| 摘 要： | 基于飞行状态造成的疲劳损伤，引入“影响因子”的概念，建立飞行状态时间比例改变对动部件使用费用影响的数学模型，分析各种飞行状态时间比例改变对动部件使用费用的影响程度。采用此模型对某型直升机的研究表明，计算得到的只有一个飞行状态时间比例主动改变和只有一个飞行状态时间比例未主动改变的影响因子可以定性和定量地分析飞行状态对使用费用的影响，在此型直升机所有的飞行状态巾只有两种飞行状态造成的使用费用在飞行状态时间比例变化0．1时变化超过0．01。

| Abstract: | Based on the fatigue damage by flight conditions, an analytical model was presented for the calculation of influence of flight time proportion changes on the operation cost of helicopter components by introduced influence factor. Two influence factors for the cases where only one flight condition was modified at a time and all flight conditions except one were modified could provide qualitative ordering and quantitative assessment of flight condition changes on operation cost. Some results were obtained by ... |
