摘要
燃油成本是航校进行通用教练机选型时的关键指标。由于飞行训练的复杂性,仅通过教练机的性能参数则难以反映真实的燃油消耗情况。鉴于此,分析了通用教练飞行训练过程中燃油消耗的特点,引入学习曲线构建了通用教练机燃油成本模型,采用SPSS软件对燃油消耗率进行单样K-S(Kolmogorov-Smirnov)检验,并对训练时间进行线性回归分析,通过蒙特卡洛法进行仿真分析。算例分析表明:此方法求出的通用教练机燃油成本近似期望值更为准确,所建立的模型具有应用价值,仿真方法便捷有效。
Fuel cost is a key indicator for the selection of general trainer aircraft in aviation schools.Due to the complexity of flight training,it is difficult to reflect the actual fuel consumption only through the performance parameters of the trainer.The characteristics of fuel consumption in the general coach flight training process was analyzed.The learning curve was introduced to construct the general trainer fuel cost model.SPSS software was used to perform single-sample Kolmogoorv-Smirnov(K-S)test on fuel consumption rate,and linear regression analysis on training time was performed.Simulation analysis was carried out by Monte Carlo method.The analysis of the example show that the fuel cost of the general trainer obtained is more accurate than the expected value.The established model has application value and the simulation method is convenient and effective.
