<p>A turbomachinery vane or blade with a cooled platform including a coolant cavity in said platform into which a plurality of cooling fluid impingement jets are projected to impinge against the platform wall and then flow along the platform wall after impingement for cooling thereof and eventual discharge from the cooling cavity along the platform surface. A plurality of dam members extend into the cooling cavity adjacent the impingement jets so as to isolate the impingement jets from cross-flow and channel flow effects from the cooling fluid passing through the cooling cavity following impingement. CROSS-REFERENCE TO RELATED APPLICATION Some of the subject matter disclosed and claimed in this application is included in Canadian patent application Serial No. 257,995, filed July 28, 1976 entitled "Turbomachinery Vane or Blade With Cooled Platforms" in the name of Hans R.
