General

This paper describes a recommended practice and procedure for the correlation of test cells that are used for the performance testing of turboprop and turboshaft engines. This Aerospace Recommended Practice (ARP) shall apply to both dynamometer and propeller based testing. 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. 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.

Beneficiaries

This ARP will benefit the original equipment manufacturer (OEM), commercial users, repair stations, military depots as well as intermediate level maintenance activities. Specific cases in which the information contained herein will be beneficial are:

a. As an aid for providing correlation of test cell data between engine and airframe companies supporting commercial and military requirements.

b. As an aid for providing military maintenance facilities and commercial repair stations a method by which to correlate test cells.

c. As an aid in establishing correlation practices for new test cells, for updating, and for maintaining existing test cells.

d. As an aid to an engine manufacturer's facility in correlation of test cells used for engine development and acceptance in accordance with the applicable engine model specification.

Limitations

Known methods of turboprop/turboshaft test cell correlation include, but are not limited to, the following:

a. Back-to-Back

b. Cross-Cell

c. Correlation Engine

The "Correlation Engine" procedure is the recommended and most common method for the correlation of an engine test cell. This paper is limited to the discussion of this one method.
