Abstract

The invention discloses a flapping-wing micro-aircraft based on motor antisymmetric arrangement driving, and belongs to the field of micro-aircrafts. When a driving structure is used for driving, motors which are arranged in an anti-symmetric mode symmetrically rotate reversely to eliminate the influence of motor torque, so that large-amplitude vibration of a fuselage in the horizontal direction is eliminated, and the stability during flight is improved; the motor drive arranged in an anti-symmetric mode is equivalent to motor parallel drive, the problems of insufficient drive force and drive power of a single existing micro motor are solved, and the requirement for high flapping frequency of the flapping-wing micro aircraft in a special flight environment can be met. A mechanism for passive torsion during flapping of a wing is arranged at the root of the wing, so that the wing flaps downwards in a small-attack-angle attitude to obtain larger beneficial aerodynamic lift force and flaps upwards in a large-attack-angle attitude to obtain smaller aerodynamic resistance, and the average beneficial aerodynamic lift force of the flapping-wing micro aircraft is increased by means of a torsion mechanism. The device also has the advantages of simple structure, high integration level, firmness, reliability and convenience in manufacturing and assembling.

Description

technical field [0001] The invention belongs to the field of micro-aircraft, and relates to a flapping-wing micro-aircraft driven by anti-symmetric layout of motors. Background technique [0002] The micro-aircraft has outstanding features such as small size, good concealment, light weight, low cost, strong function, easy to carry, easy to operate, and can work in unique aerodynamic fields including low Reynolds number environments. It is widely used in such as Surveillance, biochemical agent detection, battlefield survey, traffic monitoring, and urban information collection, etc., are divided into three categories: fixed-wing MAVs, rotary-wing MAVs, and flapping-wing MAVs according to different flight modes and overall structural layouts. Among them, the flapping-wing micro-aircraft has unique advantages: it has good concealment according to the bionic design; the flapping wing has the function of generating aerodynamic lift and thrust; it can optimize the flapping mode and...
