飞机结冰识别精度问题,针对结冰软件在模块集成和面向用户方面的特点,为了改善结冰性能的仿真计算,提高计算效率,研究了适用于结冰软件的开发方法,引入动态链接库思想和混合语言编程技术,将整个结冰计算过程实现模块化编程,并将各个模块转化为单独的动态链接库文件。根据MFC框架编写了控制模块计算的仿真平台,在平台中实现了数据存储、模块通信、结果显示等功能,同时引入了两种执行方式以适应多步长冰层增长的仿真。选取了NACA 0012翼型为计算模型,测试了所开发软件的计算能力,发现软件能够稳定地反复自动执行各个模块。研究发现,改进方法不仅提高了计算效率,而且各个模块程序也便于独立更新,同时很好地验证了结冰预测冰层增长的有效性和识别精度。
In order to improve the simulation performance of icing software and improve the computational efficiency, aiming at the problems of aircraft icing identification accuracy, aiming at the characteristics of icing software in terms of module integration and user orientation, this paper studies the development methods suitable for icing software and introduces the idea of dynamic link library And mixed-language programming techniques to modularize the entire icing calculation process and convert the individual modules into separate dynamic-link library files. According to the framework of MFC, the simulation platform of control module calculation is compiled. The functions of data storage, module communication and result display are realized in the platform. Two execution modes are introduced to adapt to the simulation of multi-step ice growth. The NACA 0012 airfoil is chosen as the computational model to test the computing power of the developed software and find that the software can stably execute the modules automatically and repeatedly. The research shows that the improved method not only improves the computational efficiency, but also facilitates the independent updating of each module program. At the same time, it validates the effectiveness and accuracy of icing prediction of ice growth.
