Miniature dragonfly-imitating double-flapping-wing aircraft

Abstract

The invention discloses a miniature dragonfly-imitating double-flapping-wing aircraft, which is constituted by a nose, a fuselage, four flapping wings, a tail and a head steering engine. The fuselagecomprises a fuselage skeleton, and further comprises transmission modules and flight control modules of the flapping wings; the transmission modules each comprise a micro motor, a first-stage reduction gear, a second-stage reduction gear, two output gears, two connecting rods, a rocker arm a and a rocker arm b; the first-stage reduction gears, the second-stage reduction gears and the output gearsconstitute second-stage gear reduction mechanisms; the output gears, the connecting rods and the rocker arms constitute two sets of symmetrical four-linkage mechanisms; and during working, the reduction mechanisms and the four-linkage mechanisms in the transmission modules are driven through the micro motors, finally the flapping wings are driven to achieve reciprocating flapping, and aerodynamiclift in the vertical direction is generated. Manufacturing is easy, the high design precision is easy to achieve, each single motor can drive the two corresponding flapping wings through the simple and compact structure, flapping of the front and rear flapping wings is completely symmetrical, the lift can be increased through the influence between the multiple flapping wings, and the flight performance is improved.

Description

technical field [0001] The invention relates to the field of flapping-wing aircraft design, in particular to a miniature dragonfly imitating double flapping-wing aircraft. Background technique [0002] Micro flapping-wing aircraft is a new concept aircraft that imitates the flight of birds or insects. Compared with fixed-wing and rotary-wing flying, flapping-wing flight includes their advantages. It can take off, accelerate and hover quickly, and is highly maneuverable. and flexibility. With the rapid development of science and technology, especially the development of micro-electromechanical systems (MENS) technology has provided convenience for the manufacture and processing of micro-aircraft, the application of micro-aircraft (MAV) has become more and more extensive, and has important advantages in civil and military fields. Very broad application prospects. [0003] As one of the creatures with the best flight performance in nature, dragonflies can realize forward, bac...

Patent CN200942872Y provides a dragonfly imitation double-flapping wing aircraft. The defect of this patent is very obvious. The left and right flapping wings are completely asymmetrical. While the left (right) flapping wings flap upwards, the right (left) flaps downwards. , causing the flight stability of the aircraft to be very poor, and even unable to fly effectively

CN201010140927.7 proposes a miniature dragonfly-like double-flapping wing aircraft. The tail of the aircraft uses a fixed-wing horizontal tail and a vertical tail to control the flight attitude of the aircraft. It is obviously different from the flight control of dragonflies in nature, and the bionic degree is not high.

CN201710580936.X proposes a variable-amplitude imitation dragonfly flapping wing aircraft. The aircraft uses a single steering gear to simultaneously control the flapping amplitude of the left and right wings, which improves the maneuverability of the aircraft. By changing the flapping amplitude of the left and right wings Amplitude, to achieve pitch flight control, but it is difficult to achieve yaw control

CN201810193389.4 proposes a multi-degree-of-freedom imitation dragonfly flapping wing aircraft. The aircraft adopts the form of four-drive flapping wings. The four flapping wings can be rotated independently, and the flight control efficiency is high. Pitching, yaw, and hovering can be easily realized. and other actions, but the structure is too complex, the production and assembly precision requirements are high, and it is difficult to achieve miniaturization
