GAS TURBINE ENGINE BLADE WITH VARIABLE DENSITY AND WIDE CHORD TIP

摘要

A blade (64) for a gas turbine engine includes a body that includes an airfoil (78) that extends in a radial direction from a 0% span position near an airfoil base to a 100% span position at an airfoil tip (80). The airfoil includes a first portion (92) near the airfoil base with a first density and includes a second portion (94) near the airfoil tip (80) with a second density. The second density is less than the first density. The second portion (94) includes an increasing true chord length in the radial direction.
