摘要： A modular turbine blade assembly (10) usable in a gas turbine engine (12) and formed from an airfoil (28) and an independent, modular platform (16) supported by one or more clevis arm supports (14) extending radially inward from the modular platform (16) to a disk is disclosed. The clevis arm support may support the modular platform while a separate dovetail attachment supports the generally hollow airfoil. The clevis arm support (14) may be formed from at least two arms (20, 22) designed to reduce stress from a pin receiving orifice (24) at a distal end (26) of the two arms (20, 22) to the platform (16). The independent arms (20, 22) minimize stress concentrations caused by centrifugal loading in the support. The arms (20, 22) may be modified independently of each other, such as thickness and support angle. The clevis arm support (14) enables use of a modular platform system for the modular turbine blade (10).
