Conceptual design and analysis of hybrid airships with renewable energy

An increasing focus on hybrid airships and the developments in renewable energies has allowed a methodology for conceptual design and analysis to be described. After a model presented and its aerodynamic characteristics obtained through a computational fluid dynamics method, two types of hybrid airships, solar powered at high altitudes and hydrogen powered for cargo, are demonstrated using a wing loading as their independent variable. Then the constraints determining the design point are presented. Parametric estimates of two types for component mass are then illustrated on distribution diagrams. And the sensitivity of wing loading and its effects on hybrid airships are discussed.
