ARP6028 - CONFIGURATION CONTROL FOR MAINTAINING CORRELATION OF GAS TURBINE ENGINE TEST CELLS

Details
Document Number: ARP6028
Revision Number:
Title
CONFIGURATION CONTROL FOR MAINTAINING CORRELATION OF GAS TURBINE ENGINE TEST CELLS
Scope
The configuration of a test facility that exists at the time when a correlation is being carried out should be "base lined" as a condition of correlation approval acceptance, and, be maintained during the time period that the respective correlation approval lasts. This defines test facility configuration control. This is due to the fact that a change in configuration may have the potential to change the established correlation factors and measured engine performance. If such a change occurs then this should be judged by the respective OEM's or designated correlation approval authorities Subject Matter Expert (SME). In some cases, this may involve consultation with the engine project customer or airworthiness authorities. The purpose of this paper is to recommend a means of identifying, recording, documenting and maintaining the configuration status of all correlations, including those where re-approval is achieved by using statistical trending methods rather than physical back-to-back type testing. This paper can be considered applicable to all types and standards of test facilies in the aero, marine and industrial gas turbine engine businesses.
