Kurzfassung in Deutsch

Additive layer manufacturing (ALM) is the process of adding material layer by layer to form parts and products. It has gained a lot of popularity and has now been used by aerospace industry giants to manufacture aircraft parts which are much lighter and cleaner in terms of energy and carbon emission.This thesis presents an analytical and experimental study of the behavior of rocker arm and axle of DA62, which form a part of the assembly of the whole Main Landing Gear (MLG). The way these parts behave and deform under loads is analyzed. Six load cases are provided during the drop test, among which the critical load case is recognized via FE analysis. This information is then used to perform topological optimization. The aim of this study is to perform optimization for weight reduction. In conjugation with that, the optimization has to be performed for ALM. Using these six cases, optimized results are obtained. A CAD model is again developed to suit the requirements and design rules pertaining to ALM. This CAD model is used for FE reanalysis. A few iterations are performed with optimization and CAD modelling to finalize a working model. Hyperworks and CATIA are used extensively for this project.The second part of the thesis is a study about identifying other aircraft parts that are or can be manufactured using ALM and what criterion are used in doing so.
