Jet Mixings of Alternating-Lobe Nozzles under Pumping Air Intake and Stamping Air Intake Conditions by Zhiqiang Sheng, Yu Dan, Lan Zhang, Bowen Zhong

“…It was confirmed that the stamping air intake can be introduced to increase the cool air involved in the mixing for an infrared suppressor of a helicopter. It was found that the stamping air intake increases the amount of cool stream near the mixing tube, which can effectively decrease the temperature of the mixing tube, thus improving the infrared suppression performance. …”
