Title (EN) AXIAL FAN BLADE WITH WAVY AIRFOIL AND TRAILING EDGE SERRATIONS
(FR) PALE DE VENTILATEUR AXIAL AYANT UNE SURFACE PORTANTE ONDULÉE ET DES DENTELURES DE BORD DE FUITE
Abstract:
(EN) An axial flow fan includes a hub rotatable about a fan axis and a plurality of fan blades mounted to the hub. One of the plurality of fan blades includes at least one wave extending in a span wise direction over the fan blade and at least one serration extending along a trailing edge of the fan blade. The at least one wave and the at least one serration are arranged at a location between 40% and 100% of a span of the fan blade.
(FR) L'invention concerne un ventilateur à flux axial comprenant un moyeu pouvant tourner autour d'un axe de ventilateur et une pluralité de pales de ventilateur montées sur le moyeu. L'une de la pluralité de pales de ventilateur comprend au moins une onde qui s'étend dans une direction d'envergure sur la pale de ventilateur et au moins une dentelure qui s'étend le long d'un bord de fuite de la pale de ventilateur. Ladite onde et ladite dentelure sont agencées au niveau d'un emplacement situé entre 40 % et 100 % d'une envergure de la pale de ventilateur.
