Abstract

This paper presents the CFD simulation of a novel airship con-cept that can change the external volume and shape as a func-tion of altitude. This novel concept of airship defined in the MAAT project (the project of a stratospheric cruiser/feeder airship) is necessary for two fundamental reasons: minimizing risks due to the use of hydrogen as buoyant gas and reducing the power necessity for propulsion. The unconventional feeder system has been analyzed from ground level up to 16,000 m, which the desired operative altitude of the cruiser.
