对航空发动机滑油箱油量测量技术进行了研究。首先概述了滑油箱油量的测量方式及原理,并在此基础上运用UG二次开发对航空发动机滑油箱油量分析系统进行了开发。通过该系统对航空发动机的滑油箱滑油模型进行了分析,建立了传感器浸油深度、飞机姿态角与滑油体积关系的三维数据库,为后续对滑油箱油量的实时测量提供数据库。 Aeroengine oil tank fuel measurement technology was studied. First of all, the measuring method and principle of lubricating oil quantity in oil tank are outlined. On the basis of this, the oil secondary oil quantity analysis system of aeroengine is developed by UG secondary development. Through the system, the oil tank lubricating oil model of aeroengine is analyzed, and a three-dimensional database of the relationship between sensor oil immersion depth, aircraft attitude angle and oil volume is established, which provides a database for the real-time measurement of lubricating oil quantity in oil tank.
