APU Gas Turbine Engine Test Cell Correlation
ARP5435A
This paper describes a recommended practice and procedure for the correlation of test cells that are used for the performance testing of APU (auxiliary power unit) engines. Test cell correlation is performed to determine the effect of any given test cell enclosure and equipment on the performance of an engine relative to the baseline performance of that engine. The baseline performance is generally determined at the original equipment manufacturer (OEM) designated test facility. Although no original equipment manufacturer (OEM) documents are actually referenced, the experience and knowledge of several OEMs contributed to the development of this document. Each engine Manufacturer has their own practices relating to correlation and they will be used by those OEMs for the purpose of establishing certified test facilities.
Rationale:
ARP5435A was updated per the Five-Year Review requirement.
The SAE EG-1E committee is composed of a cross section of representatives from OEMs, commercial users, repair stations, and military depots. Based on the inputs from representatives of these various areas of interest, it was concluded that there was a need for a standardized procedure for correlating an APU gas turbine test cell. This paper represents the committee's best effort to satisfy the interest of all parties concerned and arrive at a valid realistic correlation procedure. It is the belief of the committee members that this document meets that objective.
ARP5435A has been reaffirmed to comply with the SAE Five-Year Review policy.
