Numerical Analysis of the Impact of Geometric Parameters of the Outcuts in the Wing Torsion Box Wall on the Mechanical Properties of the Structure

Abstract

The study presents the results of comprehensive numerical analyses of an unusual solution in the field of geometry of holes in the wall of the wing torsion box subjected to torsion. Due to the nature of loads acting on the wing structure in flight conditions, it is possible to modify the current standard solutions. However, this involves a fundamental change in the nature of stress distribution and the resulting need to use new types of local reinforcements of the structure. The analyses were supposed to indicate the dependencies between the geometric parameters of the outcuts and the nature of advanced deformations and the distribution of internal forces.
