Effect of Distortion on Turbofan Tonal Noise at Cutback with Hybrid Methods
International Journal of Turbomachinery, Propulsion and Power, 2017 New ultra high bypass ratio architectures may significantly affect the fan tonal noise of future aircraft engines. Indeed, such a noise source is supposed to be dominated by the interaction of fan-blade wakes with outlet guide vanes.
