The thermodynamic balance of a next-generation hybrid solar thermal airship 2019-01-1868

This paper focuses on the thermodynamic design of a hot air airship with a hybrid heating system which is based on a coupled system by solar and electric heating. It has been specifically designed for vigilance and reconnaissance operations and emergency. The system has been developed starting from earlier solar balloons experience which has been conducted in both Europe and the USA and has the objective of the minimum deployment time. A complete energy balance is produced by considering an electric propulsion system which benefits of the residual heat produced by fuel cells. Values have been verified for a tangency of 500 m with the maximum payload of 200 kg. Different combinations of tangency and payload have been considered. .
