Miniature double-flapping-wing air vehicle

Abstract

The invention discloses a miniature double-flapping-wing air vehicle which comprises a middle connecting structure, an attitude control steering engine, a wing root position control mechanism, a frontflapping wing system and a rear flapping wing system, wherein the front flapping wing system and the rear flapping wing system are identical. According to the miniature double-flapping-wing aircraft,the lift force generation is further enhanced by virtue of a double-wing opening-closing mechanism; the flapping frequencies of the front and rear pairs of wings are influenced by changing the rotating speed of the motor so that the two pairs of wings generate front and rear asymmetric lift force to generate pitching control moment; a wing root position control mechanism is controlled by an attitude control steering engine to change the positions of two groups of wing root rods, and the tensioning degree of a flapping wing membrane is changed so that a left wing and a right wing generate different lifting forces to generate rolling control torque. The two sets of wing roots are controlled through one steering engine, the control mechanism is simplified, the control difficulty is reduced,weight reduction is achieved, resources are saved, and besides, pneumatic lift augmentation is achieved through an opening-closing high lift mechanism.

Description

technical field [0001] The invention relates to the field of micro-aircraft, in particular to a miniature double flapping-wing aircraft. Background technique [0002] With the continuous innovation of aircraft design concepts and the great progress of microelectronics technology at the end of the last century, micro air vehicles were proposed and developed rapidly. With the characteristics of small size, light weight and strong maneuverability, micro air vehicles are suitable for reconnaissance, exploration and rescue assistance in complex environments, and have broad application prospects. As an important branch of micro-aircraft, the bionic flapping-wing micro-aircraft gradually began to appear with the development of bionics design. The flapping-wing micro-aircraft relies on the reciprocating flapping of the flapping wings to generate lift, and generates control torque through the fine control of the flapping-wing flapping process, which can maintain high aerodynamic eff...
