ABSTRACT:
An aircraft includes a nonrigid dynamically inflated airfoil wing which carries an operator. The operator is suspended by a plurality of shrouds which interconnect the wing to a control stick. The control stick position is varied to change the angle of attack of the wing. A transverse control bar is connected to the wing tips for direction control. The center of gravity of the total aircraft is rearward of the center of lift. The wing includes air intake orifices at its leading edge and at least one trailing edge exhaust aperture for inflation by airspeed relative to the wing. A spanwise tubular plenum may be employed for air flow control through the wing.
