The present invention relates generally to the field of lighter-than-air ships and more particularly to a airship that uses hydrogen as a lift gas.

Before lifting off on your scientific inquiry into ballooning and lighter-than-air flight, it helps to have some background information about the history of ballooning.

Balloons and airships are lighter-than-air , and fly because they are buoyant, which is to say that the total weight of the aircraft is less than the weight of the air it displaces.

Helium (an inert non-flammable lighter-than-air gas) sustains the Air Rotor which ascends to an altitude for best winds.
