>>1287936There are significant benefits to going large when building airships. The ability to lift cargo will increase rapidly as you increase the dimensions of the airship.
it ought to be safe to assume that we can grow the thickness proportional. By that I mean that if I double the dimensions of the airship, then I also double the thickness of the envelope. So an airship 30 m long, 10 m tall, should have an envelope with twice the thickness of an airship 15 m long, 5 m tall.
