Hybrid airship with three lift-generating factors

Abstract

A hybrid airship is characterized by the fact that it uses the total lift force generated by three factors, the first factor being the shape of the airship's envelope (1) having an airfoil cross-section, which generates the lift force during forward movement, the second factor being a tank (2) or a set of tanks with a lifting gas, placed inside the airship's envelope (1) in its upper part, and the third factor being heated air, supplied from the gondola (4) to the air space (3) of the airship's envelope (1) through channels placed in its lower part, which air completely fills the remaining free space of the airship's envelope and constitutes the main component of the total lift force.
