摘要
为自主研发我国的机载场面运行路径指引与告警系统,减少机场运行成本,保障机场运行安全,提出了一种新的航空器滑行速度分配模型和求解方法。分析航空器速度分配的初始信息,参考ICAO排放数据库对航空器滑行油耗进行建模,通过计算航空器滑行时的发动机推力系数能够求得对应的燃油流率,进而确定目标函数,建立航空器滑行速度分配模型,根据每个路段的初始速度和末速度分情况使用枚举法进行求解,求出最小滑行油耗对应的航空器在每个路段的滑行参数,进而求出整条滑行速度剖面,通过与已有文献的研究方法进行对比,验证了模型的有效性。
In order to independent research and development our country′s airborne scene operation path guidance and warning system,reduce the airport operating costs,ensure safe operation of the airport,a new kind of aircraft taxiing velocity distribution model and solving method is given.Firstly,the initial information of aircraft speed distribution is analyzed,and then the taxiing fuel consumption of aircraft is modeled according to ICAO emission database.The fuel flow rate can be obtained by calculating the engine thrust coefficient when the aircraft is taxing,and then the objective function can be determined to establish the aircraft taxing speed distribution model.According to the initial velocity and final velocity of each section,the enumeration method is used to solve the model,and the aircraft′s taxiing parameters corresponding to the minimum taxiing fuel consumption in each section are obtained.Finally,the whole gliding velocity profile is obtained,by comparing with the existing research method,the effectiveness of the velocity distribution model and the solving method proposed in this paper is proved.
