Structural design and testing of composite wing high-lift device

Abstract

A problem for designing aviation structures made of sandwich-like polymer composite materials has been examined based on the example of a typical device for mechanizing a wing-spoiler. The spoiler’s loading pattern is chosen according to topological optimization. A way to determine the orientation, number, and proper order of layers laying has been examined as a problem of discrete optimization by using different algorithms. The peculiarities of layered structure simulation have been discussed. Tests results for spoiler have been presented and they verify the design and technological solutions.
