A metal airframe of an aircraft of the weight class 3T was investigated in crash cases with a mainly vertical impact component using the simulation program KRASH 79. The results of the simulation calculations are shown in the form of acceleration/time evolutions of the discretized masses of the idealized structure and of structural displacements in the frame. The deformation behavior of a given seat structure was determined, and the dynamic-response index allows one to predict back injuries. Configuration-typical force/displacement characteristics under axial pressure loading were obtained in dimensionless form, allowing the determination of the dynamic response of the airframe.
