Novel rotary spool compressor design and preliminary prototype performance.

Author(s) : KEMP G., GARRETT N., GROLL E. A.

Summary

The "rotary spool compressor", a positive displacement rotary machine, is introduced. The compressor design fundamentals are described. A single stage prototype was designed and manufactured. A test stand was constructed to confirm the rotary spool compressor's mechanical operation and to determine if adequate sealing could be achieved. The prototype operated successfully achieving pressure ratios greater than 35:1 with air as the working fluid. Preliminary test results are presented including: attainable dead-head pressure ratio, volumetric efficiency and isentropic efficiency. The experimental performance was found to compare favourably with current positive displacement compressors. Early evaluation suggests that the rotary spool compressor may offer performance improvements and reduced costs relative to current positive displacement compressor technologies.
