内容記述 | This paper describes the noise test of a notched nozzle using a demonstrator engine in outdoor environment. The notch, a tiny dent formed at the nozzle lip, is expected to suppress both jet mixing noise and thrust loss due to the mixing enhancement. Authors have continued research and development on this mixing device through experimental and computational approaches. As a result, a revised version of the notched nozzle, 18-notch, was proposed and tested in the model tests under cold and hot conditions. An experimental validation with the larger-scale 18-notched nozzle was then conducted using a turbo-jet engine. This paper outlines the noise test setup with this engine and the test results. The newly proposed notched nozzle showed the improvement in noise radiation characteristics and provided a potential reduction in effective perceived noise level as much as 1 dB compared to the baseline conical nozzle. | |||||
