Abstract [en]

This project belongs to one of three parts of a bigger project: the aim of the big one is to develop an automated routine which will do the mechanic analysis of a piece of an aircraft engine, such as the stress analysis, the displacement analysis, or the stiffness analysis, all of them by using FEA systems. This Master thesis project is a piece of study of a simplified turbofan jet engine, which will be called during the project “the whole engine model” (WEM). The project was done in collaboration with Volvo Aero which is a Swedish company that deals with aerospace business, specialized in structural jet commercial engines. The purpose of this labor is to try to make Volvo Aero’s product development activities more effective, by making the right things, and efficient by automating processes. In the general project, the aim of the model is to calculate some design parameters which need to be optimized, as they can be, for instance, the relation among the tip clearance, the hole radius and the fan radius: in order to get a maximum power by reducing the tip clearance surface, but with enough security to assure that there won’t be contact between the fan and the case. Other parameters such as the optimal length of the bearing will be discussed and calculated also. The specific goal within this Master’s thesis project is to develop a model, with its geometric features added with rules.
