ABSTRACT:
A winged aircraft, adapted to takeoff and land with its longitudinal axis at a very steep angle of inclination, including: balloons that have a center of buoyancy forward of the center of gravity and tend to turn the craft into the said steep angle; a controllable-thrust stern-elevating propeller in an upright wind tunnel, having a lift rearward of the center of gravity that in horizontal flight balances the torque of the balloons; and an elongated, stiffly resilient body frame of a multiplicity of inflated small tubes extending in the fore-and-aft direction, supported by longitudinally spaced, rounded ribs, disks or the like. This frame is round in the middle and somewhat streamlined at each end, its stern portion rearwardly sloping downward at its top and upward at its bottom. The assembly of tubes, preferably extending from the foremost to the rearmost parts of the frame, is flattened into substantially linear, horizontal shape at the rear portion. Landing gear, adapted to be on the ground while the vehicle's nose is well clear of the ground, conforms to the bottom upward slope of the tubes; this slope being at an angle to the horizontal which provides the desired takeoff and landing attitude with all landing wheels on the ground. The ribs or disks are preferably spirally wound convolutions of inflated tubes or concentric tubes on a central round core which may contain a door. The vehicle has ferris-wheel-like seats, swinging from upper pivots.
