Abstract:

A test was conducted by the Air Force Aero Propulsion Laboratory to study the performance of jet engine compressors during engine speed transients. Effective analysis of the test results required accurate, high speed data acquisition during the transients. On-line reduction and display of the performance data was desirable to improve the efficiency of the test operations. This paper describes the software that was designed and implemented to acquire and display the performance data. The software controls data acquisition and calibration equipment, provides on-line calibration of transducers, records the data, reduces and displays performance data including graphics, and allows the test operator to control these functions.
