Corner cooled turbine nozzle

A turbine nozzle includes a hollow vane (22) joined to opposite inner and outer bands (24,26). The inner band (24) includes a forward lip (38) under the leading edge (32) of the vane (22), an aft lip (40) under the trailing edge (34) of the vane (22), and a mounting flange (42) spaced therebetween....

Zusammenfassung:	A turbine nozzle includes a hollow vane (22) joined to opposite inner and outer bands (24,26). The inner band (24) includes a forward lip (38) under the leading edge (32) of the vane (22), an aft lip (40) under the trailing edge (34) of the vane (22), and a mounting flange (42) spaced therebetween. An impingement bore (52) extends obliquely and aft from the base of the mounting flange (42) under a corner of the inner band (24) toward the aft lip (40) for impingement cooling thereof.
