Combined design and analysis of durability and damage tolerance for flight structure

Based on existing durability and damage tolerance analysis method, the 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 was given. Besides of using life and safety analyses, structural weight and the inspection and maintenance were discussed. It can be used to increase the maneuverability and economy of the flight structure. A calculation example was presented to validate the feasibility of this method.
