Abstract
The present invention relates to blading () for a turbomachine (), comprising: —a blade () having an aerodynamic profile; —a platform () comprising a flow-path surface () intended to delimit a primary flow path (A) of the turbomachine (), which path is intended, when the turbomachine () is in operation, to receive a flow that splits, upstream of the blade (), into a suction-face flow (EE) and a pressure-face flow (EI); and —an internal canal () which has an intake opening () and an ejection opening (), these each opening onto the flow-path surface () of the platform (), the ejection opening () opening downstream of the intake opening () and the intake opening () opening toward the pressure-face flow (EI).
