军用飞机可维护性和可维修性对作战效能的影响

The Effect of Maintainability and Repairability on Military Aircraft Operational Effectiveness

从机群作战行动平均动态方程出发 ,以飞机重量平衡方程为基础 ,建立描述飞机在整个战斗飞行过程中 ,作战效能与为保证飞机有良好的可维护性和可维修性所附加的非受力结构面积之间关系的数学模型 ,该模型定量地反映了飞机可维护性和可维修性对作战效能的影响 。

For improving operational effectiveness of Chinese military aircraft, we deem it necessary to study the effect of maintainability and repairability. We derived eqs.(1) through (7) to describe the mathematical model relating operational effectiveness index with average time required for maintenance and repair. We also derived eqs.(8) through (13) to describe the mathematical model relating the weight of unstressed structure to operational effectiveness index. We applied the method to a numerical example. Figs.1 and 2 show the variation of operational effectiveness index with β and respectively, where β and are two factors related to the weight of unstressed structure. Figs.1 and 2 are then used to optimize the weight of unstressed structure.
