摘要： A noise attenuation device for use in a jet engine test cell for testing a jet engine comprising a carbon steel pipe which is aligned axially with direction of exhaust from the jet engine. The carbon steel pipe is positioned within an augmenter within the test cell. Cold air enters the front end of the carbon-steel pipe. Adding three times the mass of cold air to that of the hot jet exhaust allows the hot jet exhaust to mix with the cold air forming an engine exhaust-cool air mixture. When the engine exhaust-cool air mixture reaches the outlet end of the carbon steel pipe, its temperature is reduced from 3800° F. to less than 1200° F., which substantially reduces noise generated by the jet exhaust. Located in proximity to the rear end of the carbon steel pipe is an annular region which is formed between perforated side plates within the carbon steel pipe and the inner wall of the augmenter. The flow is diffused as the flow area expands in the annular region. The combination of the carbon steel pipe and the annular region slow the velocity of the jet engine exhaust-cool air mixture, further reducing noise production from the jet engine.
摘要翻译：一种用于喷气发动机测试单元中用于测试喷气发动机的噪声衰减装置，包括与来自喷气发动机的排气方向轴向对齐的碳钢管。碳钢管位于测试室内的增压器内。冷空气进入碳钢管的前端。将三倍的冷空气与热喷射排气的质量相加允许热喷射排气与形成发动机排气冷却空气混合物的冷空气混合。当发动机排气冷却空气混合物到达碳钢管的出口端时，其温度从3800°F降低到小于1200°F，这大大降低了由喷气排气产生的噪音。位于碳钢管的后端附近的是形成在碳钢管内的多孔侧板和增压器的内壁之间的环形区域。当流动区域在环形区域中膨胀时，流动扩散。碳钢管和环形区域的组合减慢了喷气发动机排气冷却空气混合物的速度，进一步减少了喷气发动机的噪音产生。
