IMPROVED INLET PASSAGEWAY AND SEALING IN A TURBINE WIND POWER GENERATING SYSTEM wherein sharp very small radii of curvature end portions at the mouth or inlet to the passageway avoid turbulence thus enhancing inlet airflow. Transitional portions of the passageway are arranged at angles of inclination with the horizontal to provide for smooth airflow to a rear impact and transfer portion of the passageway which takes a concave parti-circular configuration. Turbulence adjacent the end portions and within the inlet passageway is thus avoided. Sealing means between an annular shroud or blade tip ring and an adjacent stationary ring take the form of labyrinth seals minimizing loss of airflow through the blades.
