Paper Abstract

The plume-smoke is one of the main infrared characteristic signal sources of the engine. In this paper, the infrared signal characteristic of a small test engine’s plume-smoke is studied. We conduct a quantitative observation of some specific points in the movement path of the plume-smoke by the MW and LW infrared thermal imager. Through the analysis of the smokeless and smoke infrared sequential images, we can get the infrared radiation and the transmission characteristics of the plume-smoke and their variation law with time. Experiments show that there exists a critical temperature of the plume-smoke; the radiation of background can increase when the temperature of the plume-smoke is higher than the critical temperature. On the contrary, the radiation of background decreases when the temperature of the plume-smoke is lower than the critical temperature. In this paper, the research provides a reference for further study on the infrared characteristic of the plume-smoke.
