【摘要】：大型客机高速气动设计需融入型号的设计经验、准确的数值分析方法以及高效的全局优化流程。将型号研制积累的设计经验及准则与现有数值计算工具、优化算法和计算机硬件资源相结合,探索发展了基于CFD的大型客机气动优化设计综合方法,该方法系统综合全局优化与局部寻优、人工经验与数值优化、参数化方法和参数控制以及自动化网格生成等方法和技术,大幅提升了气动设计效率。同时,完善了工程中实用的大型客机高速气动设计方法和流程,设计过程中融入了气动、结冰、静气动弹性等多专业的综合约束,反映了机翼设计多学科综合的本质特征,有助于形成综合最优的设计方案。以大型客机的超临界机翼优化设计为例,叙述了其在高速气动设计工作中的应用。
[Abstract]:The high-speed aerodynamic design of a large airliner needs to incorporate the design experience of the model, the accurate numerical analysis method and the efficient global optimization process. The design experience and criterion accumulated in the development of the model are combined with the existing numerical calculation tools. Based on the combination of optimization algorithm and computer hardware resources, a comprehensive method of aerodynamic optimization design for large passenger aircraft based on CFD is developed. The method integrates global optimization with local optimization, artificial experience and numerical optimization. Parameterized method and parameter control, automatic grid generation and other methods and technologies have greatly improved the efficiency of aerodynamic design. At the same time, the practical high-speed aerodynamic design method and process of large passenger aircraft have been improved. The integrated constraints of aerodynamics, icing, static Aeroelasticity and so on are incorporated in the design process, which reflects the essential characteristics of multi-disciplinary synthesis of wing design. Taking the supercritical wing optimization of large passenger aircraft as an example, its application in high-speed aerodynamic design is described.
