摘要
依据已建立的亚燃冲压发动机一体化模型,采用可拓学理论中物元与关联函数的概念,将亚燃冲压发动机传感器选型中各个因素间的关系转化成关联函数矩阵,运用层次分析法确定各个因素的权重值,提出一种应用于亚燃冲压发动机传感器选型的综合评价方法。通过对亚燃冲压发动机燃烧室进口温度传感器选型的验证,表明此方法与工程实践相结合,可行性较高。
The ramjet has many controllable and measurable parameters.Thus,the selection and optimization of sensors are especially important.According to the established ramjet engine integrated model,the concept of object and associated function in the extension theory was used,which changed the relation of various factors in sensor selection to the associated function matrix.Then the analytic hierarchy process was applied to determine the weight values of different factors.Eventually,a comprehensive evaluation method used in ramjet of sensor selection was proposed.The method is proved to be feasible and well combined with practical project by using it in the sensor selection of subsonic combustion ramjet combustor inlet.
