Crash loads must be attenuated in the landing gear, the subfloor structure, and the seat to values tolerable for the human body. In addition the remaining loads must not jeopardize a living space for the occupants. A program was undertaken to investigate, both analytically and experimentally, the crushing behavior of helicopter subfloor structures. Stiffened panels and honeycomb sandwich panels in metal were considered under quasistatic and dynamic conditions. The primary intent of the investigations was to design subfloor structures with high efficiency for crash impact and to establish the nonlinear characteristics of subfloor structures as input data for the program KRASH.
