Abstract
This paper is focused on gaining a deeper understanding on how different flight procedures relate to noise generation and how helicopter rotor noise may be abated. The paper describes a noise prediction system composed of a flight simulation model, a rotor airloads and airwake model, and a rotor noise prediction code which can be used to predict the helicopter rotor noise in various flight conditions. Using this system the noise is predicted for a variety of cases and then analyzed to determine how flight operation procedures can mitigate the noise levels. This system should provide guidance that may ultimately aid pilots, operators, and land use planners to determine flight operations and maneuvers that will produce less noise. The system developed is a physics-based system which quickly provides accurate noise and aerodynamic results. The computational speed of the system should also allow it to be incorporated into the design and analysis rotorcraft.
