Abstract

The invention relates to a high-maneuverability flapping wing type bionic bat aircraft with a flexible structure. The high-maneuverability flapping wing type bionic bat aircraft comprises an aircraft body, a first wing vein, a second wing vein, a gear transmission assembly, a motor assembly, a first steering engine assembly and a second steering engine assembly. The gear transmission assembly comprises a main wing driving gear and an auxiliary wing driving gear. And a swinging guide rod is arranged on the main wing driving gear. The motor assembly comprises a motor, a rocker arm and a sliding block. The swing guide rod is connected with the sliding block. The first steering engine assembly and the second steering engine assembly each comprise a steering engine and a steering engine arm connected with an output shaft of the steering engine. The left side and the right side of the fuselage are each provided with a flexible rod, one end of each flexible rod is fixedly connected with the fuselage, and the other end of each flexible rod penetrates through the steering engine arm on the corresponding side and is in clearance fit with the steering engine arm. According to the aircraft, the micro motor and the steering engine are adopted as driving devices, pitching and rolling control over the attitude can be achieved in the flight process, the flight speed can be adjusted, more efficient and flexible flight performance is achieved, and the whole aircraft is simple and compact in structure and easy to miniaturize, control, manage, assemble and overhaul.

Description

technical field [0001] The invention relates to the technical field of micro biomimetic aircraft, in particular to a highly maneuverable flapping-wing bionic bat aircraft with a flexible structure and a flight control method thereof. Background technique [0002] In recent years, with the progress of micro-actuator, microcontroller, communication technology and micro-electro-mechanical technology (MEMS), especially MEMS inertial navigation technology, micro-bionic aircraft has gradually become a research hotspot in the field of micro-aircraft. Micro-bionic aircrafts mainly include Kunming-style aircraft based on flying insects and bird-like aircraft based on flying birds. [0003] Among a wide variety of micro-bionic aircraft, the flapping-wing aircraft with bats as bionic objects can combine the flexible maneuverability of insects with the energy-efficient level flight and gliding performance of birds, and has attracted widespread attention from scholars at home and abroad....

Problems solved by technology

These mechanisms are complex in structure, and their realization requires the cooperation of multiple groups of kinematic pairs, which is difficult to miniaturize, and the manipulation and control of folding wings is difficult.

In addition, the bionic bat aircraft based on this type of structure uses folding wings and tail wings to generate the lift and attitude adjustment torque required for flight drive and control control during flight, which requires additional driving devices and has high control complexity.
