【摘要】：近年来我国通用航空产业迅猛发展,许多县市计划新建或正在新建通用航空机场。在新建机场时,机场设计特别是跑道长度需要根据执飞机型的性能来确定;在实际运营中,承运人也需要进行飞机性能分析。通航飞机性能计算量的增加,带来了开发通航机型飞机性能分析工具的迫切需求。运-12E(Y-12E)型飞机是我国通航机场的常用机型,本文对其飞机性能分析方法展开研究,对工作量大、耗时长、易出错的传统人工查询飞机性能手册的计算方式进行改进。以Y-12E型飞机飞行手册为计算依据,以中国民用航空规章(CCAR-23部)中通勤类飞机适航规定为规范,并结合成熟的飞机性能理论,研究开发了Y-12E型飞机性能分析软件。论文首先对Y-12E型飞机的起飞性能、着陆性能以及飞行计划进行分析。在飞机性能分析基础上,对飞机性能计算涉及到的有关数据处理和算法展开研究;在Y-12E型飞机性能数据的处理中,为将纸质图表进行数字化处理,利用Windows屏幕坐标与图像坐标的转换关系,开发了一套纸质图表的数字采样工具,实现了图表的导入、标定、数据读取和采集功能,加快了图表的数字化处理速度;进一步提出使用MATLAB自带的曲线拟合工具箱进行数据补全的方法,使用三角剖分算法和重心插值法进行插值计算,并利用MATLAB自带scarreredInterpolant函数进行方法和结果验证。论文接着进行Y-12E飞机性能软件的开发,该软件主要包括机场管理、起飞性能、着陆性能和飞行计划四个模块,详细分析了每个模块的功能和计算方法;基础性能表和机场信息采用SQLite数据库存储;整个软件利用C++语言在Qt框架下开发完成,模块化的架构开发思路保证了软件后续的维护和扩展。最后,论文分别以具体的实例,对起飞模块、着陆模块、飞行计划模块进行验证,得到的计算结果准确,说明Y-12E型飞机性能计算软件中性能计算方法无误,可以用做Y-12E型飞机性能分析工具。
[Abstract]:In recent years, China's general aviation industry has developed rapidly. Many counties and cities plan to build or are building new general aviation airports. When a new airport is built, the design of the airport, especially the length of the runway, should be determined according to the performance of the aircraft, and in actual operation, the carrier also needs to analyze the performance of the aircraft. With the increase of aircraft performance calculation, there is an urgent need to develop aircraft performance analysis tools. Yun-12E (Y-12E) aircraft is a common type of aircraft in China's navigable airport. This paper studies the performance analysis method of its aircraft, and improves the traditional manual calculation method of aircraft performance, which is time-consuming, time-consuming and error-prone. Based on the flight manual of Y-12E aircraft, the airworthiness regulations of commuter aircraft in China Civil Aviation regulations (CCAR-23), and the mature aircraft performance theory, a performance analysis software for Y-12E aircraft is developed. Firstly, the takeoff performance, landing performance and flight plan of Y-12 E aircraft are analyzed. On the basis of aircraft performance analysis, the data processing and algorithm involved in aircraft performance calculation are studied. In the processing of Y-12E aircraft performance data, in order to digitize the paper chart, a set of digital sampling tools of paper chart is developed by using the conversion relationship between Windows screen coordinate and image coordinate, and the chart is imported and calibrated. The function of data reading and collecting speeds up the digitization of charts and graphs. Furthermore, the method of data complement with curve fitting toolbox of MATLAB is put forward, the interpolation calculation is done by triangulation algorithm and barycenter interpolation method, and the method and result are verified by MATLAB scarreredInterpolant function. The thesis then develops Y-12E aircraft performance software, which mainly includes four modules: airport management, take-off performance, landing performance and flight plan. The functions and calculation methods of each module are analyzed in detail. The basic performance table and airport information are stored in SQLite database, and the whole software is developed with C language under the framework of Qt. The modular framework development idea ensures the subsequent maintenance and extension of the software. Finally, the paper verifies the take-off module, landing module and flight plan module with specific examples, and the result is accurate, which shows that the performance calculation method of Y-12E aircraft performance calculation software is correct. Can be used as Y-12 E aircraft performance analysis tool.
