Crashworthiness activities at MBB date 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. Since the mid-seventies theoretical studies were conducted with the aide of the computer program KRASH and nonlinear finite element codes, supported by the German Ministry of Defence, and partly verified by component tests. The experience with the crash behavior of the BO 105 was successfully used for the development of the BK 117 which was shown by a full-scale crash test, conducted in 1985 by Kawasaki, MMB's partner in the BK 117 development. 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 programs and in joint development with foreign partners. Although crash protection techniques and crashworthiness prediction methods are already fairly well established, there still remains a lot of tasks, mainly when using advanced materials and in improving the analytical methods from an economic point of view.
