Bionic three-dimensional flapping wing aircraft based on cross axis hinge and driving method thereof

Abstract

The invention provides a bionic three-dimensional flapping wing aircraft based on a cross axis hinge and a driving method thereof. The bionic three-dimensional flapping wing aircraft based on the cross axis hinge comprises a frame (1), a flapping driving mechanism (2), a left flapping wing (4), a right flapping wing (5), a folding control mechanism and a tail wing (6). The folding control mechanism comprises a folding controller (5), a first folding link (5D) and a second folding link (5E). Flapping and folding motion have the same period, the phase difference is 90 degrees. The invention hasthe advantages that: (1) the wings are fully unfolded when flapping downward, and the wings are folded when flapping upward suitably, and the movement can be closer to the movement of birds, and the biomimetic degree is high, the aerodynamic efficiency is high, the payload is large, the maneuverability is good, and the like. (2) The flapping process and the folding process share the same motor drive, which simplifies the complexity of the system.

Description

technical field [0001] The invention belongs to the technical field of bionic aircraft, and in particular relates to a bionic three-dimensional flapping-wing aircraft based on a cross-axis hinge and a driving method. Background technique [0002] The micro flapping wing aircraft is a new concept aircraft that imitates the flight of birds. It has the advantages of small size, light weight, maneuverability and high efficiency. If it is equipped with sensors and related data transmission and flight control systems, it will form a micro flapping wing unmanned machine platform, it will have broad application prospects. Around this topic, various countries have developed controllable flapping-wing aircraft, among which the more successful ones include the "Microbat" jointly developed by AeroVironment of the United States and the University of California and the "Delfly" of Delft University in the Netherlands. However, these flapping-wing aircraft are far from The aircraft platfor...

AI Technical Summary

Problems solved by technology

Its shortcoming is that the whole mechanism is controlled by three independent motors, which brings unnecessary waste to the aircraft, and the three independent systems are connected in series in the control, so the reliability is low, and the composition of the mechanism is relatively complicated, which is difficult to lighten. Quantification, miniaturization, limited application on micro flapping wing aircraft
