基于物理的仿真被广泛认为是一种在飞机设计定义的早期增加有关信息的方法,从而有助于避免设计改进时出现的意外问题。本文报告了在概念阶段评估自动使用计算流体动力学水平的空气动力学来编制飞行动力学分析表的努力。这些表用于计算操纵品质测量值。所涉及的方法问题是:a)从高层次的概念飞机描述中进行自动分析的几何和网格处理; B)采样和数据融合,以便及时计算大型数据表。用于说明方法的测试用例是基于改进设计的客机风洞模型。这个模型被减少到一个概念性的描述,这个几何形状的能力,允许相关的最终设计的计算被绘制,然后检查。然后生成数据表并计算操纵品质。
Physics based simulation is widely seen as a way of increasing the information about aircraft designs earlier in their definition, thus helping with the avoidance of unanticipated problems as the design is refined. This paper reports on an effort to assess the automated use of computational fluid dynamics level aerodynamics for the development of tables for flight dynamics analysis at the conceptual stage. These tables are then used to calculate handling qualities measures. The methodological questions addressed are a)geometry and mesh treatment for automated analysis from a high level conceptual aircraft description and b) sampling and data fusion to allow the timely calculation of large data tables. The test case used to illustrate the approaches is based on a refined design passenger jet wind tunnel model. This model is reduced to a conceptual description, and the ability of this geometry to allow calculations relevant to the final design to be drawn is then examined. Data tables are then generated and handling qualities calculated.
