Abstract:

The objective of this program was the design and fabrication of a air-cooled high-temperature radial turbine HTRT intended for experimental evaluation in a warm turbine test facility at the Lewis Research Center. The rotor and vane were designed to be tested as a scaled version rotor diameter of 14.4 inches diameter of a 8.021 inch diameter rotor designed to be capable of operating with a rotor inlet temperature RIT of 2300 deg. F, a nominal mass flow of 4.56 lbmsec, a work level of equal or greater than 187 Btulbm, and an efficiency of 86 or greater. The rotor was also evaluated to determine its feasibility to operate at 2500 deg F RIT. The rotor design conformed to the rotor blade flow path specified by NASA for compatibility with their test equipment. Fabrication was accomplished on three rotors, a bladeless rotor, a solid rotor, and an air-cooled rotor.
