Bionic ornithopter imitating butterfly wings

Abstract

A bionic flapping wing aircraft imitating butterfly wings belongs to the technical field of aircrafts and is characterized in that a motor in the bionic flapping wing aircraft is connected with a secondary gear reducer, flapping wing movement is realized on the basis of the quick return characteristic of a crankshaft plate sliding groove mechanism, and the front end of a driving mechanism is meshed through incomplete tooth surfaces, so that left and right flapping wing movement symmetry and flight stability are realized; a single steering engine is adopted to control the direction of the empennage, the structure can be greatly simplified while control is guaranteed, the weight of the whole aircraft is reduced, and flight control has operability by additionally designing winglets; bionic butterfly wings with large-area flexible wings are selected on the wing structures to generate enough lift force; the flapping wing frequency can be changed through information of sensors such as the fixed-height module, so that tasks such as fixed-height flight are achieved, and the flapping wing device has the advantages of being light in structure, simple and reliable in transmission and stable in flight.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to a bionic flapping-wing aircraft imitating butterfly wings. Background technique [0002] In nature, birds and insects have evolved body structures that can fly freely in the air through the continuous evolution process. In the field of flapping-wing aircraft, humans have developed flapping-wing aircraft of different shapes by continuously drawing on the body structure of animals in nature. In the future, MAVs can be widely used in civilian and military applications. In the civilian field, they can replace humans in dangerous areas such as nuclear-contaminated areas to perform tasks. In the military field, they can carry out future combat concepts such as low-altitude reconnaissance and urban warfare. [0003] The common drive structures of flapping-wing aircraft include single crank double rockers, double crank double rockers, and crank slider structures. These stru...
