wings and the fuselage are in fusion transition. Each wing comprises an inner-section wing and an outer-section wing, the inner-section wing is astraight wing, a flap and an aileron are arranged on the inner-section wing, the outer-section wing is sharpened and turned upwards, and the aspect ratio of the wing is 10-15. And a lifting rudder isarranged on the V tail. The engine compartment, the rotor wing and the tilting mechanism are arranged between the inner section wing and the outer section wing in an attached mode. During vertical take-off or landing, the rotor wings are in a vertical state, the outer section wings, the flaps and the ailerons deflect downwards by about 90 degrees, and the influence of downwash flow of the rotor wings is reduced. During forward flight, the rotor wings are in a horizontal state, and the outer-section wings, the flaps and the ailerons return to normal states. During storage, the outer-section wings and the rotor blades are folded, and the wings rotate around the rotating center to be parallel to the fuselage. The overall aerodynamic layout of the unmanned tilt rotorcraft has the advantages of being capable of vertically taking off and landing, high in lift-drag ratio, long in endurance time, high in hovering efficiency, small in storage space and the like, and can be used for aerodynamiclayout design of large and medium-sized unmanned tilt rotorcrafts.

    一种无人倾转旋翼机总体气动布局,包括:机身、机翼、发动机舱、旋翼、倾转机构和V尾。机身采用流线型外形,机翼与机身融合过渡。机翼包括内段机翼和外段机翼,内段机翼为平直翼,上面布置有襟翼、副翼,外段机翼尖削上反,机翼展弦比10~15。V尾上布置有升降方向舵。发动机舱和旋翼、倾转机构贴临布置在内段机翼与外段机翼之间。垂直起飞或降落时,旋翼处于垂直状态,外段机翼和襟翼、副翼向下偏转约90°,降低旋翼下洗流影响。前飞时,旋翼处于水平状态,外段机翼和襟翼、副翼恢复正常状态。储存时,外段机翼和旋翼桨叶折叠,机翼绕旋转中心旋转至与机身平行。本发明提供的无人倾转旋翼机总体气动布局具有可垂直起降、升阻比高、续航时间长、悬停效率高、储存空间小等优点,可用于大中型无人倾转旋翼机的气动布局设计。
