摘要
航空发动机基层级平均修复时间是影响飞机战备完好性的重要指标,在进行发动机维修性设计时需将该指标合理地分配至各附件,以明确各附件维修性设计定量指标要求。传统的以考虑故障率因素为主的分配方法的结果与工程实际维修数据严重背离,附件研制单位难以承接分配指标,因此本文基于系统工程思维,研究了一种基于功能复杂度的平均修复时间分配方法,通过对维修性设计要素和实现途径,如拆卸安装、检测隔离以及检验调试等几方面进行分析,对维修接口的复杂度进行定量评估,进而确定各分配对象的平均修复时间,该方法将设计对象功能模型与维修性模型深度关联,保证了修复时间分配指标的设计可实现性,可有效用于整机维修性指标的分配。
The average repair time of the grassroots level of aero engines is an important indicator affecting the combat readiness integrity of aircraft.When conducting the maintainability design of engines,this indicator should be reasonably allocated to each accessory to clarify the quantitative maintainability design requirements of each accessory.The traditional allocation method mainly considering the failure rate factor has a serious deviation from the actual maintenance data in engineering,and the accessory development units find it difficult to undertake the allocated indicators.Therefore,this paper studies a method for allocating the average repair time based on functional complexity from the perspective of systems engineering.By analyzing the maintainability design elements and implementation approaches such as disassembly and installation,detection and isolation,as well as inspection and debugging,the complexity of the maintenance interface is quantitatively evaluated.The average repair time of each allocation object is determined based on the complexity of the maintenance interface.This method deeply correlates the functional model of the design object with the maintainability model,ensuring the design feasibility of the repair time allocation indicators and can be effectively used for the allocation of the overall aircraft maintainability indicators.
