摘要:

航空发动机价格昂贵、故障较多,保障人员仍采用经验预测需求,造成发动机短缺或者库存过度积压的问题经常发生。本文提出从到寿和随机故障产生的需求出发分析建立航空发动机的需求预测
模型,到寿产生的需求通过装机发动机的规定寿命、剩余寿命、单机飞行任务等计算,随机故障产生的需求通过损坏频率和不可靠度2种方法计算。算例表明航空发动机需求预测模型具有一定的准确性和
实用性。

关键词: 航空发动机, 需求预测, 损坏频率, 不可靠度

Abstract:

The price of aircraft engine was high, and its faults were many, security personnel still adopted experiences to forecast demand, which leaded to the lack of engine or
excessive backlog inventory occurring frequently. This paper puts forward a demand forecast model of aircraft engine by analyzing the demand caused by the engine to life and
random faults, through both ways of fault rate and frequency and unreliability to compute the demand caused by engine to life by aircraft engine’s specified life, remaining
life, single flight task and so on, and the demand caused by random faults. The example shows that the demand forecast model of aircraft engine is some accurate and practical.

Key words:  , aircraft engine; demand forecast; damage frequency; unreliability
