Title:
TURBINE FOR WAVE ACTIVATED POWER GENERATION WITH SELF-ADJUSTABLE PITCH BLADE
Document Type and Number:
Japanese Patent JPS63219801
Kind Code:
A
Abstract:
PURPOSE:To enhance starting characteristics by rotatably holding a turbine blade on a rotor hub on the entering edge side than at the moment center. CONSTITUTION:A holding rod 22 and a stopper pin 24 are provided on the flat surface of a mounting base portion 20 of a turbine blade 16. A recessed portion 28 to store the mounting base portion 20 of the turbine blade 16 is provided on the outer circumferential surface of a rotor hub 14. In the bottom portion of the recessed portion 28, a hole 30 which passes through the circumferential wall of the rotor hub 14 corresponding to the holding rod 22 and a groove 32 which stores the stopper pin 24 and conforms with the locus which is drawn by the pin 24 with the rotation of the turbine blade 16 are formed. The holding rod 22 is provided on the entering edge side than at the moment center of the turbine blade. With this arrangement, the self-starting characteristics of the turbine blade after the stalling can be improved.
