飞行程序设计在当前主要有两个研究方向,一是利用CAD等计算机软件,使飞行程序设计走向电子化和自动化,减轻设计者的工作负荷,确保设计的可行性;二是从飞行程序设计本身出发,将规章要求的内容与数学模型相结合,使得通过一系列条件的约束,最终可以求得一条或若干条满足规章要求的飞行航迹。本文将研究重点放在第二个方面,重点关注飞行过程中的起始进近航段,通过分析航段特点和规章要求,得到一系列以超障为目标的目标函数和约束条件。同时,为达到飞行程序设计多重目标的要求,本文分别从降噪和飞行经济性两方面入手,研究讨论了多目标下飞行程序设计的综合模型。
Flight program design in the current two main research directions, one is the use of CAD and other computer software, the flight programming to the electronic and automation, to reduce the workload of the designer to ensure the feasibility of the design; the second is from the flight programming itself In the beginning, combining the content of the regulations with the mathematical model, finally, one or several flight paths meeting the regulatory requirements can be finally obtained through a series of conditions. This paper focuses on the second aspect, with a focus on the initial approach flight segment during the flight. By analyzing the characteristics of the flight segment and the regulatory requirements, a series of objective functions and constraints aimed at the obstacle clearance are obtained. At the same time, in order to meet the requirements of multi-objective flight program design, this paper studies and discusses the comprehensive model of multi-objective flight program design from the aspects of noise reduction and flight economy respectively.
