Abstract

A possible propulsion system concept for a stratospheric multi-body airship has been investigated. It features distributed propulsion to fulfill thrust and stabilization demands of the airship. In the frame of this research a simulation model for the propulsion system has been developed in Matlab/Simulink. The propulsion system’s main components are propellers, which are driven by electro motors, back-up batteries and gas turbine power plants to supply the necessary electric energy. All components have been adapted to work in ambient conditions at an altitude of 20km. The investigations have demonstrated adequate system dynamics and confirmed the sizing of power plants and back-up batteries. The control system has shown adequate stability and, therefore, guarantees the provision of the demanded thrusts and powers.
