The study is devoted to the numerical simulation of flow around the rigid helicopter main rotor in forward flight based on the averaged Navier—Stokes equations in a noninertial reference frame. The calculations are performed using the in-house code NOISEtte, whose distinctive feature is the use of schemes with edge-based reconstruction of variables on unstructured mixed-element mesh, together with the commercial ANSYS CFX software package. The numerically obtained aerodynamic characteristics of the main rotor are compared with the data of physical experiment.

前飞刚性旋翼周围流动的数值模拟

该研究致力于基于非惯性参考系中的平均 Navier-Stokes 方程对前飞中刚性直升机主旋翼周围的流动进行数值模拟。计算是使用内部代码 NOISEtte 执行的，其显着特点是使用基于边缘的非结构化混合元素网格上的变量重建方案，以及商业 ANSYS CFX 软件包。将数值计算得到的主旋翼气动特性与物理实验数据进行对比。
