Abstract:

This report presents the component test results and analysis for Phases 3, 4 and 5 of the 5-lbsec axial-centrifugal compressor. Separate component tests were carried out to evaluate the two-stage axial compressor, the centrifugal compressor, and the combined axial-centrifugal compressor. Additional static blow tests were also conducted on the axial and centrifugal stage inlet guide vanes to determine their performance characteristics. The assembly procedure, buildup clearances, and test procedure are described herein, as well as the instrumentation, data reduction procedure, and test facilities. The test results are presented for all component tests carried out in this program as well as for tests from a related centrifugal compressor development program. The analysis of the test results are reported herein as well as recommendations for future development programs. This program demonstrated the feasibility of designing a 5-lbsec, two-stage axial-centrifugal compressor in the 151 pressure ratio class and provided insight into the matching of axial-centrifugal compressors.
