Abstract

The invention provides a deformable wing and an aircraft. The deformable wing comprises a non-deformable main body and a deformable trailing edge flap connected with the non-deformable main body, thetrailing edge flap is provided with an upper skin and a lower skin, at least one of the upper skin and the lower skin is a multi-stable skin with a plurality of bistable areas, the bistable areas cankeep two stable forms, the trailing edge flap can keep multiple stable shapes through multiple form combinations of the bistable areas of the multi-stable skin, and the shape of the trailing edge flapcan be changed among the multiple stable shapes by controlling form conversion of all the bistable areas of the multi-stable skin. The aircraft includes the deformable wing. The wing can maintain various wing sections, can bear large air loads, can adapt to various flight conditions, and improves the flight performance of an aircraft.

Description

technical field [0001] The invention relates to the technical field of aerospace, in particular to a deformable wing and an aircraft. Background technique [0002] Since the invention of simple aircraft by the Carter Brothers, man-made aircraft have been widely used in military and civilian fields. Man-made aircraft of various shapes and sizes have been continuously invented and improved according to different needs. The aircraft needs to go through multiple flight stages when performing tasks, such as take-off, climbing, cruising, circling, landing, etc. In different flight stages, its flight environment (such as altitude, speed, climate, etc.) will also change accordingly, so the aircraft needs Adjust the configuration to achieve efficient, safe and reliable flight status, and complete the corresponding tasks. At present, the aircraft mainly relies on fixed wings and propeller rotation to obtain continuous lift to overcome gravity and keep the aircraft in flight. Mechani...
