Abstract

A turbine blade assembly (100) is disclosed. In one embodiment, the turbine blade assembly (100) may generally include a turbine blade (102) having a root portion (104) and an airfoil (106). The airfoil (106) may extend radially from the root portion (104) to an airfoil tip (114). Additionally, the turbine blade assembly (100) may include a composite rod (122) extending within the turbine blade (102). The composite rod (122) may include a first end (130) coupled to the airfoil at the airfoil (106) tip and a second end (132) coupled to the root portion (104). Moreover, the coefficient of thermal expansion of the composite rod (122) may be designed to be less than or equal to the coefficient of thermal expansion of the airfoil (106).
