A double-rotor disc-shaped UAV

Abstract

The invention discloses a double-rotor butterfly UAV, which belongs to the technical field of aircraft. The UAV is composed of body, upper rotor, lower rotor, transmission system, rudder control system, positioning wheel system and so on. The upper rotor is located at the upper part of the fuselage, the lower rotor is located at the lower part of the fuselage, the driving wheel of the transmission system and the rudder blade of the rudder control system are located between the upper and lower rotors, the driving wheel is directly in contact with the discs of the upper and lower rotors, and the positioning gear train is distributed on the disc. On the circumference of the disk, the contact pressure between the upper and lower rotors and the driving wheel is maintained and rotates around the center of the body. The driving wheel of the drive train drives the upper rotor and the lower rotor to rotate at a constant speed in reverse to generate the thrust required by the UAV. The steering gear changes the initial orientation of the rudder blade, thereby changing the distribution and direction of the thrust. The size and direction of the front and rear thrust of the double-rotor butterfly UAV body can be independently and flexibly adjusted, and the maneuverability is strong, which is beneficial to flight and take-off and landing control in complex spaces.

Description

technical field [0001] The invention belongs to the technical field of rotorcraft, and in particular relates to a double-rotor dish-shaped unmanned aerial vehicle. Background technique [0002] Rotorcraft is an aircraft that generates lift and maneuverability control through the active movement of the rotor. It has stronger maneuverability than fixed-wing aircraft. It does not require a runway for take-off and landing. It can take off and land vertically, fly at low speed or hover. flying in space. The general rotor helicopter rotor cantilever length is large, the carrying capacity is small, the flight resistance is large, and the empennage and the complex pitch control mechanism are required to control the aerial attitude and maneuverability of the aircraft, the structure is complex and the cost is high. A well-known dual-rotor UAV (CN106428543A) uses the principle of a mechanical gyroscope to hinge a pair of rotors as rotors on the inner frame, the inner frame is hinged t...

Problems solved by technology

[0003] In order to overcome the shortcomings of the existing rotorcraft rotor control mechanism, such as complex rotor control mechanism, large rotor cantilever length, small carrying capacity, and large flight resistance, the present invention provides a double-rotor dish-shaped unmanned aerial vehicle, in the hope that the unmanned aerial vehicle has a simple transmission mechanism, The control mechanism occupies a small space, and the size and direction of the aerodynamic force at the front and rear of the fuselage can be flexibly adjusted. It can realize functions such as vertical lifting, horizontal forward and backward, hovering in the air, and flexible steering.
