Investigation on Aerodynamic Noise Characteristics of Coaxial Rotor in Hover

Investigation on Aerodynamic Noise Characteristics of Coaxial Rotor in Hover

A numerical method based on Reynolds Averaged Navier–Stokes (RANS) equations and a high-efficiency trim model is developed to simulate the aerodynamics of a coaxial rotor. Farassat 1A equations are used for the prediction of thickness and loading noise. Hover cases of different thrust coefficients w...
