| Summary: | The aircraft structures combat survivability is one of the critical factors,which affect the integration combat efficiency of aircraft.The efficient design of aircraft structures survivability is of great significance to improve the combat ability,decrease the expenses in service,and ensure the well combat readiness of aircraft.At first,the design factors of aircraft structures combat survivability,based on the connotation of survivability and the design requirement of structures survivability for aircraft are combed.Then the design guidelines of aircraft structures combat survivability are discussed.Finally,the design and analysis methods of aircraft structures survivability are presented,under the effects of explosions-overpressure field and gust field,which are the two different aspects of blast wave.The analysis example is presented.Results show that the design factors of aircraft structures combat survivability are similar to the damage tolerance design,and the design process of damage tolerance could be used in structures combat survivability design.The fuselage panel,leading edge,moveable surface and cover,which are sensitive to overpressure of blast wave,can be designed to improve structure survivability by configuration optimization.
