Abstract

The paper has been intended to provide several examples to illustrate how the reverse-engineering method is applied to the process of extending service lives of aircraft in operation with the Polish Armed Forces. The exemplary issues of concern are: evaluation of stress in the structure after modification, estimation of how failures (corrosion) affect the stress distribution, and estimation of fatigue life. Numerical calculations were carried out using the finite element method (FEM). To build a computer model, a manually operated scanner 3D or a photogrammetric method were used.

Keywords: Reverse engineering, aircraft, FEM
