Theoretical and experimental investigations concerning the viscous flow about airship bodies will be presented. Special emphasis is laid on the aerodynamics at high angles of attack or sideslip, where complex three-dimensional boundary-layer separation occurs. The flow separation has a decisive influence on the pressure distribution as well as on the load and moment distribution. The determination of the three-dimensional separation line is therefore of great importance. It will be shown that the separation line can be derived by means of three-dimensional boundary-layer computations without using empirical criteria. Calculations for the contour of the solar-powered airship 'Lotte' will be presented and compared with wind and water tunnel test results.
