THE ROLE OF MDO WITHIN AEROSPACE DESIGN AND PROGRESS TOWARDS AN MDO CAPABILITY

This paper reviews recent progress made in MDO within the European aerospace industry through the activities of a sequence of international collaborative partnerships of increasing complexity. Firstly, a definition of MDO is provided and its function as a key tool in the context of concurrent engineering is discussed. Issues addressed include the limited support given by many MDO tools to detail stressing, validation of aeroelastic optimisation, the role of product models, the definition and execution of MDO process under user control and trade-off studies for requirement capture. The need for the adoption of standards in the definition of the product model and the likely impact of the CALS philosophy of 'create data once and use many times' are highlighted.
