摘要

为提高不同型号发动机滑油中断试验的成功率，基于GJB 241A-2010标准，根据大、中型运输机与战斗机不同的工作特点，对比研究了不同涵道比发动机实现模拟瞬时滑油流量中断的试验方案。因使用条件、适航要求、判定标准的不同，导致大小涵道比不同的发动机调试方案和考核方案存在一定的差异。依据滑油中断试验中未恢复供油和发动机喘振等典型故障下各系统所呈现的工作模式，结合特定试车场景下可能存在的风险制定相应的应对措施，为不同型号发动机开展滑油流量中断考核试验提供借鉴。

Abstract

To improve the success rate of oil interruption tests for different types of engines， based on the GJB 241A-2010 standard and according to the working features of large and medium transport aircraft and fighter aircraft， the test scheme of simulating instantaneous oil flow interruption of engines with different bypass ratio was compared and studied. Due to differences in service conditions， airworthiness requirements， and judgment criteria， there were differences between the commissioning scheme and the assessment scheme of engines with different bypass ratios. According to the working modes of each system under typical faults such as failure to restore oil supply and engine surge in the oil interruption test， and combined with the potential risks in specific test scenarios， corresponding countermeasures are formulated to provide reference for different types of engines to carry out the oil flow interruption test.
