Numerical Simulation of Flow around Rigid Rotor in Forward Flight

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.
