Abstract (en)

The blade has an internal cooling circuit with a cavity (24) extending radially between a blade base (12) and a blade tip (14). An air inlet aperture (34) is held at a radial end of the cavity and an air outlet orifice opening into the cavity. An air deflector (48) is shaped and dimensioned with an inclined ramp to project the air flowing along a wall (24a) of the cavity towards an opposite wall (24b). The deflector is held based on the flow that is centrifugal or centripetal, to project the air circulating in the cavity towards the wall of the cavity which is disposed on a concave side (20). Independent claims are also included for the following: (1) a gas turbine comprising a set of blades (2) a turbine engine comprising a gas turbine.
