Abstract
The multi-lug attachment of the blades to the disk of a turbine rotor of a gas turbine engine, where the blades are air-cooled, optimizes weight reduction and tensile stress by attachment including a pair of lugs that transitions from a contoured airfoil to a pair of parallel rails releasably attached to complementary recesses formed in the disk. One lug is transitioned from the pressure surface to the attachment surface and the other lug is transitioned from the suction surface to the attachment surface. The lugs are tapered to optimize the attachment.
