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.
