Abstract : Crashworthiness activities at MBB data back to the late sixties, when during BO 105 development crash protection systems such as seats, fuel systems, and landing gears were developed which are integrated in the military versions of the BO 105 for the German Army. In February 1974 a BO 105 was crash tested to show compliance with the Crash Survival Design Guide (TR 71-22) under an impact condition of 15 m/s longitudinal and 8 m/s vertical velocity. Effective design tools, both in house and at subcontractors and experience with helicopters in service are used at MBB to contribute significantly to fulfill the crash requirements in European helicopter programmes and in joint developments with foreign partners. Although crash protection techniques and crashworthiness prediction methods are already fairly well established, there remain still a lot of tasks, mainly when using advanced materials and in improving the analytical methods from an economic point of view.
