High-precision prediction on unsteady aeroelastic loads of helicopter rotors under blade-vortex interaction condition

  • 摘要: 为准确计算直升机旋翼在复杂的桨-涡干扰(BVI)状态下的气弹载荷,在刚性旋翼计算流体力学方法中引入桨叶弹性变形的影响,建立了一套适合于弹性旋翼BVI状态气动特性分析的计算流体力学/计算结构力学(CFD/CSD)耦合方法.CFD模块对Reynolds averaged Navier-Stokes(RANS)/Euler方程进行求解,并采用双时间法推进和Baldwin-Lomax(B-L)湍流模型.CSD模块采用中等变形梁假设的有限元模型,通过Newmark-Beta方法求解桨叶运动方程.通过代数变换方法进行桨叶网格变形,并建立一个适于流场/结构信息交换的CFD/CSD耦合方法.在分别验证CFD和CSD模块的有效性的基础上,开展UH-60A直升机旋翼的BVI 状态载荷分析,并与飞行测试数据进行了对比.计算结果表明:相比于旋翼综合分析中的升力线理论和刚性旋翼CFD方法,耦合的CFD/CSD方法可以更准确地预测BVI状态气弹载荷,并有效地模拟桨叶前行侧方位角和后行侧方位角附近的BVI现象,对BVI导致的升力波动幅值和相位的计算结果均与试验值吻合良好.
