Air Ship Design

10/06/2010 1:25 AM

For years I have been designing an air ship to match the shape and demensions of the star ship Enterprise NCC 1701 and have overcome many problems, however, in order to keep from losing so much helium through diffusion through the outer covering I would like to know if there is an element that repels helium or is less diffusable by it? Is there is top chemist out there who can offer something better than mylar? My ship design is 154 feet wide at the saucer section and about 320 in length over all. With tens of thousands of square feet of outer canvas and about a quarter million cubic feet of helium, helium loss could be my biggest problem. My weight budget allows for about one ounce per square foot of outer covering. so I can have multiple layers. Polyethelene plastic stops radiation due to the hydrogen atoms in the molecule, would this be a clue to a solution?

Your dimensions for the ship are incorrect:

USS Enterprise NCC-1701 (Constitution Class Starship)

Widest point (Saucer): 127.1 Meter

OA Length: 288.6 Meter

It still sounds pretty frickin' cool, though! Good luck.

Your biggest problem is that you probably don't have any Di-lithium Crystals to power your craft. *** As to your leakage problem, helium can't leak through metals, unless they're porous. *** So, you may be able to slow the loss without any real weight gain. *** A real weight gain is anything over 0.1g/sq. ft. *** Try using space blanket mylar film. *** It has an aluminum film evaporated onto the plastic film. *** Check it out first, there may be different grades. *** Try to find one that you can't see through, or better yet one that no light can get through.

Why the helium? It'll make everybody sound like Donald Duck.
