prize will be bragging rights that u da man !
WHO WROTE THIS and why ?
I
CLAIM:
1. A system for wind-powered flight, comprising a tethered low-speed,
high-drag leading aircraft, adapted to remain aloft under a force of lift
provided by a high altitude wind acting against the aircraft in a flying
direction, a force of drag against the leading aircraft being opposed by a
tether attached to the leading aircraft, for wind-powered ascent to a
first altitude, and a low-speed, low-drag trailing aircraft tethered to
the leading aircraft, and adapted to remain aloft under a force of lift
provided by one or more airfoils moving through air at a second altitude
which is lower than the first altitude, wherein the leading aircraft
extracts wind energy from the high altitude wind to tow the trailing
aircraft at a sufficient air speed to maintain the trailing aircraft
aloft.
2. The system of claim 1 in which the leading aircraft is a kite.
3. The system of claim 1 in which the trailing aircraft is a glider.
4. The system of claim 1 in which the leading aircraft is adapted to
transport one or more passengers or cargo.
5. The system of claim 1 in which the trailing aircraft is adapted to
transport one or more passengers or cargo.
6. A method of wind-powered flight utilizing a tethered low-speed,
high-drag leading aircraft adapted to remain aloft under a force of lift
provided by a high altitude wind acting against the aircraft in a flying
direction, a force of drag against the leading aircraft being opposed by a
tether attached to the leading aircraft, and a low-speed, low-drag
trailing aircraft tethered to the leading aircraft and adapted to remain
aloft under a force of lift provided by one or more airfoils moving
through air in the flying direction, comprising the steps of a. tethering
the leading aircraft to the trailing aircraft, b. stabilizing the leading
aircraft so that it ascends to a higher altitude, and

(54) SYSTEM AND METHOD FOR
WIND-POWERED FLIGHT
ABSTRACT: A system and method for wind-powered flight, comprising a low-speed, highdrag leading aircraft such as a kite, tethered to a low-speed, low-drag trailing aircraft, such as a glider. The leading aircraft is launched, and when the leading aircraft ascends into winds which are significantly greater than winds at the ground level and the takeoff velocity of the trailing aircraft, the leading aircraft begins to tow the trailing aircraft. The trailing aircraft becomes airborne and can be flown at a low air speed to maintain a constant drag on the leading aircraft, which in turn provides thrust to maintain the trailing aircraft aloft at the lower altitude.
