Deformable skin structure with designable poisson ratio

Abstract

The invention relates to a wing skin structure, in particular to a deformable skin structure with a designable poisson ratio, aiming at solving the problem that the existing skin structure cannot meet the requirements of lower deformation rigidity along the deformation direction and higher structural rigidity along other non-deformation directions, thus being not capable of bearing aerodynamic load and inertia load. The deformable skin structure comprises a honeycomb structure base body, a flexible elastomer and a plurality of pneumatic artificial muscles, wherein the honeycomb structure base body is a honeycomb structure body formed by arranging positive poisson ratio honeycomb unit bodies and negative poisson ratio honeycomb unit bodies in a mixed way; the flexible elastomer is poured onto the honeycomb structure base body and the plurality of pneumatic artificial muscles so as to form a flexible panel. The deformable skin structure with the designable poisson ratio is used for manufacturing aircraft wing skin.

Description

technical field [0001] The invention relates to a wing skin structure, in particular to a wing skin structure of a water-air amphibious aircraft, which belongs to the technical field of aircraft. Background technique [0002] Whether it is a flying animal or an artificial aircraft, in order to perform different tasks (such as cruise, hover, attack or escape, etc.), or to meet the different requirements of the flight environment (such as altitude, speed and climate, etc.), it often needs to be adjusted accordingly. To achieve high efficiency, safety and mission requirements. [0003] The deformable aircraft can change its aerodynamic layout according to the external flight environment to achieve the purpose of optimal flight performance. The most important thing in the design of deformable aircraft is the design of the skin. In order to achieve the method of changing the structure with the minimum driving force, the skin structure or material needs to have low deformation s...
