Analysis of the enrichment jet plane engine's UV image histogram

Abstract

Abstract: It is a trend in the wo rld now that uses state maintain method to maintain the jet plane’s engine by taking advantage of the advanced UV sensors and UV CCD camera. Enrichment phenomenon is one of the most popular plane engine failures, and it has large damage to the plane engines. In this paper, a new technology will be introduced to determine plane engine’s enrichment phenomenon by using UV image processing method. The new technology acquires the enrichment plane engine’s UV images and then extracts the features by analyzing those UV image’s histogram and other histogram’s characteri stics just like the mean value, the maximum value, the minimum value and the sta ndard deviation of grey scale. Keywords: information optics, enrichment phenomenon, UV image, Histogram, feature extraction 1. Introduction The hour-maintain method is adopted in former Soviet Union and many developing countries to maintain jet plane’s engine. By this method, no matter what state the jet plane engine is in, it must be maintained after it has worked over the time period determined by the factory. But in the developed countries, the state-main tain method is widely used to maintain the jet plane’s engine. This method uses advanced sensors to detect the engine’s working state in real time mode, and then to decided whether the engine need to be maintained. Because there is plenty of fuel which does no t combust completely in the tail flame of the engine. This incompletely combusted fuel w ill generate high density carbon, nitrogen and hydrogen, and it will create chemical inter actions which will generate UV radiation. Among these chemical interactions, the chem iluminescence caused by CO+O takes the most important role to generate UV radiation. So UV li ght will be generated while jet plane engine is working, and using UV image signal processing met hod to determine the engine’s working state is possible.
