摘要
针对计算流体力学 (CFD)软件在联结翼气动布局设计中应用的问题 ,研究如何快速、自动地生成 CFD软件所需的输入数据的方法。实现这一方法的要点有 :(1 )建立一个合理的联结翼飞机外形的参数化几何模型 ;(2 )基于这组参数 ,开发出能自动地生成 CFD软件 (MGAERO)所需输入数据文件的程序。计算实例表明 ,应用本文所提出的方法 ,可快速地对各种联结翼飞机方案进行气动特性分析 ,从而大大缩短了飞机方案设计中气动分析的时间。
Aimed at the application of CFD in the conceptual design of joined-wing aircraft, a method is presented for generating the input data for the CFD software MGAERO quickly and automatically. Two key issues concerned in this paper are as follows: (1) geometric description of the joined-wing aircraft configurations with a relatively small number of parameters; (2) development of a code to generate the input file of MGAERO based on these geometric parameters. Two applicational examples demonstrate that the method can save a considerable amount of time required for aerodynamic analysis of joined-wing configuration at conceptual design stage.
