【摘要】：伴随着社会经济的快速发展,人员、货物的流动越来越频繁,民航运输正在我国的社会经济发展中扮演着重要作用。然而,伴随着发展,航班延误、交通拥堵、空域资源紧张等现象相继出现,此时就需要民航研究者进一步完善网络结构、拓展空域容量、提高空域利用率。空中高速路被发现成为解决这些问题的一种新途径,空中高速路是在一定空域范围内设计,一般在繁忙城市对间为性能较高的航空器提供一个单向、没有交叉的有着特定规则的独立隔离高速航路。当航空器在空中高速路中高速运行时,最容易发生冲突的行为之一则是航空器换道行为。因此,本文借鉴地面车辆换道行为研究的相关理论,结合空中高速路中航空器的运行特点,对空中高速路基本航路段中航空器的换道行为进行研究,论文主要工作如下:1、空中高速路航空器换道行为分析:首先对关于空中高速路概念、空中高速路规划的可行性、空中高速路的换道行为特性进行总结分析,再研究了航空人员特性、航空器特性、航路特性三种因素对换道行为的影响,为空中高速路的换道行为建模奠定了理论基础。2、航空器换道行为冲突距离建模:开始先对航空器换道过程进行了运动学分析,接着定义了碰撞冲突模型与最小冲突距离CSM,再研究航空器在换道时避免和周边航空器出现冲突的策略,最后基于最小冲突距离要求建立空中高速路的换道行为冲突距离模型。3、数据仿真和模型验证:应用Matlab对航空器换道模型仿真,根据最小安全冲突距离的理论分析计算,得出换道航空器分别实施匀速换道与加速换道两种策略时,换道航空器与相邻航空器不发生冲突的理论安全距离区域,并讨论了当航空器处于不安全冲突距离区域中时,采用何种加速度a_1调整自身位置进入安全冲突距离区域。
[Abstract]:With the rapid development of social economy, the movement of people and goods is becoming more and more frequent. Civil aviation transportation is playing an important role in the social and economic development of our country. However, with the development of flight delay, traffic congestion, space resource shortage and other phenomena, civil aviation researchers need to further improve the network structure, expand airspace capacity, and improve the utilization of airspace. The air highway is found to be a new way to solve these problems. The air highway is designed within a certain airspace, and generally provides a one way for the high performance aircraft in the busy city. Independent isolation of high speed routes with specific rules without intersections. When an aircraft is running at high speed on an air highway, one of the most likely conflicts is the change of course. Therefore, this paper uses the relevant theories of the research on the ground vehicle's change of track behavior, combining with the running characteristics of the aircraft in the air highway, to study the change behavior of the aircraft in the basic section of the air highway. The main work of this paper is as follows: firstly, the concept of air highway, the feasibility of air highway planning, the characteristics of air highway changing behavior are summarized and analyzed. The influence of three factors, namely, aeronautical personnel characteristics, aircraft characteristics and air route characteristics, on the changing channel behavior is also studied. It lays a theoretical foundation for the modeling of the change behavior of the highway in the air. 2. The conflict distance modeling of the exchange behavior of the aircraft. First, the kinematics analysis of the course of the change of track of the aircraft is carried out. Then we define the collision model and the minimum conflict distance (CSM,) to study the strategy of avoiding the collision with the surrounding aircraft when changing lanes. Finally, based on the requirement of minimum conflict distance, a collision distance model. 3, data simulation and model verification are established. The model is simulated by Matlab, and calculated according to the theory of minimum safe conflict distance. It is concluded that when the two strategies of uniform speed change and acceleration change are implemented separately, the theoretical safe distance between the changing aircraft and the adjacent aircraft is not in conflict, and when the aircraft is in the unsafe conflict distance region, it is discussed that when the aircraft is in the unsafe conflict distance region, What kind of acceleration a _ 1 adjusts its position into the security conflict distance area.
