'Movable pendulum arm' and flapping-wing aircraft

Abstract

The invention is a mechanical flapping wing flying device similar to the flying of birds and insects. The swing fulcrum a on the two driving rods is constrained on the horizontal slide rod outside the casing, the two circular trajectory points m are constrained in the inner ring groove of the casing, and the two linear trajectory points b are connected in parallel; the fixed point G on the two zoom wings is connected to the two driving rods The upper corresponding points are hinged, and the upper zoom point S of the two zoom wings is hinged with the end holes outside the staggered racks in the side slots of the two drive rods; when the drive pin is stuck, the power is input from the parallel connection to drive the wings to flutter. During the double-wing flight, the angle of the flapping wings can be changed at any time or the wings can be locked at will, and the conversion is fast and reliable. The wings can be equipped with a zoom-wing mechanism that alternately bends up and down. When the wings flap, the inertial impact at the turn-back point has double crank rollers. The mechanism absorbs and any point on the wings has alternating changes of gradual acceleration and gradual deceleration, so the flying posture is beautiful and natural. There are monoplanes and biplanes, and a variety of fixed and zooming wings. It can develop popular manned flapping-wing aircraft and unmanned flapping-wing aircraft for various purposes.

Description

(1) Technical field: [0001] The invention is a mechanical flapping-wing flying device similar to the flying of birds and insects, which develops popular manned flapping-wing aircraft and unmanned flapping-wing aircraft for various purposes. (two) background technology: [0002] Birds and insects in nature are perfect, and their superb flapping wings will always attract and challenge people. The flapping wings driven by multiple pulley blocks driven by human power and tied to the ropes described by the versatile Da Vinci 500 years ago clearly express the long-standing desire of human beings to fly, which has been realized by various modern aircraft. However, what is also puzzling is why there is no manned flapping wing aircraft flying in the sky so far? As far as the current level of science and technology is concerned, there are no insurmountable difficulties in terms of power, materials, control, processing technology, aerodynamics, etc., only the lack of practical flappin...

However, what is also puzzling is why there is no manned flapping wing aircraft flying in the sky so far? As far as the current level of science and technology is concerned, there are no insurmountable difficulties in terms of power, materials, control, processing technology, aerodynamics, etc., only the lack of practical flapping wing flying devices may hinder the development of flapping wing aircraft one of the reasons
