Abstract

The invention discloses a coaxial opposite-rotating dual-rotating-wing duct type vertical take-off and landing aircraft. The coaxial opposite-rotating dual-rotating-wing duct type vertical take-off and landing aircraft is composed of a loading bin, a duct receiver, a flow guiding rudder, an opposite-rotating driving motor and two opposite-rotating rotors. The loading bin is located above the duct receiver which is of an annular cavity structure, opposite-rotating rotor blades are wrapped so that extra front edge suction force can be generated, and the power requirement of the aircraft is lowered while the lifting force of the aircraft is increased. An installing frame is fixed to the lower end of the inner wall of the duct receiver. The flow guiding rudder is in butt joint with the installing frame. The opposite-rotating driving motor is installed on the upper portion of the installing frame. The two opposite-rotating rotors are fixedly connected with an output shaft of the opposite-rotating driving motor, and an undercarriage is embedded in the lower portion of the outer side wall of the duct receiver. Coaxial opposite-rotating dual rotating wings counteract self-rotating moment, and stable control over the posture of the aircraft is facilitated. Pneumatic loads of each stage of rotor blades are reduced through the opposite-rotating rotors, pneumatic loss can be reduced easily, meanwhile the opposite-rotating rotor blades reduce rotational flow loss, pneumatic efficiency is greatly improved, and time of endurance is prolonged.

Description

technical field [0001] The invention relates to a vertical take-off and landing aircraft, in particular to a coaxial counter-rotating double-rotor ducted vertical take-off and landing aircraft. Background technique [0002] In the existing published technical literature "Research Status and Key Technologies of Miniature Quadrotor Aircraft" ("Electronic Optics and Control" 2007 (06)), the extensive application value and application prospects of vertical take-off and landing aircraft are discussed, as well as the current multi-rotor aircraft. The state of aircraft technology. The comparison between the literature and the actual application status shows that most of the current quadrotor aircraft use open propellers, which occupy a large space area and are limited by the aerodynamic layout. The blade diameter is constrained by the aircraft wheelbase, and there is blade aerodynamic interference. Efficiency is difficult to improve. Under the current energy storage technology co...
