NASA Glenn与美国工业界合作，完成了一项关于分离流喷嘴排气系统减少喷气噪音的详尽实验研究。该研究开发了一个数据库，不同的涵道比喷嘴，筛选最安静的配置，并获得相关的数据，预测羽流的行为，并最终其相应的喷流噪声。几种排气系统配置在起飞功率下提供了超过2.5 EPNdB的喷气噪声降低。这些数据在NASA GRC主办的一次会议上传播给美国航空航天工业，会议记录见本报告。
NASA Glenn, in partnership with US industry, completed an exhaustive experimental study on jet noise reduction from separate flow nozzle exhaust systems. The study developed a data base on various bypass ratio nozzles, screened quietest configurations and acquired pertinent data for predicting the plume behavior and ultimately its corresponding jet noise. Several exhaust system configurations provided over 2.5 EPNdB jet noise reduction at take-off power. These data were disseminated to US aerospace industry in a conference hosted by NASA GRC whose proceedings are shown in this report.
