Abstract This paper contains the results of calculation study of options for a system for heating airship hull in order to select the most energy-efficient solutions that should fit into the existing structure. In building computation models, real geometrical dimensions of the airship hull were used with the maximum diameter of 20.8 m and length of 104 m. Non-stationary three-dimensional turbulent flow was calculated using the Flow Vision 2.5 software package. Computer modeling of blowing airship hull with wind made it possible to determine the empirical formula for heat transfer coefficient with accuracy of 15% for preliminary calculations of the heat flux. Numerical modeling of snow fall onto the airship hull showed that the maximum concentration of snow is observed in the upper part of the hull in the sector about 60 degrees. On the basis of numerical experiments it was shown that feeding hot air into the bottom compartment or from below into the gap between the shells is inefficient from the standpoint of the upper surface of the airship reaching
