ROTOR FOR A GAS TURBINE ENGINE

摘要

A rotor for a gas turbine engine includes a central wheel and a plurality of blades that extend outwardly from the central wheel. The blades are non-uniform to reduce flutter and forced response effects induced during operation of a gas turbine engine including the rotor.

主权项

1. A rotor for use in a gas turbine engine, the rotor comprising
a central wheel arranged around a central axis, a plurality of first frequency blades that extend outward from the central wheel in a radial direction away from the central axis, each of the first frequency blades formed to include at least one first-frequency-modification slot that extends inward in the radial direction from a radially-outward tip of the first frequency blade toward the central wheel, and a plurality of second frequency blades that extend outward from the central wheel in the radial direction away from the central axis, each of the second frequency blades arranged circumferentially between two first frequency blades and formed to include at least one second-frequency-modification slot, different from the at least one first-frequency-modification slot, that extends inward in the radial direction from a radially-outward tip of the second frequency blade toward the central wheel.
