Problems solved by technology

[0003] In fact, the Canadian orthopter that cannot take off and land on the spot is not a real orthopter; while the orthopter of Nanjing University of Aeronautics and Astronautics has extremely limited lift and a payload of only 38 grams; short
The reason is that the flapping wings that are fanned up and down will offset part of the lift force, which is inefficient; in addition, the reliability of the multi-link mechanism running at high speed will not be very high

Embodiment Construction

[0010] Preferred embodiments of the present invention are given below and described in conjunction with the accompanying drawings.

[0011] As shown in Fig. 1 and Fig. 2, the articulated-wing lift generating device is that two sets of assemblies with the same structure are axisymmetrically fixed together, and each set of assemblies consists of a drum 1, fins 2, hinge shaft 3, The fairing 4, the end plate 5, the bearing 6 and the rotating shaft 7 are composed. Among them, the drum 1 is a cylindrical cylinder with a hub at both ends, and the rotating shaft 7 that is longer than the cylinder is fixedly connected with the hub along the axis of the cylinder; 4 or 6 hinged shafts 3 are evenly distributed on the outer circumference of the drum 1, And be respectively fixedly connected with a generatrix edge of the arc-shaped fin 2 with wrapping angle of 90° or 60°; when the arc-shaped fin 2 is surrounded, it can tightly surround the drum 1, and when the drum 1 rotates Finally, the ar...

Abstract

The present invention relates to flapping wing aircraft, and is especially a hinged wing type lift force generator. The hinged wing type lift force generator includes two identical symmetrically connected assemblies, each of which consists of a drum wheel, arc wing panels, hinging shafts, a dome, an end plate, a bearing and a rotation shaft. After the drum wheel covered by the arc wing panels and on the rotation shaft rotates, the arc wing panels under the action of centrifugal force are stretched radially along the drum wheel to pull air downwards, so as to generate lift force. The present invention has efficiency higher than that of up and down moving flapping wing, structure simper than that of link rod mechanism, and reliable operation. The operation principle and structural form of the present invention may be applied in the ship propeller.

Description

technical field [0001] The utility model relates to an articulated-wing lift generating device, which belongs to the field of flapping-wing aircraft. Its principle and structural form can also be used as propellers for water vehicles. Background technique [0002] Human beings long to imitate birds to fly alone and freely in the sky, but they have realized their own flying desires in a different way—all effective flying machines do not have flapping wings (flapping wings) like birds, but Developed based on the constantly improving "wing theory". The history of human research on "bionic flight" is full of hardships and failures, and some people assert that it is impossible for human beings to fly with the help of flapping wings. Despite this, modern people who have overcome various technological difficulties are still unwilling to give up "bionic flight". In their view, only the flight of birds is personalized, and it does not need modern airports, long and solid runways, ...
