Patent abstract
A turbine stage includes a row of airfoils and their platforms spaced laterally apart to define flow passages therebetween. Each airfoil is integrally joined to its platform at a funnel-shaped fillet along the pressure side of the airfoil which decreases in size from the leading edge towards the trailing edge. A field of film cooling holes extends through the platform along the fillet for discharging film cooling air.
