[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.
