Abstract
A turbine nozzle includes a hollow vane mounted between inner and outer bands. The inner band includes a mounting flange between forward and aft lips. An aft pocket is found in the inner band between the flange and aft lip. And, an impingement bore extends through the flange into the windward half of the pocket and is directed aft toward the opposite leeward half of the pocket for co-rotation with purge flow during operation.
