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...
1. An air vehicle comprising:(a) one and only one main wing means for both generating aerodynamic lift and carrying payload, and (b) said main wing means having a wing shape of a straight wing, and (c) at least one internal payload cabin means for carrying payload being constructed inside said main wing means, and (d) said main wing means having two wingtips which being the two tips of said main wing means, and (e) at least one buoyancy hull means for generating static lift by containing lighter-than-air gas being installed at each of said two wingtips, ...
