Numerical Study on Aerodynamic and Noise Responses of Rotor with Ramp Increase in Collective Pitch Based on Time-Accurate Free-Wake Method

Numerical Study on Aerodynamic and Noise Responses of Rotor with Ramp Increase in Collective Pitch Based on Time-Accurate Free-Wake Method

Research on helicopter transient maneuvering flight noise is a hotspot and challenging topic in the fields of helicopter design and application. A new time-accurate free-wake (TAFW) method and the Fowcs Williams-Hawkings (FW–H) equations are applied to analyze the aerodynamic and noise responses of...
