Designing for a Crashworthy All‐Composite Helicopter Fuselage
Abstract:The helicopter fuselage should be designed to protect the occupants in a crash‐impacf environment. In the design of a composite fuselage, the energy absorbing features of structural elements which constitute the fuselage are material, shape, and type of construction. The failure mode, predetermined through material selection, design and method of construction, and the element shape, when optimized for ply orientation and geometry, can enhance the energy absorbing capacity of structural elements. This paper identifies the crashworthiness design parameters and presents a building‐block approach in developing crashworthiness design data of composite materials and design features of structural elements. The data are generated from results of quasi‐static and dynamic tests and provide a guide to the comparative influences of crashworthiness parameters in the design of composite structural elements of a helicopter fuselage.
