Gas turbine engine with circumferential array of airfoils with platform cooling

Convective cooling of gas turbine engine airfoil platforms (60) is enhanced by grooving the interface of the platforms with corresponding platform-to-platform seals (95), thereby accelerating cooling airflow over the platform surfaces (65, 70).
