Abstract : For the BK 117 helicopter a composite fuselage was designed, manufactured, and will be flight tested at MBB. Within the development programme evidence was given to the crashworthy design of the fuselage which was accomplished by a joint activity between MBB and DFVLR Stuttgart. The crash investigations were focused on the lower airframe section under vertical crash loads. The task was performed by design support tests on the specimen level and by sub-component crush testing. Sandwich panel specimens were statically and dynamically crushed to study various crush initiators at the panel-skin intersections, and to investigate the energy absorption capability. (JES)
