Risk management for conceptual evaluation of jet engine structural components
2003 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

This work completes the final part of mechanical engineering machine design at Luleå University of Technology. It has been performed during the spring and summer 2003 at Volvo Aero Corporation in Trollhättan, Sweden. The main objective and overall scope is to develop a risk management plan connected to the Intermediate Compressor Case (ICC) specific requirements and apply it to two concept design solutions. The methodology is developed with focus on project related cost drivers as component cost, lead time and weight. The methodology originates from design demands of a cold jet engine structure (ICC) and identifies important requirements at the first concept stage. These lead to delivery objects, solution, and planning for the project to proceed. Also, risks in main areas of the product development have been quantified and connected to the design demands in order to give a logical structure from definition of design requirements to delivery object whilst considering and mitigating all corresponding risks. In co-operation with experienced people at Volvo Aero Corporation (VAC) and using earlier projects as a starting point: specifications, interviews and literature studies of important areas serve as a basis for this methodology. Important aspects to consider in developing and manufacturing a product are collected during the initial phase. These experiences can have a serious impact in starting a new project. The application of the methodology on two conceptual solutions at the end of the thesis gives a good example of how the methodology can be applied. The results from this analysis show that one of the concepts has more top risks, mainly in the manufacturing, engine life and component functionality area. This gives an example of where mitigation is required. Also, after every project is completed it is good practice to review the lessons learned and demands identified. This will help on future projects to identify demands, and hence risks at an early stage and ensure a more effective design and development process.
