The objective of this collaborative research project is to investigate the aerodynamic and acoustic performance of a kinetic energy recovery (KER) system for engine test cells. The primary role of an engine test cell is to create the necessary environment to conduct a comprehensive list of performance test for gas turbine engines for multitude of flight conditions. A number of performance parameters are monitored throughout the engine test campaign where the engine thrust is the dominant parameter that must be measured to a high degree of accuracy. The engine test campaign requires an extensive number of test hours and jet fuel to certify that the final design complies with the original design specifications. Current engine test cells do not have the means to recuperate the loss energy during the test and hence an investigation of the proposed kinetic energy recovery system has the potential to recover a portion of the loss energy.
