Abstract:
An airfoil for a gas turbine engine includes a platform having an integral heat shield extending over a seal. Various construction details are developed that disclose a heat shield that protects the seal structure from damage due to exposure to hot gases within the gas turbine engine. In a particular embodiment, a turbine vane includes a platform having a heat shield extending from the leading edge of the platform and a recess. The heat shield extends over the outward surface of a honeycomb seal that is disposed within the recess.
