Abstract
An airship able to travel from ground to 15 km altitude is being developed on course of the European Research Project MAAT—Multibody Advanced Airship for Transportation. The airship has a cylindrical shape when completely inflated at the pressure altitude. Based on an initial research for the airship shape and aerodynamic features at given altitudes, propulsion needs were analyzed by means of numerical simulations for different flow conditions and propulsion concepts. The propulsion system is comprised of two rows of air-jets, at top and bottom of the airship, that expel cold air in order to provide propulsion thrust. Herein, we will present the steady and unsteady results of the computations regarding the interaction of the air-jets with the airship. Then, a detailed analysis on the vortex shedding from the airship is presented when it in subjected to only horizontal movement, this is further enhanced by computing the near vehicle flow when it is subject to the incoming wind. We will also present details about the total required thrust power for the various working conditions. The outcome of the research highlights the main advantages of the system to attain feasible high altitude airships.
