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.

该合作研究项目的目的是研究发动机测试单元动能回收 (KER) 系统的空气动力学和声学性能。发动机测试单元的主要作用是创造必要的环境，以便在多种飞行条件下对燃气涡轮发动机进行全面的性能测试。在整个发动机测试活动中，对许多性能参数进行监测，其中发动机推力是必须以高精度测量的主要参数。发动机测试活动需要大量的测试时间和喷气燃料，以证明最终设计符合原始设计规范。目前的发动机测试单元没有办法在测试期间恢复损失能量，因此对所提出的动能回收系统的研究有可能恢复部分损失能量。
