飞机油耗性能直接关系到航空公司的运力调配与盈利程度。根据飞机实际飞行数据, 建立了指数衰减型的飞机油耗性能模型。基于油耗性能函数中各分量随飞行距离衰减速度不同的特性, 引入数据非一致性检测中的广义内积算法和RELAX信号分离迭代算法, 实现油耗性能函数各分量的分离和参数估计。CRB分析验证了参数估计算法的性能;A330飞机的飞行数据实验结果验证了指数衰减型油耗性能模型和参数估计方法的有效性。该方法为运输飞机油耗性能评估提供了一种参考准则。

The fuel consumption performance of aircraft is directly related to the deployment capacity and profitability of airline. According to the actual aircraft flight data, we established an exponential attenuation function model of aircraft fuel consumption performance. Based on the feature that the attenuation speed varies with each component of fuel consumption performance, the GIP algorithm of NHD and RELAX algorithm were introduced to realize the separation and parameter estimation of each component of fuel consumption model. The CRB analysis of the experiment results proved the accuracy of the parameter estimation, and the A330 flight data proved the effectiveness of the algorithm. This method provides a reference criterion for aircraft fuel consumption performance evaluation.
