Problems solved by technology
That is to say, two transmission components are used to respectively drive the two pairs of wing membranes on the left and right. The structure is more complicated, resulting in a larger overall volume of the flapping wing aircraft, and a lower degree of miniaturization, which makes the overall volume and weight of the flapping wing aircraft larger.
However, if the volume and weight cannot be optimized, it will affect the battery life of the machine.
The structural asymmetry of the flapping-wing aircraft with the above-mentioned structure will also lead to a more complex physical force model, which affects the controllability of the aircraft to a certain extent

The invention discloses a hovering flapping-wing air vehicle based on a single-crank double-rocker mechanism. The flapping-wing air vehicle comprises a rack, two power mechanisms which are symmetrically arranged left and right, two planetary reducers, two digital steering engines, two driving motors and a foot support frame. According to the flapping-wing air vehicle, the single-crank double-rocker mechanism is used as a driving flapping wing executing mechanism with the Wei s-Fogh effect, the planetary reducer mechanism which is integrally designed is used for achieving speed reduction and torque increasing of driving motors, and two digital steering engines are used for adjusting the flapping angle of a wing film through a driving rotating rod to achieve maneuverability of the flapping-wing air vehicle; the four controllable parameters of the flapping-wing air vehicle are the rotating speeds of the left and right driving motors and the steering quantities of the left and right digital steering engines respectively, and the flapping-wing air vehicle is simple in structure, high in micro degree, symmetrical in structure, simple in stress model and good in controllability.
Description
technical field [0001] The invention relates to an aircraft, in particular to a flapping-wing aircraft with a single crank and double rocker mechanism. Background technique [0002] Most of the existing vertical take-off and landing bionic flapping-wing robots adopt the external gear reduction scheme, and the two wing membranes are driven to fan in opposite or opposite directions through a double-crank and double-rocker mechanism. That is to say, two transmission components are used to respectively drive the two pairs of wing membranes on the left and right to move. The structure is more complicated, resulting in a larger overall volume of the flapping wing aircraft, and a lower degree of miniaturization, which makes the volume and weight of the whole machine larger. However, if the volume and weight cannot be optimized, it will affect the battery life of the machine. The structural asymmetry of the flapping-wing aircraft with the above-mentioned structure will also lead to...
