METHOD AND APPARATUS FOR REDUCING ROTOR ASSEMBLY CIRCUMFERENTIAL RIM STRESS
A rotor assembly (10) for a gas turbine engine (12) operates with reduced circumferential rim stress. The rotor assembly includes a rotor (14) including a plurality of rotor blades (26) extending radially outward from an annular rim (20). A root fillet (80) extends circumferentially around each blad...

| description | A rotor assembly (10) for a gas turbine engine (12) operates with reduced circumferential rim stress. The rotor assembly includes a rotor (14) including a plurality of rotor blades (26) extending radially outward from an annular rim (20). A root fillet (80) extends circumferentially around each blade between the blades and rim. The rim includes an outer surface (28) including a plurality of concave indentations (90) extending between adjacent rotor blades and forming a compound radius. Each indentation extends from a leading edge (40) of the rotor blades towards a trailing edge (42) of the rotor blades. |
