CONTEST for Lazair BUFFS -

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 c. towing the trailing aircraft in a flying direction, such that the trailing aircraft ascends to a lower altitude, wherein a difference between a speed of a high altitude wind in the flying direction at the higher altitude and a speed in the flying direction of a wind at the lower altitude equals or exceeds a takeoff velocity of the trailing aircraft plus a speed of wind across the leading aircraft sufficient to generate a force of lift on the leading aircraft which allows the leading aircraft to remain aloft.
