Bionic morphing wing of water-air amphibious aircraft and diving control method of bionic morphing wing

Abstract

The invention discloses a bionic morphing wing of a water-air amphibious aircraft and a diving control method of the bionic morphing wing. The bionic morphing wing of the water-air amphibious aircraft comprises a primary wing body, a secondary wing body, a primary controllable telescopic mechanism, a secondary controllable telescopic mechanism, a controllable rotating mechanism, folding skin, a fuselage and a control and driving system in the fuselage. One end of the leading edge of the primary wing body is connected with the controllable rotating mechanism through a hinge, and the other end of the leading edge of the primary wing body is connected with the secondary wing body through a hinge. One end of the primary controllable telescopic mechanism is fixed in the primary wing body, and the other end of the primary controllable telescopic mechanism is installed in a slideway on the surface of the controllable rotating mechanism through a pin. One end of the secondary controllable telescopic mechanism is fixed in the primary wing body, and the other end of the secondary controllable telescopic mechanism is installed in a slideway on the end face of the secondary wing body through a pin. The wing surface of the primary wing body and the wing surface of the secondary wing body are sewn through the folding skin, and the wing surface of the primary wing body and the fuselage are also sewn through the folding skin. The bionic morphing wing of the water-air amphibious aircraft and the diving control method of the bionic morphing wing can meet the requirements for conventional flying in air and rapid pitch-down diving of trans-medium aircrafts, and the effects that the diving process of the aircraft is stable and the water resistance and impact are reduced are guaranteed.

Description

technical field [0001] The invention relates to a wing of a water-air amphibious aircraft, in particular to a deformed wing of a water-air vehicle and a control strategy for the wing during the water entry process of the aircraft. Background technique [0002] The water-air amphibious vehicle is a new-concept cross-media vehicle that moves between air and water. It is a multi-functional integrated new equipment that can fly in the air and dive underwater. It can switch the water and air operation mode to avoid the enemy's surveillance and realize stealth combat in an unconventional way. It can be used to perform military tasks such as intelligence collection, maritime reconnaissance, communication relay, electronic countermeasures, and marine anti-terrorism, as well as civilian tasks such as marine resource exploration, meteorological measurement, and ecosystem detection. [0003] Research on water-air amphibious vehicles at home and abroad is still in the stage of overall ...

AI Technical Summary

Problems solved by technology

At present, most of the control strategies for the water-air amphibious vehicle entering the water are to lower the flying height to fly close to the water surface, and then slowly dive underwater by changing the buoyancy and other methods. Therefore, it takes a relatively long time for the vehicle to completely enter the water from the air, so , a new technology solution to realize the fast and efficient crossing of different media interfaces by mass aircraft is yet to be proposed
