目前民机成功设计的一个关键要素即在设计中有效地引入计算流体力学(CFD)的模拟方法和软件,特别是具有设计能力的方法和工具。本文概要地叙述了反设计、基于CFD低可信度和高可信度模型等数值优化方法的发展和应用于民机设计的历史和现状;简单地介绍了即将举行的空气动力优化设计计算系列研讨会;重点讨论了对可应用于民机设计的基于Navier-Stokes方程解算器的OPTIMAS的数值优化方法的要求及其构造方法,并以翼身组合体整流外形和翼身融合体(BWB)外形的算例表明其有效性,说明OPTIMAS可以成为民机日常设计的方法和工具之一。
At present, a key element of the successful design of civil aircraft is the effective introduction of simulation methods and softwares for computational fluid dynamics (CFD) in the design, especially those with design capabilities. This paper presents an overview of the history and current status of reverse engineering, numerical optimization based on CFD low confidence and high reliability models, and its application in civil aircraft design. It briefly introduces the upcoming series of Aerodynamic Optimization Design Computation Seminars. The requirements and construction methods of OPTIMAS numerical optimization method based on Navier-Stokes equation solver which can be applied to civil aircraft design are discussed. In the meantime, BWC (BWB) ) The appearance of the example shows its effectiveness, indicating OPTIMAS can become one of the methods and tools for daily design of civil aircraft.
