摘要

最近，已采取步骤将合成碳氢化合物作为生物成分引入航空燃料。这一行动是航空燃料处理方法的创新变革。这种评估燃料性能的新方法需要修订现有的质量评估标准，包括与摩擦学性能有关的标准。在喷气燃料要求中，仅采用模拟连续圆周运动的BOCLE试验来评估润滑性。对含有高度不同化学成分成分的燃料的使用研究表明，BOCLE试验可能不足以评估飞机涡轮发动机燃料的润滑性。提出了一个额外的HFRR试验，该试验模拟了燃油系统某些润滑元件中伴随往复摩擦的过程。本文介绍了一系列Jet A1燃料混合物和各种合成石蜡烃的BOCLE和HFRR测试结果。对观察到的合成烃对两种试验结果的影响作了初步分析。

THE INFLUENCE OF SYNTHETIC HYDROCARBON ON LUBRICATING PROPERTIES OF FUELS FOR TURBINE ENGINES

Recently, steps have been taken to introduce synthetic hydrocarbons to aviation fuels as biocomponents. This action is an innovative change in the approach to aviation fuels. This new approach to the assessment of fuel properties requires a revision of the existing criteria for their quality assessment, including those relating to tribological properties. In the requirements for Jet fuel, only the BOCLE test simulating continuous circular motion was used to assess lubricity. Research on the use of fuels containing components with highly differentiated chemical compositions indicate that the BOCLE test may be an insufficient criterion for assessing the lubricity of fuels for aircraft turbine engines. An additional HFRR test modelling the processes accompanying the reciprocating friction that occurs in some lubricated elements of the fuel system has been proposed. This article presents the results of BOCLE and HFRR tests on a range of Jet A1 fuel mixtures and various synthetic paraffin hydrocarbons. A preliminary analysis of the observed effect of synthetic hydrocarbons on the results of both tests is presented.
