Experimental investigation of air-cooled turbine blades in turbojet engine VII :rotor-blade fabrication procedures

Long, Roger A., Esgar, Jack B.

Fabrication procedures for a variety of air-cooled turbine-blade configuration, which were used in experimental investigations to determine the effectiveness of air-cooled blades in a turbojet engine are presented. The blade shells were cast or formed from sheet metal or tubes. Additional heat-transfer surface was provided in the coolant passage by brazing fins or small tubes to the blade shell. Fabrication of blades with special methods of cooling leading and trailing edges is also discussed.
