Fluttering-folding-active torsion hybrid drive bionic ornithopter

Abstract

The invention discloses a fluttering-folding-active torsion hybrid drive bionic ornithopter. The bionic ornithopter comprises a machine body, a fluttering mechanism, torsion mechanisms, wings on the two sides and a tail wing mechanism. The machine body comprises a front fixed frame and a rear fixed frame which are connected through a fixing shaft. Fluttering transmission gears are arranged on thefront fixed frame, torsion transmission gears are arranged on the rear fixed frame, and the transmission gears are connected with flapping wing frameworks through transmission devices. When a fluttering motor is started, synchronous pulleys on an output shaft of the fluttering motor rotate, flapping wing transmission gears are driven to rotate, and fluttering folding motion of the wings is achieved. Similarly, a torsion motor is started, and torsion motion of the wings is achieved. A tail wing transmission mechanism is fixed to the tail of the machine body, and the ornithopter steers through adjustment of a tail wing steering engine. The whole ornithopter comprises the two motors, the flexibility of the ornithopter is improved, flight efficiency is improved, the bird wing motion mode is truly simulated, and various flight functions can be achieved.

Description

technical field [0001] The invention belongs to the field of aircraft and relates to the technical field of a bionic flapping-wing aircraft, in particular to a bionic flapping-wing aircraft driven by a flapping-folding-active torsion hybrid drive. Background technique [0002] The bionic flapping wing aircraft is a new type of flying machine that imitates the flight of birds and insects and is designed and manufactured based on the principle of bionics. The bionic flapping wing aircraft usually has the characteristics of moderate size, easy to carry, flexible flight, good concealment, etc., so it has very important and extensive applications in the fields of civil and national defense. [0003] At present, most of the flapping-wing aircraft studied are single-degree-of-freedom mechanisms. This type of driving method is simple in structure, light in weight, and realizes a single form of motion. The flight flexibility and stability cannot be compared with flying creatures. Pa...

[0003] At present, most of the flapping-wing aircraft studied are single-degree-of-freedom mechanisms. This type of driving method is simple in structure, light in weight, and realizes a single form of motion. The flight flexibility and stability cannot be compared with flying creatures.

Patent (CN106043692A) provides a multi-degree-of-freedom bird-like flapping-wing aircraft that integrates flapping wings swinging, twisting, bending and folding. Although it can realize multi-degree-of-freedom movements, it has many driving parts, large mass, and complex structure, so it is not easy to miniaturize
