Abstract

In the conceptual design of aircraft jet engine components, not only the product architecture and dimensions are set but the associate manufacturing processes are also defined. From a design decision point of view it is critical to identify and characterize the consequences of alternative solutions. This paper reports on a case, where a milling process needed to be selected in an early design phase of a jet engine component. An Electro-Chemical Milling process was considered but its impact on sustainability needed clarification.

An approach that combined a simplified Environmental Impact Assessment with a Strategic Sustainability Assessment was used. The main finding and contribution from the work is a method that helps to clarify consequences of sustainability-related issues by combining the two analysis tools with a risk analysis implementation. The results reveal that once the consequences can be clarified, increased attention and understanding are gained.
