Abstract

The invention relates to an actively deformed stressed-skin structure, in particular to an actively deformed stressed-skin structure based on pneumatic muscles, which solves the problems that the existing stressed-skin material or structure deformation is passive and a complex mechanical transmission mechanism or drive mechanism is collocated in a deformed aerofoil to cause complex structure, heavy weight, large cost and the like. A plurality of pneumatic muscle fibers are arranged in parallel and plugged in a flexible basal body; the front ends of a plurality of pneumatic muscle fibers and the front end of the flexible basal body are connected with a first connection portion; the rear end of the pneumatic muscle fibers and the rear end of the flexible basal body are connected with a second connection portion; each pneumatic muscle fiber comprises a rubber capsule and a woven mesh cylinder for shape preservation; and the woven mesh cylinder for shape preservation is sleeved on the rubber capsule. Compared with the scale lamination or flexible stressed-skin materials, which are widely used today, the structure provided by the invention has the advantages of simple drive structure, light weight, integrated drive / deformation / load bearing and the like.

Description

technical field [0001] The invention specifically relates to an actively deformable skin structure, which belongs to the technical field of deformable aircraft. Background technique [0002] Deformable aircraft technology has become a research hotspot in today's aviation field, and deformable skin technology is undoubtedly one of the most critical technologies. At present, there are three main types of deformable skins used in research on deformable aircraft. The first type is rubber-like materials with a large elastic range, and the deformation function of the skin can be realized through the elastic deformation of the material itself; the second type is the skin structure that realizes deformation through a sliding or rotating mechanism, such as "fish scale lamination". "Deformable skin; the last category is the skin structure composed of deformable structure and silicone rubber material, such as deformable honeycomb and corrugated plate. All in all, the existing skin ma...
