Abstract: A turbine blade, including an intrados wall, an extrados wall, at least one first radial trailing edge cavity, at least one second radial cavity upstream of the trailing edge cavity, an internal wall separating the radial cavities and with at least one channel connecting the cavities to one another, the channel being oriented in an axis intersecting the internal surface of the intrados wall.

Abstract: The present invention relates to the field of turbine blades for a turbo machine, in particular a turbine blade (1), including an intrados wall (2), an extrados wall (3), at least one first radial trailing edge cavity (4), at least one second radial cavity (5) upstream of the trailing edge cavity (4), an internal wall (6) separating the radial cavities (4 and 5) and comprising at least one channel (7) connecting the cavities (4 and 5) to one another, the said channel (7) being oriented in an axis (71) intersecting the internal surface (42) of the intrados wall (2).

Abstract: A gas turbine blade comprising an internal cooling circuit consisting of at least one cavity extending radially between the base and tip of the blade, at least one air inlet aperture at one radial end of the cavity and at least one air outlet orifice opening into the cavity and emerging onto one of the faces of the blade. At least one of the walls of the cavity of the cooling circuit comprises at least one air deflector whereof the shape and dimensions are adapted to project the air flowing along the wall of the cavity towards an opposite wall of the cavity whilst avoiding re-attachment of the boundary layer immediately downstream of the air deflector.
