THE ELEVATED STABILIZED PLATFORM.
Abstract
During recent years the importance of the tethered elevated stabilized platform has been demonstrated by its emergence in several forms in different countries throughout the world. Its chief application has been for enhancement of over-the-horizon surveillance. This report describes a unique Elevated Stabilized Platform (ESP) concept which has few, if any, of the disadvantages of its helicopter predecessor. It has no main gearbox, no rotor blade articulation, and no separate control system, as such. As a matter of fact, in its simplest form it does not have any moving parts, except for a set of bearings and, of course, the lifting rotors themselves. Although it can maintain a 300 pound payload at 2500 feet altitude, this ESP would not have any subcomponents weighing more than 10 pounds and when in the stowed configuration, its total volume would be of the order of 15 cubic feet.
