航空仪表油的使用性能

The Properties of Lubricating-Oil in Use for Aviation Gyroscopes

对我国航空工业上使用的仪表油进行了蒸发特性、粘温特性、摩擦力矩、润滑性等使用性能的研究，评价了各油品的工作能力及长期使用性能，并与国外同类型油品进行了比较，提出了相应的使用牌号。

The Lubricating-oil in use for gyroscopes is one of lubricant materials on airplane. Its properties including evaporation, visco-temperature, friction moment and lubricity, are studied in this paper. The working and long-time in use capacity of various oil is evaluated.
