Flapping wing mechanism with controllable pitch angle of left and right wings and manual flapping wing machine

Abstract

The invention relates to a flapping wing mechanism with controllable pitch angle of left and right wings and a manual flapping wing machine. The flapping wing machine comprises a left wing, a right wing, wing shaft assembly pipes, an upper cross beam of a machine frame, a bottom rod of the machine frame, left and right side rods of the machine frame, a manual pulling handle, a pitch angle handwheel, a pedal rod, a left wheel, a right wheel, a left suspension cable main cable, a right suspension cable main cable, a left suspension cable, a right suspension cable and other related settings. Theflapping wing mechanism further comprehensively applies the flapping wing pitch self-adjustment, machine body roll-over and machine body pitch control system. When a human body lifts and crouches, hands and feet exert force together, so that the wings automatically generate periodic motions of downward flapping at a depression angle and upward sliding at an elevation angle, and at the same time, complex motions of rolling, climbing and subduction can be superimposed, and thus completely controllable flight of the human flapping wing machine is realized. Compared with the prior art, the flapping wing mechanism has comprehensive application, has the characteristics of optimized structure, light weight, flexible operation and convenient take-off and landing, is suitable for outdoor competitive activities and the like, and has a certain development prospect.

Description

technical field [0001] The invention belongs to the field of aviation vehicles and aircraft mechanisms, and in particular relates to a flapping mechanism with controllable pitch and pitch angles of left and right wings and a human-powered flapping airplane. Background technique [0002] On the flapping wing aircraft, there are many successful reports and patents all over the world. But in the aspect of manpower flapping wing aircraft research, there is no relatively successful report at present. [0003] In terms of fixed-wing human-powered flight, according to Science Network (kexue.com), the world record for long-distance flight of a human-powered aircraft is 115.11 kilometers created by the Massachusetts Institute of Technology in 1988. The net weight of the world-record "Daedalus" 70 pounds (about 31 kilograms), the whole journey took 3 hours and 54 minutes, and the speed was 29.5 kilometers per hour. At present, this record has not been broken. [0004] According to n...

The superficial understanding refers to people’s understanding of the wings and body of birds, a pair of interdependent contradictory subjects such as lift and load, which superficially explains the basic movements of flapping wings. There are many ideas, but most of them ignore it. The most basic scientific method of mechanical analysis
