Compressor Rotor for Gas Turbine Engine With Deep Blade Groove

摘要

A compressor rotor has a rotor centered on an axis, and a groove with opposed side edges. The groove receives a plurality of removable compressor blades, and has tangential sides. The tangential side surfaces are in contact with said tangential sides of the groove, and at least one slot is cut into the side edges. A first radial distance is measured from a radially outer edge of the side edge to a radially outer beginning point of the tangential sides of the groove. A second radial distance is radially between the radially outer beginning point of the tangential sides to a radially inner end of the tangential sides of the groove. A ratio of the first and second radial distance is between 1.1 and 5.0.

1. A compressor rotor comprising:
a rotor centered on an axis, and having a groove with opposed side edges, and said groove receiving a plurality of removable compressor blades, said groove having tangential sides, and said blades having tangential side surfaces to be in contact with said tangential sides of said groove, and at least one slot cut into said side edges; and a first radial distance defined measured from a radially outer edge of said side edge to a radially outer beginning point of said tangential sides of said groove, and a second radial distance defined radially between said radially outer beginning point of said tangential sides to a radially inner end of said tangential sides of said groove, and a ratio of said first radial distance to said second radial distance being between 1.1 and 5.0.
