Product Name: Variable Geometry Wing
Product Description
This idea provides a new solution to the classic dilemma of aircraft
design--big wings won't go fast and little ones won't go slow. Current
solutions provide moveable wing systems that alter wing shape, not area. This
invention goes a step further. Two fabric airfoils are rolled on a drum and
driven in and out on tracks that run from fuselage to wingtip. This tensile skin
is designed to maximize lift at low speeds. A low drag fixed wing is designed
for high speeds, minimizing power requirements at cruise. At take off, the
skin is fully deployed to maximize lift, and at cruise it is fully retracted,
leaving the fixed wing clean and drag free.
The invention finds greatest utility at noise sensitive, real estate limited
inner-city airports. The increased lift of the airfoil will allow lower take-off
and climb speeds, reducing runway requirements, and will facilitate steeper
climbs and descents. Altitude to distance downrange could be increased by 50%
and the aircraft may use 40% less runway.
Weight and balance concerns are routine design challenges. State of the art
sail design addresses the airfoil shaping of tensile skins. Kevlar, carbon
fiber, and other very high strength-to-weight materials are available. The
drives and hardware are common. And finally, the fixed wing is simpler to build
than current designs, and in conjunction with dynamic airfoils, lighter for a
given area.
