Double-drive type ornithopter

Abstract

The invention discloses a double-drive type ornithopter and belongs to the technical field of aircrafts. The ornithopter is composed of a rack, an ornithopter body, four rotating wings, rotating boxes, main motors, a control steering engine and the like. The rack is fixed to the ornithopter body. The rotating wings are fixedly connected with output shafts of the rotating boxes. The main motors drive the rotating boxes and the rotating wings to rotate relative to the rack through transmission of first-level gears, and thrust needed by the ornithopter is generated. The initial direction of the rotating wings is changed through transmission of second-level bevel gears, and therefore the direction of the thrust is changed. The thrust and the directions of the two sides of the ornithopter body of the double-drive type ornithopter can be independently and flexibly adjusted, the maneuvering characteristic is good, and flight, take-off and landing in complex space are better controlled. A main drive and maneuverability control mechanism is simple, compact in structure and high in reliability.

Description

technical field [0001] The invention belongs to the technical field of aircraft, in particular to a dual-drive flapping-wing aircraft with movable wings flapping in one direction. Background technique [0002] The flapping-wing aircraft is an aircraft that can generate lift and maneuverability control like an insect through the active movement of movable wings. It has stronger maneuverability than fixed-wing aircraft. It does not need a runway for take-off and landing, and can take off and land at a low speed or Hover, adapted to fly in complex spaces. Although general rotary-wing helicopters and fixed-wing vertical take-off and landing aircraft have the function of class flapping-wing aircraft, their mechanical structures and control mechanisms are complicated and the cost is high. The known flapping wing aircraft (CN201380963Y) has a pair of flapping wings flapping up and down to generate lift, while the flapping wings can change their motion attitude to change the direct...

Problems solved by technology

[0005] In order to overcome the shortcomings of the existing aircraft structure and control mechanism, such as complex structure, poor maneuverability, small available space, and high cost, the present invention provides a dual-drive flapping-wing aircraft, which is expected to have a simple transmission mechanism and a small space occupied by the control mechanism. , the size and direction of the aerodynamic forces on both sides of the fuselage can be flexibly adjusted, and can realize functions such as vertical lifting, horizontal forward and backward, horizontal left and right lateral movement, hovering in the air, flexible steering, etc.
