Projected cargo airships for the flexible transport of large loads exceed the dimensions of existing aircrafts and gave rise to various technical problems. In order to study the dynamics of the load exchange process mathematical models of the airship including the oscillating load frame are developed. The hull and the load frame are represented by a multibody system. Crucial aspects contributing to the system's dynamics are the floatation of the flying crane and nonlinear couplings between hull and load frame. Furthermore, added masses of the surrounding air are considered. Oscillations of the load frame are excited by wind loads, airship maneuvers, and winding up the cables.
