Patent
CA 2200558
The present invention relates to a ducted axial fan for large diameter ducts. The invention is comprised of equidistantly spaced sensors upstream and downstream of the axial fan and spaced actuators located around the periphery of the duct to cancel tonal noise caused by the air turbulence generated by the rotation of the fan.
Ventilateur axial à enveloppe conçu pour des conduits à diamètre important (11) et comprenant des détecteurs (22, 23) placés à des positions équidistantes en amont et en aval d'un ventilateur axial, ainsi que des organes de commande (24, 26) placés autour de la circonférence dudit conduit afin d'annuler le bruit tonal provoqué par la turbulence de l'air produite par la rotation du ventilateur.
