ABSTRACT:
A rotor sideplate for inhibiting the leakage of fluid mediums across a blade and disk assembly of a gas turbine engine is disclosed. Techniques for preventing the leakage of working medium gases across the assembly beneath the platforms and for preventing the leakage of turbine cooling air are developed. Various construction details which enhance the fatigue performance of the sideplate are developed. The sideplate is supported from the rotor disk at more than one support point.
