摘　　要：为了满足喷气客机多方面的设计要求和目标,开发了总体参数优化计算环境。基于工程算法,研究了几何、动力、重量、气动、性能、操稳和成本的分析模型,并开发了相应的计算模块;通过集成各专业分析模块,建立了喷气客机总体综合分析模型;在探讨了喷气客机总体参数优化模型的基础上,应用iSIGHT平台集成喷气客机总体综合分析模型,建立了喷气客机总体参数优化计算环境。典型算例验证了喷气客机总体参数优化计算环境的可行性和有效性,从而为设计人员快速确定喷气客机总体参数提供了一个有效的工具。In order to meet the design requirement and aim of civil jet,a computing framework optimization of civil jet conceptual design is developed.Based on the empirical methods of the individual disciplines including geometry,propulsion,mass,aerodynamics,performance,control and cost,the computer codes for each discipline are developed.The global analysis code for civil jet conceptual design is obtained by integration of the codes for each discipline,and an integral conceptual design analytical model is presented.A computing framework for optimization of civil jet conceptual design is established through integration of the global analysis code into the software iSIGHT.A typical example is used to verify the feasibility and effectiveness of the framework for optimization of civil jet conceptual design.The framework developed in this research can be used as an effective tool for designers to quickly determine the primary parameters during the phase of civil jet conceptual design.
