Abstract

PURPOSE: To enhance locational load performance without degrading the rating performance by providing the blade with a slit gutter which opens to the blade's leading edge, and arranging a throttle hole which is in communication with this slit gutter.
CONSTITUTION: Fluid will stay in the slit gutter 3 practically speaking as well as a stream with the same or reverse direction as the main stream is produced in the slit gutter 3, so that the streamline of the fluid at the leading edge part 2 becomes smoother and also the locational load performance can be improved. The fluid at the surface of the blade can be prevented from separation by blowout or suction of the fluid through the throttle hole while energy loss due to collision can be reduced thanks to the sharpness in the form of the leading edge 2 itself.
