Title:
METHOD FOR CONFIGURING LEADING EDGE OF STATOR PLATFORM OF COMPRESSOR, AND CORRESPONDING STATOR PLATFORM
Document Type and Number:
WIPO Patent Application WO/2022/121564
Kind Code:
A1
Abstract:
The present invention relates to a method for configuring a leading edge of a stator platform of a compressor, and a corresponding stator platform. Said configuration method comprises: simplifying the flowing of an airflow at the root of a rotor blade into the flowing of a free jet, and determining an airflow expansion angle according to the Mach number of the incoming flow at the root of a stator blade; calculating a radial height difference between a first end point on a leading edge of a stator platform and a trailing edge of an adjacent rotor platform by using an axial distance between the trailing edge of the adjacent rotor platform and the leading edge of the stator platform, the airflow expansion angle and a deviation coefficient; determining, on the basis of the radial height difference, the position of the first end point on the leading edge of the stator platform; determining the intersection point of the leading edge of the stator blade and the stator platform as the position of a second end point on the leading edge of the stator platform; and determining a profile line between the first end point and the second end point by bridging spline curves, so that the tail end of the profile line is tangent to the intersection line of the root of the stator blade and the stator platform, and the starting end of the profile line is kept on the same plane as the side wall of the leading edge of the stator platform.
