摘要
本研究以C、JAVA和MATLAB混合编程技术搭建多层次的民用飞机概念设计程序平台,并将经济性指标有机融合到概念设计流程中。在全面分析飞机概念设计参数间的传递关系的基础上,综合了直接运营成本、重量、几何布局、气动、性能、噪音排放等飞机概念设计模块。通过主要参数的影响分析,对比了发动机油耗,复合材料应用对经济性的传递影响。利用该程序将能对飞机进行较为全面的面向经济性的概念设计和先进技术对经济性的影响分析。
In this paper, a mixed-language programming approach based on C, JAVA, and MATLAB was developed to integrate direct operating cost model into a multi-level civil aircraft conceptual design program. Based on the comprehensive analysis of transfer relationship in aircraft conceptual design parameters, the program implemented DOC module as well as those typical analysis models in aircraft sizing procedure, including weight, geometrical configuration, aerodynamics, performance, noise and emission models. By analyzing the influence of main parameters, we compared the engine fuel consumption and analyzed the impact of composite material application on the economy. This DOC-driven civil aircraft conceptual design framework can be used as a design tool to perform parametric analysis and to evaluate the economic impact of new technologies.
