Numerical simulation of rotor-fuselage-engine interaction in forward flight
This paper presents a study of the rotor-fuselage-engine interaction aerodynamics using CFD (computational fluid dynamics) numerical tools. With the application of the finite volume method, the incompressible N-S (Navier-Stokes) equations are solved on a multi-block body-fitted structured mesh. Rotor-fuselage interaction is investigated with the implement of actuator disk in the cases of ROBIN model and MI-171 helicopter. First of all, the accuracy of this viscous simulation is quantitatively validated by comparison with experimental data and previous reference. Furthermore, several flow field characteristics of MI-171 in forward flight with and without engines are discussed with the application of uniform actuator disc model and engine model. Eventually, non-uniform actuator disc model is applied for MI-171.
