The extensive use of composite materials in helicopter structures has prompted research activities in crashworthiness in the last decade. A rational design of crashworthy structures requires a great deal of data and experience to be collected and organized; in particular the most efficient mechanisms of energy absorption must be understood and carefully investigated and consequently the best structural concepts and detail design can be identified. With this aim and in cooperation with Agusta Helicopters a research program was undertaken, covering many of the basic aspects of crashworthy design, i.e., dynamic experimentation on subcomponents and subassemblies, hybrid and true finite element modeling, design, and verification procedures. The paper presents some preliminary results, together with the outline of the whole program.
