Patent attributes
An aircraft has a flying wing and two wingtip hulls installed on the wingtips of the flying wing. Both of the wingtip hulls contain lighter-than-air gas to generate static lift. These wingtip hulls not only contribute to lift-generating but also help the aircraft achieve roll stability and control. Forward propulsion systems are installed at the upper-front positions of the flying wing. When vertical and/or short take-off and landing (V/STOL) capability is required, one or more lift-fan propulsion systems can be installed on the flying wing. The lift-fan propulsion systems can either be driven by their own engines or by the power transmitted from the forward propulsion systems. Payload can be carried inside the flying wing or be hung under or held above the flying wing.
