Abstract�� Based on existing durability and damage tolerance analysis method, a new way of flight structure design and analysis by synthesis was presented. It solves the problem that designing with durability or damage tolerance method separately will affect the optimization design for the flight structure. The analysis flowchart of this method is also given. Besides of using life and safety analyzing, structural weight and the inspection and maintenance were discussed. It can be used to increase the maneuverability and economy of the new flight structure. In addition, a calculation example is presented to validate the feasibility of this new method.
Keywords�� synthesis   reliability   durability design   damage tolerance design
