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.
