1. Single Stage Centrifugal Compressor Development Kevin Finney Ray Zhou Xiaoyi Li Krishna Murty Jinying Zhu Brian Gulliver Dipjyoti Acharya July 23, 2003 Compressor MotorCoupler

2. Curved Blade Impellers –Balancing completed and parts returned Extra Motor and Controller Ordered –Should arrive September 5 th –Extra controller in rotation Straight Blade Impeller –Being sent to American Hoffman for balancing Inlet Guide Vane –Received from 3-Dimensional Engineering Status of Compressor Parts

3. Collector –Manufactured and assembled with pipe flanges –Ready for attachment to mass flow meter

4. Compressor Testing Motor Characterization –Free Spin Power Test

5. Compressor Testing Issues Controller Problem –Occurred after free spin test –Received new controller from Koford –Ran motor since and new controller works

6. Compressor Testing Blank Shaft Testing –Bearing and coupler losses –Shaft Alignment

7. Compressor Assembly Animation

8. Future of Compressor Development Run coupler and bearing test Attach pressure and temperature transducers Run compressor with curved and straight blade impellers Compare results of both impellers
