Bionic flapping wing aircraft based on difference frequency and offset amplitude

Abstract

The invention belongs to the technical field of manufacturing of bionic flapping wing equipment and particularly relates to a bionic flapping wing aircraft based on difference frequency and offset amplitude. A main structure of the aircraft comprises five members including a wing assembly frame, a ventral tail module, a front wing assembly, a rear wing assembly and a head module, wherein the ventral tail module, the front wing assembly, the rear wing assembly, the head module and the wing assembly frame are assembled and jointed into a whole part; the wing assembly frame is connected with thefront wing assembly through an outer bevel bar and an inner bevel bar; the front wing assembly is connected with an inner front support rod pin of the ventral tail module through a first external rotating rod to realize the connection of the front wing assembly and the ventral tail module; the front wing assembly is connected with the rear wing assembly through a lower lifting rod; multi-stage series-connection rods of the ventral tail module can realize longitudinal bending maneuvering of a machine position and improve the performance of coping with variable air flow loads; a bending processis smooth, and the adjustment flexibility is high; the joint fitting property of an evolution rod assembly is more efficient than that of a gear and friction limiting swing mechanism, and the physicalloss of components is reduced. The aircraft has the advantages of simple main body structure, ingenious design concept, friendly application environment and broad market prospect.

Description

Technical field: [0001] The invention belongs to the technical field of bionic flapping-wing equipment manufacturing, and in particular relates to a bionic flapping-wing aircraft based on difference frequency and amplitude. Background technique: [0002] Dragonflies are one of the creatures with the best flight performance in nature, capable of flying upside down, flying sideways, gliding and even hovering in the air. The unique flying ability of dragonflies comes from its well-developed wing muscles and air sacs. The wing muscles can quickly inflame the wings and adjust the flight angle. The air sacs store air, which can regulate temperature and increase buoyancy. Dragonflies rely on their own unique nervous system to adjust the flight angle and control the beating frequency, which can not only generate upward lift, but also have forward or backward thrust to achieve free flight. [0003] Since ancient times, nature has been the source of various technical ideas, engineeri...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the disadvantages of single swing amplitude, large traveling inertia and low frequency state fitting degree that most of the existing mechanisms use primary connecting rods, etc., and seek to design a new type of bionic flutter based on difference frequency and wrong amplitude. Wing aircraft, the flight mechanism reduces the inertia of the operation through the parallel multi-stage loop mechanism, the two-way difference frequency location design, effectively utilizes the linear transmission of the evolved core rod group, improves the travel speed, and completes the protoplasmic reproduction of the behavior at the same time
