Abstract:
An airfoil assembly includes a support carrier and an airfoil unit that includes a platform, an airfoil, and a mount. The platform defines a boundary of a gas path of the airfoil assembly. The airfoil extends away from platform and the mount extends away from the platform opposite the airfoil. The support carrier is coupled with the airfoil unit and engages the mount.
