ABSTRACT: The traditional approach to establishing test cell correlation factors is expensive and time consuming requiring multiple engine runs to establish a parametric database for comparison. While a complete alternative to this process, is unlikely, it is clear that there are procedures and tools that can be implemented to minimize the cost and expense of the actual correlation process. The objective is to identify and evaluate these concepts for possible integration into the correlation process. To aid the process of cell correlation work will focus on the one dimensional flow model which has been in continuous development over the last 30 years for use as a design verification tool. This model will be adapted for use in determining correlation values for existing test cells. A comparison of the analytically derived thrust correction factors can then be compared to actual factors established for those cells through the traditional methods. BENEFIT: A method of reliably predicting or monitoring test cell correlation factors, i.e. test cell health, is frequently discussed with commercial test cell owners. Owners and potential owners are very interested in reducing the financial risk associated with test cell correlation and re-correlation. A link between analytical test cell correlations and overall test cell health monitoring is envisioned to develop a performance predictor for both commercial and military markets. Overall, it is believed that strong market demand can be created for a product that demonstrates ability to improve operational efficiencies of engine test cell throughout the world.
