The R search on Aircraft Economic D egn

Economics affordability like safety, reliability, maintainability, is the inherent attributes of aircraft. Total life cost is the main economic index for aircraft. Active economic design for aircraft shows cost as independent variable. And economic design should consider total cost throughout the product development including design, manufacture, use and maintenance. In the paper, the multilevel modular analysis model on total life cycle cost has been presented. The main dimension of aircraft economics design has been analyzed, including pneumatic design, composite materials design and oriented-maintenance design. Combination prediction model of life cycle cost for aircraft with fuzzy and uncertain information has been built. The aircraft economics design by collaborative optimization has been presented by multidisciplinary optimization. The aircraft integrated economics design has been discussed, including the framework and relevant technology of aircraft integrated design. The research result can also be used to other complex systems, such as weapon systems.
