Transformable inflatable extensible wing driven by piezoelectric fiber composite material

Abstract

The invention provides a transformable inflatable extensible wing driven by a piezoelectric fiber composite material and belongs to the technical field of inflatable extensible wings. The transformable inflatable extensible wing comprises an inflatable wing and a driving element, wherein the inflatable wing comprises a skin and a brace; the driving element comprises a substrate and a piezoelectric fiber composite material; the substrate is shaped like a rectangle which is bent into an arc surface; the piezoelectric fiber composite material is adhered to the concave surface of the substrate; and the convex surface of the substrate is adhered to the inner wall of the skin. The invention provides a scheme of driving the inflatable extensible wing by employing the piezoelectric fiber composite material, the piezoelectric fiber composite material and the concave surface of the substrate are adhered to form the driving element, and the driving element is adhered to the inner wall of the skin of the inflatable wing. The driving characteristics of the piezoelectric fiber composite material are utilized, and the inflatable wing can be driven to deform, so that the problem that the pneumatic efficiency of the inflatable extensible wing can not be optimized is solved. The inflatable extensible wing is simple in structure, high in integrity and stable in operation, and a driver is convenient to manufacture and easy to arrange and mount.

Description

technical field [0001] The invention relates to a deformable inflatable and stretchable wing driven by a piezoelectric fiber composite material, belonging to the technical field of inflatable and stretchable wings. Background technique [0002] Wings are the main components that are integral to every aircraft to generate lift. It is usually divided into two left and right airfoils, which are symmetrically arranged on both sides of the fuselage. Some parts of the wing (mainly the leading and trailing edges) are movable. By manipulating these parts, the pilot can change the shape of the wing and control the distribution of lift or drag of the wing, so as to increase the lift or change the attitude of the aircraft. However, many of the special functions of wings in flight are often useless when the ground is stationary. For example, because of its existence, it requires a large area of ​​apron, a hangar with a large space, and a large radius when taxiing and turning on the r...

Problems solved by technology

[0006] However, there is an important shortcoming in the inflatable stretchable wing, that is, it is difficult to arrange control components such as flaps, ailerons, and spoilers on it.

Therefore, it is difficult for the inflatable stretchable wing to change the characteristics of the wing according to the flight conditions during flight, and the aerodynamic efficiency of the aircraft wing cannot be optimized.
