Problems solved by technology
[0003] In the prior art, the active twisting mechanism of the wing mainly adopts the form of installing a motor in the wing to directly twist the wing. The advantage of this is that the twisting can be controlled artificially, but the number of control motors is increased, and the structural weight of the wing is increased. And this type of torsion mode can bring about a large torque change with a small change in the wing load, but because the structural weight limits the power of the motor, the motor cannot withstand a large torque, resulting in a small rated wing load of the flapping wing

Embodiment
[0028] The outer section wing 2 is connected with the connecting block A6 and the connecting rod D10 by a flexible material with a certain rigidity support as a whole, and the connecting rod A5 and the connecting block A6 are connected with a connecting rod driving mechanism.
[0029] The driving device drives the connecting rod A5 to drive the connecting block A6 to rotate around the hinge A3, thereby driving the connecting rod B7 to rotate, and the connecting rod B7 drives the front end of the outer section wing 2 to flutter relative to the inner section wing 1, such as image 3 shown;
[0030] The driving device drives the connecting rod C8 to drive the connecting block B9 to rotate around the hinge B4, thereby driving the connecting rod D10 to rotate, and the connecting rod D10 drives the rear end of the outer section wing 2 to flutter relative to the inner section wing 1, such as Figure 4 shown.
[0031] By changing the phase difference between the connecting rod A5 and...

The invention discloses an active wing torsion mechanism driven by a connecting rod mechanism, which comprises an inner section wing, an outer section wing, a hinge A and a hinge B which are used for connecting the inner section wing and the outer section wing, and a connecting rod A and a connecting rod C which are positioned in the inner section wing are fixedly connected with a connecting rod B and a connecting rod D which are positioned in the outer section wing through a connecting block A and a connecting block B respectively, and the connecting block A and the connecting block B are respectively mounted on the hinge A and the hinge B. The torsion mechanism can bear a large torque, so that a high wing load is borne, the thrust is increased, the flight resistance is reduced, and the cruising ability is improved.
Description
technical field [0001] The invention relates to the field of aircraft, in particular to an active wing torsion mechanism driven by a link mechanism. Background technique [0002] Humans have long had the ideal of flying like birds in the air. The mechanical pigeons made by Arcytas in ancient Greece, the boomers as far away as Australia, the Kongming lanterns and kites in China are all related. The development of modern aircraft has benefited from the huge leaps in science and technology brought about by the Industrial Revolution in the 19th century. The human dream of flying started with a flapping-wing aircraft and was initially realized with a fixed wing. At present, fixed-wing aircraft can send humans to the blue sky, but the dream of flapping wings is still in progress. The twisting of the wings during the flight of the aircraft can increase the thrust, improve the lift-to-drag ratio, improve the endurance performance of the aircraft, and also strengthen the roll contr...
