The aerodynamic forces acting on an airship placed in a turbulence flow field inside the UTIAS boundary layer wind tunnel were measured. This provided a data base upon which theoretical simulation of the airship's response to turbulence could be evaluated. The slender body theory, as used in this report, has failed to predict the behavior of a bare airship hull in turbulence. An extended three-dimensional slender body theory is also included. Although slightly better predictions were obtained, the extended theory is still far from providing accurate simulation. In general the slender body theory is an extremely conservative means of evaluating modern airship behavior in atmospheric turbulence. The method of simulation should be reevaluated.
