摘要
文章根据重油二冲程航空发动机的运行工况及重油二冲程航空发动机与普通小型二冲程发动机情况的对比,初步确定了重油二冲程无人机发动机油的性能特点.无人机润滑油使用性能评价结果显示:与专用油相比FD和TC-W3油存在燃烧室积炭严重的问题,不能满足无人机的润滑需求;通过红外光谱和扫描电子显微镜等手段对专用油和积炭进行结构和元素分析,确定专用油的可能组成,并对专用油的开发提出建议,以加快国产化进程.
Abstract
This paper preliminarily identifies the performance characteristics of oil products based on the operating conditions of heavy oil two-stroke UAV engines and the comparison between the heavy oil two-stroke UAV engine and conventional small two-stroke engine.The performance evaluation results of lubricating oil for UAV engines show that FD and TC-W3 oils exhibit severe carbon buildup in the combustion chamber compared to dedicated oils,failing to meet the lubrication needs of UAVs.Structural and elemental analyses of the dedicated oil and carbon deposits were conducted using infrared spectroscopy and electron microscopy,identifying the possible composition of the dedicated oil.Recommendations for the development of dedicated oil are provided to expedite the localization process.
