Experiment of IR suppression for nozzle with low infrared emissivity coating

摘要：

The coating with low infrared emissivity was employed to suppress the infrared radiation(IR) of axisymmetric convergent nozzle for a turbofan engine, while experimental research was conducted on the simulation test bench of turbofan engine. The infrared radiation intensity in 3-5μm of axisymmtric convergent nozzle on the orientation of 0,5,10,15,20,30,45,60,75 and 90° on horizontal plane was measured when the nozzle was obliterated low infrared emissivity coating or not. The results show that low infrared emissivity coating can reduce the IR intensity of the nozzle about 25％.The coating can distinctly suppress IR intensity of wall from nozzle but it has little effect on IR intensity of gas plum.
