Analysis of civil aircraft aerodynamic characteristics with powered effects based on CFD/CSD method

  • 摘要: 基于Reynolds average Navier-Stockes(RANS)的三维Navier-Stokes流场控制方程耦合结构静力学方程时域分析方法,研究了带有发动机的民用飞机其动力效应对全机气动性能的影响。首先采用数值方法对发动机进排气边界条件进行了模拟,分析了带动力的涡扇发动机模型的流场,并将计算结果与实验进行比较,验证边界条件处理的准确性;以此为基础,考虑结构弹性变形,采用计算流体动力学/计算结构动力学(CFD/CSD)耦合的方法,分别对通气和带动力的翼吊发动机全机的气动性能进行了研究。结果表明:基于通气构型预测的升阻力系数,气动载荷和压心位置与考虑动力效应后的计算结果存在明显不同。弹性变形又会加剧这一差异,使得全机的升阻比下降约12.6%,升力系数下降约8.9%,压心位置后移。数值算例显示,在靠近发动机区域气动载荷受动力效应影响显著,远离该区域,弹性变形效应占主要影响因素,因此在进行带动力效应的民机气动性能分析时,考虑弹性变形的影响是十分必要的。
