摘要
型架外形设计涉及气动、结构以及气动同结构相互作用三个部分,通过使用Euler方程和雷诺平均N-S方程两种控制方程进行气动力计算,并将两组结果用于型架设计的气动输入,经过对比分析得到,气动力对型架设计有一定的影响,开发出更细致高效的气动力计算方法是提高型架设计准确性的重要部分。
Aerodynamics, structure modal analysis and the interaction of fluid and structure are three significant parts in wing jig-shape design. Aerodynamic force is evaluated by using Euler equation and RANS equation separately in this paper, A few differences in results are found in jig -shape analysis that uses different equations. The comparison shows that the efficient and accurate method of aerodynamic evaluation is important in wing jig-shape design.
