【摘要】：众所周知,发动机是飞机的心脏,保证发动机的高效工作就是保证了飞机的安全性与适航性。飞机维修费用占航空公司总成本的比例非常巨大,与此同时,发动机维修费用占据着飞机维修费用支出中最大的部分。因此,有效控制发动机的维修成本具有十分重要作用,由于发动机维修成本控制专业性强,涉面较广,并且国内航空公司对飞机发动机成本控制研究起步较晚,还处于摸索阶段,导致我国在飞机发动机维修成本控制方面,还远远落后于国际先进航空公司。本文以成本控制理论为基础,以CFM56型飞机发动机的维修成本为研究对象,通过对维修现状的梳理,分析该型号发动机维修成本方面存在问题,包括发动机运行可靠性降低,在恶劣运行环境下,部件损伤比较严重;发动机送修计划,在部分区域内无法充分发挥潜能;发动机无计划拆换数量较大,导致增加送修成本;发动机无差异的水洗工程,使发动机或是过度维修或是维修不足,从而影响发动机性能等方面。结合成本控制理论,提出以下解决方案:通过优化发动机送修时间控制和优化发动机深度维修模式,加强发动机维修过程中的成本控制;通过优化发动机送修的平衡点和发动机外包业务,树立正确成本维修理念;通过构建维修工程信息化系统和提升维修专业化管理水平,建立完善成本管理体系,从而降低发动机维护成本,为我国航空器维护成本控制方面做出一些贡献。
[Abstract]:As we all know, the engine is the heart of the aircraft, to ensure the efficient work of the engine is to ensure the safety and airworthiness of the aircraft. Aircraft maintenance costs account for a large proportion of the total cost of airlines, while engine maintenance costs account for the largest part of aircraft maintenance costs. Therefore, it plays a very important role in effectively controlling the maintenance cost of the engine. Because the engine maintenance cost control is professional and involves a wide range of areas, and the domestic airlines start the research on aircraft engine cost control relatively late. It is still in the exploratory stage, which leads to the fact that our country still lags far behind the international advanced airlines in the cost control of aircraft engine maintenance. Based on the theory of cost control and the maintenance cost of CFM56 aircraft engine, this paper analyzes the problems existing in the maintenance cost of CFM56 aircraft engine, including the reduction of engine reliability. In the bad operating environment, the damage of the components is more serious; The engine repair plan can not give full play to its potential in some areas, and the number of engine unplanned disassembly and replacement is large, resulting in an increase in the cost of repair. There is no difference in engine washing engineering, so that the engine is either overrepaired or underrepaired, thus affecting engine performance and so on. Combined with the cost control theory, the following solutions are put forward: by optimizing the engine repair time control and optimizing the engine depth maintenance mode, the cost control in the engine maintenance process can be strengthened; By optimizing the balance point of engine repair and engine outsourcing business, the correct cost maintenance concept can be established. By constructing the maintenance engineering information system and improving the maintenance professional management level, the cost management system can be established and perfected, so as to reduce the engine maintenance cost and make some contributions to the maintenance cost control of aircraft in our country.
