Model of the Hindenburg airship. The reflective coating is to avoid heating up of the internal gasses.

Calculating Lifting Capacity of Airships

How big does an airship need to be to lift a particular weight or alternatively how much can an airship of a particular size lift?

Further I would like to explore how usage of different materials for the envelope affects how much can be lifted as well as how different gasses inside the envelope and outside affecting the lifting power.
