Abstract
Official abstract text for this publication.
A hydraulic blade speed control apparatus and method. The apparatus includes a rotor assembly comprising a shaft; a first blade assembly pivotably attached to the shaft at a first initial position; a second blade assembly pivotably attached to the shaft assembly at a second initial position opposite to the first initial position; and a hydraulic movement mechanism. An initial angle of 180 degrees exists between the first blade assembly with said respect to the second blade assembly. The rotor assembly is configured to rotate the first blade assembly and the second blade assembly in a first direction and a second direction opposite to the first direction. The hydraulic movement mechanism is configured to pivotably move the first blade assembly in different angular positions with respect to the rotor assembly and the second blade assembly.
First claim
Opening claim text (preview).
