Bionic hummingbird aircraft capable of hovering, and control method thereof

Abstract

The invention relates to a bionic hummingbird aircraft capable of hovering, and a control method thereof. The bionic hummingbird aircraft capable of hovering comprises a flapping wing driving mechanism, a first wing and a second wing which are symmetrically arranged on the left side and the right side of the flapping wing driving mechanism, a first steering engine assembly used for adjusting the flapping plane of the first wing, a second steering engine assembly used for adjusting the flapping plane of the second wing, a tail arranged below the flapping wing driving mechanism, and a third steering engine assembly used for driving the tail to move. Amplitude amplification is achieved through mutual meshing cooperation of a set of gears, and the effect of improving the lift force can be achieved. Power transmission is carried out through the universal coupling, independent tilting of wing flapping planes on the two sides can be achieved, pitching and yawing control can be achieved by tilting the wing flapping planes on the two sides, left-right deviation of the gravity center of the whole machine can be controlled through left-right swing of the tail, meanwhile, rolling adjusting torque is generated and finally, attitude controllable flight with three degrees of freedom of pitching, rolling and yawing is realized.

Description

Technical field [0001] The present invention relates to the technical field of aircraft Micro, particularly relates to a bionic hovering aircraft Hummingbird and operation method. Background technique [0002] MAV refers to the volume less than 20cm, the flight distance is greater than 5km, and endurance capacity greater than the minor aircraft 15min. MAV has a small size, light weight, high concealment and flexible advantages, widely used in critical applications sensitive military reconnaissance, target acquisition, communications relay, and the like. Compared with rotary wing, fixed-wing type MAV, bionic flapping wing aircraft having a shape projecting the image of the advantages of low noise, capable of achieving excellent hiding performance. Further, when the aircraft is reduced geometry, small-scale aerodynamic properties of the rotor caused by a low Reynolds number, fixed wing aerodynamic efficiency is reduced, which results in rotary wing, fixed-wing aircraft difficult to...

Problems solved by technology

While changing the shape of the wing, this control method also makes the shape of the wing deviate from the ideal shape of the design, resulting in a decrease in lift, and the change in the aerodynamics of the wing adds unpredictable nonlinear characteristics to the dynamic characteristics of the wing system. It increases the difficulty of flight control of the aircraft, and may even cause the aircraft to lose control and fall
