【摘要】：中国的经济正在飞速发展,人们选择飞机作为交通工具的机会越来越多,民航运输业因其国际性,快速省时等特点越来越博得人们的关注,这也就使得空中交通越来越拥挤。飞机数量的增多使飞行成本的控制对航空公司而言显得格外重要。与此同时,为了保证飞行的安全和通畅、实时掌握飞行的动态,提供更确的航空器四维航迹飞行信息也显得尤为重要。本文首先基于性能计算的角度,介绍飞机性能计算的原始数据(如大气特性、气动特性和发动机特性),又分阶段介绍飞机性能的计算方法。然后基于能量状态法对性能理论以及算法进行了研究分析,通过分析飞机的运动学方程,结合飞机能量状态对飞机的运动方程进行了简化处理,最后得到最小成本时的航迹特征。在四维航迹方面,首先介绍了四维航迹的相关概念,然后建立航迹预测计算模型,利用收集到的飞行计划报和实时电报等数据,运用极大似然估计法对飞行参数进行拟合,将所得结果代入计算模型即可得到航空器的四维航迹信息。本文的结果可为四维飞行管理系统的构建提供有效的帮助,最后对应用前景做了展望。
[Abstract]:With the rapid development of China's economy, people have more and more opportunities to choose aircraft as a means of transportation. Civil aviation industry has attracted more and more attention because of its international, rapid and time-saving characteristics, which makes air traffic more and more congested. The increase in the number of aircraft makes the control of flight costs particularly important for airlines. At the same time, in order to ensure the safety and smooth flight, it is very important to grasp the flight dynamics in real time and provide more accurate flight information of the four-dimensional flight track. This paper first introduces the original data of aircraft performance calculation (such as atmospheric characteristics, aerodynamic characteristics and engine characteristics) based on the point of view of performance calculation, and then introduces the calculation method of aircraft performance in stages. Then the performance theory and algorithm are studied and analyzed based on the energy state method. By analyzing the kinematics equation of the aircraft and combining the energy state of the aircraft, the motion equation of the aircraft is simplified. Finally, the track characteristics of the minimum cost are obtained. In the aspect of four-dimensional track, the related concepts of four-dimensional track are introduced, and then a flight path prediction model is established. The maximum likelihood estimation method is used to fit the flight parameters using the collected data such as flight plan and real-time telegram. The four-dimensional track information of the aircraft can be obtained by substituting the obtained results into the computational model. The results of this paper can provide effective help for the construction of four-dimensional flight management system. Finally, the prospect of application is prospected.
