摘要
A lighter-than-air (LTA) wind energy conversion system (WECS) wherein the LTA envelope carries a main rotor and electrical generator to take advantage of high wind speeds available at high altitudes. The LTA envelope is tethered to a ground based mooring system designed to provide self-orientation for the LTA envelope. In a preferred embodiment, heavy mechanical transmissions are eliminated by providing a radial disk diffuser coupled to a main rotor which, upon rotation, drives an induction turbine positioned within a substantially linear duct which is, in turn, preferably located along the longitudinal axis of the LTA envelope. The output of the induction turbine is coupled to an electrical generator whose output is, in turn, transmitted to the ground via the tethering system. In an alternate embodiment, the main rotor may itself be ducted.
