This paper analyses the model of volume control of an innovative stratospheric airship concept designed to use hydrogen as a buoyant gas. This paper presents a mathematical model which allows modelling the airship volume changes with altitude. CFD evaluation at different altitudes has been performed. CIRA and Standard Atmosphere models have been compared.

Abstract
This paper analyses the model of volume control of an innovative stratospheric airship concept designed to use hydrogen as a buoyant gas. This paper presents a mathematical model which allows modelling the airship volume changes with altitude. CFD evaluation at different altitudes has been performed. CIRA and Standard Atmosphere models have been compared.
