Active cancellation of rotor/stator interaction tones in turbofan engines

Rotor/stator-generated aerodynamic noise in turbofan engines, HVAC axial fans, and other turbomachinery is often dominated by blade passage harmonics produced by dipole sound sources. Radiation toward the inlet and exhaust depends upon the effective orientation of the dipole sources relative to the...
