Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] attached figure 1 It is a schematic diagram of the overall structure of a flapping-wing aircraft. The flapping-wing aircraft of the present invention comprises a body 1, a first semi-rotary blade 2, a fixed shaft 3, a slewing frame 4, a second semi-rotary blade 5, a pin gear 6, a steering cam 7, a large gear 8, a first Three and a half turning fins 9, the fourth half turning fins 10, driven gear 11, driving gear 12, control motor 13 and the like. The body 1 and the fixed shaft 3 are connected by pins to keep no relative movement. The fixed shaft 3 is symmetrical and perpendicular to the longitudinal symmetry plane of the body. Shaft 3 and axially located with nut and stop washer. The main engine is fixed on the body 1, and the driving gear 12 at the shaft end meshes with two symmetrically arranged driven gears 11 to form the main transmission ...

Abstract

The invention provides a flapping-wing aircraft belonging to the technical field of aircrafts. The flapping-wing aircraft comprises an airframe, a stationary shaft, a reversing frame, a half-rotating swing blade, a pin gear, a steering cam, a gearwheel, a driven gear, a driving gear, a control motor and the like, wherein the stationary shaft and the airframe are fixed, and the reversing frame is fixedly linked with the driven gear; the driving gear and the driven gear are meshed to form a main transmission mechanism of the aircraft to drive the reversing frame and the half-rotating wing blade to rotate to generate propelling force required by the aircraft; and the control motor is driven by a first-stage gear, the cam and the pin gear to form a maneuverable control mechanism of the aircraft, and the initial position of the half-rotating wing blade is changed, so that the direction of the propelling force is changed. The flapping-wing aircraft provided by the invention is flexible in adjusting the direction of the propelling force, stronger in maneuverability and beneficial to the control for taking off, landing and flying in a complex flying space; and the main transmission mechanism and the maneuverable control mechanism are simple, high in reliability and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of flapping-wing aircraft, and in particular relates to a flapping-wing-like aircraft in which movable wings flutter in approximately one direction. Background technique [0002] The flapping-wing aircraft is an aircraft that can generate lift and maneuverability control like a bird 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. It can take off and land vertically, fly at low speed or Hover, adapted to fly in complex spaces. Although general screw-wing helicopters and fixed-wing vertical take-off and landing aircraft have the function of similar 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 c...
