Unlike most airship designs,  it does not have a circular cross-section, having adopted an elliptical  shape with a contoured and flattened hull.This shaping is  deliberate so that it acts as a lifting body, contributing aerodynamic  lift while the airship is in forward motion; generating up to half of  the airship's lift in a similar manner to that of a conventional  fixed-wing aeroplane.Buoyancy is also provided by helium contained  within the envelope, the pressure from which maintains the airship's  unique shape. Between 60 percent and 80 percent of the aircraft's weight  is supported by the lighter-than-air helium.[ATTACH=full]230898[/ATTACH]</blockquote>
