The flying submarine

"The Aeroscraft Pelican is 230 ft. long and has a volume of 600,000 cu. ft. and will be able to take off and land vertically."

Controlled by 'COSH': "Unlike other airships, the Aeroscraft is the only air vehicle designed with the patent-pending control of static heaviness system that controls the vehicle's buoyancy to be heavier-than-air during ground operations or lighter-than-air during flight, acting as a “flying submarine.” The control of static heaviness system internally ballasts the non-flammable helium into the aircraft’s helium pressure envelopes (HPEs)."

I once had the idea to use pumps to convert helium gas to a liquid into hipg pressure bottles to reduce size of the helium bags (and vice versa) to control buoyancy, but of course the pumps would have been too heavy. Seems Aerostech uses another approach, i wonder how this is supposed to work.. maybe the gas is heated, or cooled for control?

Here are some pictures from an early prototype:

Looks impressive, I couldn't find any details about the maximum cargo weight.

I wondered about that as well but this is all I could find. From the second link:

Aeroscraft next step is an airship with twice the Pelican’s dimensions (450 ft. long and 3.8 million cu. ft.), capable of carrying a 66-ton payload over a 3,000-nm range.

So I'm guessing about half those numbers with the current prototype?

The Shenandoah collected water vapor from the engine exhaust to counteract the weight loss from burning fuel. Helium was so expensive and rare then that they couldn't afford to vent it.
