Suspension flight control method and apparatus

Suspension flight control method and apparatus Merle T. Sandage
A flight control apparatus for use in an aircraft includes
support structure for suspending a pilot beneath a pair of wings while permitting movement of the pilot relative to the aircraft in the forward, rearward and both lateral directions. A control system is connected between the support structure and the wings for altering the geometries of the wings during flight to vary the drag and lift characteristics of the wings and alter the direction of flight and the speed/performance range of the aircraft in response to movement of the pilot relative to the aircraft in any of the forward, rearward, and lateral directions. The geometries of the wings are altered during flight by moving the leading edges between extended and retracted positions relative to the central longitudinal axis of the aircraft in response to movement of the pilot in the forward, rearward and both lateral directions relative to the aircraft.

|Hang Glider Weekly
was publisher of some key facts on the innovative company
with founder, designer, inventor
Bob Trampenau. We have strong reason to look to roots of VG
--variable geometry-- in Seedwings. The company's Sensor's fiberglass curved wing
tips and the enclosed cross bar were invented by Trampenau and
first flown in 1976 and shown in Hang Glider Weekly. He
further invented wire braced washout struts in 1978 now used on all
topless hang gliders and the wrap-around Mylar leading edge pocket in
1979 all before the UP Comet. Trampenau continued inventing; and
he first HGMA certified the curved wing tip, enclosed cross bar,
and an all-wire trailing edge reflex bridle stability system and
wire-braced washout struts and wire-reflex bridles are the two most
important stability safety features on today's hang gliders. Another
safety-and performance-feature that is significant are the flaps on a hang
glider. Seedwings owner Bob Trampenau invented the current flap system in
1992, and as yet no one has copied it. The Seedwings
trademark is internationally operated out of the headquarters in California.

The deployable wing of the present invention comprises an internal structure having diverging leading edge spars attached to a keel spar and cross spars to form a delta wing configuration. This internal structure is enclosed within a volume defined by a fabric sail having an upper section and a lower section. This fabric sail volume is internally pressurized through a ram air intake at the nose stagnation point. This deployable wing can be folded closed, extracted from an aircraft, deployed in the air and landed with the aid of parachutes.

inflation systems for all types of wings, in order to obtain the lightest
and least cumbersome flying machine possible.
