Title Strength analysis of composite wing glider
Abstract
As technology increasingly update, we consider not only limited aspects of the structure of the missile wing, but concerned about in terms of its materials, the rise of composite materials for the development of gliding brings more possibilities. Composite materials are light weight, stiffness and strength characteristics, as well as high fatigue strength, high shock resistance characteristics. Composite wing is the future direction of the glider research, we must first carry out the strength of the composite material wing stiffness analysis, in order to carry out further research. In this paper, ANSYS software for composite wing finite element mesh partition and using composites symmetrical layer and the plate, carbon fiber wing glider under static conditions, for four kinds of composite ply comparative study ways to give stress and deformation of the different contours of each wing of the overlay mode, comparative study wing stiffness and strength.
