Book Description
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 lbm/sec, a work level of equal or greater than 187 Btu/lbm, and an efficiency of 86% or greater. The rotor was also evaluated to determine it's 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.

Book Description
The objective of this program was to provide and demonstrate the technology required to economically manufacture a cooled, high-temperature, radial turbine with sufficient integrity and aerodynamic performance to meet future Army requirements for a reliable, low-cost, high performance, small gas turbine engine. The work to accomplish this objective was subdivided into three phases. (Author).

Book Description
Radial turbines offer greater stage work capacity than axial turbines. If this advantage can be coupled with a capability of accommodating high turbine inlet temperatures, radial turbines will permit appreciable simplification of small gas turbine engines for use in future Army vehicles. A two-phase program is being conducted involving the design and testing of a cooled, single-stage, radial inflow turbine. A bicast rotor with solid blades was spun to failure, which occurred at a speed lower than predicted. Two spindle failures prevented a successful destructive spin-test of the rotor damaged in Turbine Build One. The third and final nozzle section was chosen from the two castings submitted by the casting vendor for evaluation. An integral-cored rotor casting was not acceptable for rig test and is being evaluated for possible use as a spin-test part. Turbine Build One was hot tested for seven hours. Considerable foreign object damage was experienced by the turbine, and performance data is not believed to be representative of the turbine design. A replacement turbine rotor and nozzle were prepared and used in Turbine Build Two. Testing was aborted because of high vibrations caused by a turbine rotor-to-shroud rub during the initial stand checkout. Turbine Build Three is now in progress, using hardware salvaged from Build Two. (Author).
