AN INVESTIGATION OF THE EFFECTS OF INDUCED NONSYMMETRIC PRESSURE DISTRIBUTIONS ON THE AERODYNAMIC STABILITY OF AN AIRSHIP FORM

Abstract

Installations which would induce nonsymmetric pressure distributions about the airship hull or create high off-center drag forces were suggested for evaluation as possible control devices for the finless airship. Inflatable, compartmented rings or bulges, and extensible spoilers are examples of the type of devices considered worthy of investigation. The results of a study of the effects of induced nonsymmetric pressure distributions on the aerodynamic stability of an airship model are presented as a first step toward the evaluation of such control devices. Flight test measurements of the pressure distributions of a ZS2G-1 model were integrated to obtain force and moment parameters acting on the model and were compared to conventional airship data. An analysis of the results using geometric devices and air ejection for inducing nonsymmetric pressure distributions are presented.
