ABSTRACT:
Compressor disk (10) has a plurality of rim portions (16, 20, 24) of increasing diameter. Parallel blade retention grooves (30, 32, 34) at locations commensurate with their respective rim portion diameters receive blade tongues (46, 48, 50). Dead load is decreased resulting in a smaller, lighter weight compressor.
