| 针对飞机维修手册中对空气涡轮起动机送修决策描述的不足，提出一种起动机送修及维护的定量决策方法。该方法依
据某型发动机起动机的可靠性数据建立有效的可靠性统计模型，并以此为基础引入可靠度1阶导数概念制定符合本机队的空气
涡轮起动机软时限；在进一步分析空气涡轮起动机维护成本的构成后，针对其中轴承失效所带来的高昂换修成本问题给出解决方
案；从部件换修成本和延误成本角度出发建立期望损失模型，以经济最优为目标给出定量的起动机维护检查间隔；以某航空公司
机队的起动机使用数据为例，计算起动机送修软时限和滑油检查间隔分别为26960和1915飞行小时。结果表明：该方法依据部件

| 英文摘要: |
| Aiming at the insufficiency of the aircraft maintenance manual for the description of the decision-making for the repair of
the air turbine starter，a quantitative decision-making method for the repair and maintenance of the starter was proposed. This method established an effective reliability statistical model based on the reliability data of a certain type of engine starter，and on this basis，the concept of the first derivative of reliability was introduced to formulate the soft time limit of the return for repair to the air turbine starter in line
with the fleet. After further analyzing the composition of the maintenance cost of the air turbine starter，a solution was given for the high replacement cost caused by the bearing failure. Then，based on the perspective of component replacement cost and delay cost，an expected
loss model was established，and a quantitative starter maintenance inspection interval was given with the goal of economic optimization. Finally，taking the starter usage data of an airline fleet as an example，the soft time limit for starter repair and the lubricating oil inspection
interval were calculated as 26960 and 1915 flight hours respectively. The results show that the method can formulate the starter soft time
limit and maintenance inspection interval suitable for the fleet based on the component reliability and maintenance cost data，which has a
certain engineering significance and application value. |
