    Abstract

    In this paper, we have an aim developing the next-generation-type airship for resolving airworthiness problems especially for mooring condition. For this purpose, we propose the TORUS-TYPE AIRSHIP. The torus-type airship will have the advanced characteristics of airworthiness especially at mooring condition, and have advanced maneuverability especially for movement of any direction( forward, backward, left, right, rotation), but some instability at flight condition are considered. At first, we designed a simplified torus-type airship model, and carried out towing experiments about aerodynamic characteristics of the model in upper water space of our huge towing tank instead of carrying out experiments in a wind tunnel. By introducing torus-type airship, we will be able to minimize the mooring area, reduce the maximum mooring forces, and in the result prevent the body damage at mooring. In the second, we developed a 3D Flightsimulation program using the data from the experiment. By using the numerical simulation, we can evaluate the performance of the torustype airship from various viewpoint including mooring. © 2010 by the International Council of Aeronautical Sciences - ICAS.
