Like all lighter-than-air vehicles, the payload capability of the SkyCat increases exponentially with size. Unlike airships, however, its aerodynamically-derived lift enables the SkyCat to gain significantly further from the benefits of scale.
Light/heavy range: while conventional airships are limited to operating in a narrow band between approx. 5% light and 8% heavy, the SkyCat can operate between 8% light and 40% heavy, thereby greatly increasing its payload capability while eliminating the need for taking on ballast on discharging its load.
Landing and takeoff distances: in STOL mode, the SkyCat can land and take off in five hull lengths, while in VTOL mode, by virtue of vectored thrust engines, the vehicles are literally able to set down and lift off in their own length.
Hull pressure: the hull is a pressure-stabilised, non-rigid structure, operating at 1%-2% pressure above ambient, with the shape maintained by ballonets (air bags) which automatically deflate and inflate to compensate for changes in outside pressure.
Material construction: the envelope is constructed of heat-bonded, high-tensile laminated fabric, incorporating a Mylar film that provides the gas barrier. The lift gas is helium and totally inert. The payload module is formed from Kevlar composite material of exceptional strength and can be configured for whatever interior design fit is required.
