Abstract

In this work, rotors with artificial ice shapes are studied to develop an insight into the potential of acoustics-based ice detection. Using the Helicopter Multi-Block CFD solver, approximate ice shapes are added to the blades and the results are analyzed using the Ffowcs Williams–Hawkings method. Several candidate monitoring positions are assessed for acoustic sensors to be placed on the helicopter fuselage. The influence of ice on the aero-acoustic characteristics of a rotor is calculated, and parameters such as the ice amount and the icing position on the blade are quantified. It is concluded that an array of microphones is best for detecting potential icing position on the blades, and it should be located on top of the helicopter rear fuselage and along the tail-boom.
