Linkage hollowed-out wing unit suitable for flapping-wing air vehicle

Abstract

The invention discloses a linkage hollowed-out wing unit suitable for a flapping-wing air vehicle. The linkage hollowed-out wing unit suitable for the flapping-wing air vehicle comprises a rack, a driving device, a linkage device and a plurality of rotary wings which are sequentially arranged at intervals. The linkage device comprises a rocker, a reversing gear component, a gear connecting rod, a transmission gear and a vertically-mounted transmission rod. The designed wing unit is formed by arranging the multiple rotary wings at intervals, and the assembled wing unit is of a hollowed-out structure, so that when the air vehicle takes off, the contact area between the wing unit and air is small, the rising resistance borne by the air vehicle is small, the air vehicle can take off rapidly, and the flight efficiency is high; in addition, the wing unit is folded or unfolded through linkage control so that the flapping-wing air vehicle can obtain the optimal performance in different flight states; furthermore, the linkage device is adopted for synchronous deformation of the wing unit, the synchronization rate of deformation is high, and linkage control is stable and accurate; and the linkage hollowed-out wing unit is extremely suitable for the flapping-wing air vehicle of a small structure.

Description

technical field [0001] The invention relates to an auxiliary part of an aircraft, in particular to a linked hollowed-out wing suitable for a flapping-wing aircraft. Background technique [0002] The human flying dream started from the flapping wing aircraft, and the most primitive wing structure is fixed. At present, fixed-wing aircraft and propeller helicopters can fly at high altitudes around the world, but flapping-wing aircraft are still struggling. One of the main problems is that flapping makes the resistance greater as the area of ​​the wings expands. Therefore, it is particularly important to change the stress situation of the wing in the process of fluttering up and down. To solve this problem, various retractable / deformable wings have appeared. When they are working, they can generally change the shape of the wings according to the needs of navigation, so as to obtain the best performance in different flight states, thereby improving the multi-environment and mul...

AI Technical Summary

Problems solved by technology

However, the retractable wing of its design is heavy and bulky, and has the following defects:

[0004] 1) When the overweight wing is fluttering upwards, the area of ​​the wing in contact with the air is large, and the rising resistance received is large, which makes the take-off time of the aircraft long and the flight efficiency low;

[0005] 2) When the wing structure used is deformed, linkage control cannot be achieved, and the synchronization of deformation is low
