A SYSTEM FRAMEWORK FOR DESIGN ROBUSTNESS ANALYSIS OF HELICOPTER MID-LIFE UPGRADES

摘要

The global budget climate has laid restrictions on the design and development of new military aircraft to meet the demands of enhanced mission capabilities. To enhance mission capabilities, mid-life upgrade of in-service aircraft, with state-of-the-art mission systems onboard, is acknowledged as a cost-effective option. To facilitate the mid-life upgrade process, a "Decision Support System" is required to identify the state-of-the-art mission systems that will provide the enhanced mission capabilities. In this paper, a brief outline of An "Integrated Decision Support System" (IDSS) framework developed by a systems approach to identify mission systems is presented initially, followed by a detailed discussion on the development of 'Design Robustness Analysis' (DRA) sub-model. The DRA sub-model automates the robustness analysis of aircraft upgrade design against 'temporal uncertainties factors'.
