Abstract
A turbine engine includes adjacent compressor and turbine sections and an interstage seal assembly interposing therebetween in cooperation with a rotor assembly of the engine to inhibit leakage of pressurized air between the sections. The interstage seal assembly includes an annular wall portions at its outer perimeter cooperating with a housing of the engine and at its inner perimeter sealingly cooperating with the rotor assembly. The wall portions of the interstage seal includes nested conical sections of opposite axial dispositions which cooperatively resist both thermal and pressure differential induced distortion of the seal assembly.
