Abstract:
A wind turbine for generating power comprising:(a) one or more blades mounted to a shaft for rotational movement in response to an airflow;(b) a housing having a generally central longitudinal axis, the housing surrounding the one or more blades and the shaft, wherein the housing includes an inlet opening and an outlet opening;(c) an adjustable scoop operably associated with the housing to alter the airflow entering the inlet opening, wherein the adjustable scoop comprises a plurality of flanges, and wherein a first end of each flange is movably connected to a generally circular band and each flange extends longitudinally from the generally circular band to an outer end, wherein the plurality of flanges consists of inner flanges and outer flanges; and(d) an actuating device to rotate each flange relative to the generally circular band, such that the radial position of the outer end of each flange is adjustable, wherein the inner flanges may be adjusted to form a cone with a smaller inlet diameter than that of the generally circular band, and wherein the inner flanges and outer flanges may be adjusted to mate and form a scoop with a larger inlet diameter than that of the generally circular band.
