SBIR-STTR Award

A phase I program will be directed toward the development of a highspeed, power generating turbine driven by a compressed fluid. Concepts and details will be formulated, designed, and analyzed with regards to efficiency, light weight, cost effectiveness, operating characteristics, and reliability. Overall size will be 2 inches diameter or less. Rotor/nozzle configurations will be analyzed and evaluated in conjunction with operating parameters (3 hp developed, 250 krpm, and minimum efficiency of 40%), fluids, pressures, and temperatures up to 2500 f. Bearings and seals will be evaluated and selections made. Various materials will be reviewed and selected based upon operating stresses, fluid compatibility, and temperature limits commensurate with light weight, reasonable cost, availability, and manufacturing ease. Dynamaic stability with regards to shaft, rotor, and supports will be analyzed as well as damping, bearing preload, and lubrication techniques. Computer programs will be used to predict turbine performance, dynamic balance, and stress analyses to assist in establishing the turbine's configuration. Interface requirements including mounting and shaft coupling methods will be investigated and selected in light of potential user requirements and to insure versatility and compatibility. A turbine wheel (rotor) will also be fabricated.
