详细分析了影响更换发动机时间的不同因素,并通过在试飞阶段开展的专项试验,采用实测数据分析更换发动机工作项目的时序关系,建立更换发动机工作逻辑模型,直观反映出工作项目进度及相关关系,确定其关键工作项目,找出影响更换发动机时间的关键因素,为改进装备的维修性设计和规划保障资源提供辅助决策。
The different factors that influence the time of engine replacement are analyzed in detail. Through the special test carried out in the flight test phase, the measured data are used to analyze the timing relationship of the engine replacement project, the logic model of replacement engine work is established, the project schedule and related relationship are visually reflected, Identify the key work items, find out the key factors that affect the time of engine replacement, and provide auxiliary decision-making for improving maintenance design of equipment and planning and safeguarding resources.
