ABSTRACT:
A vane for a turbojet engine, is disclosed having an airfoil-shaped body with a leading edge, a trailing edge, a generally concave sidewall and a generally convex sidewall defining a hollow vane interior. A cooling air supply duct extends substantially over the entire length of the vane and communicates with a turbulence chamber in the vicinity of the leading edge which is separated from the supply duct by a partition having air cooling orifices to allow the air to pass from the cooling air supply duct into the turbulence chamber. The air from the turbulence chamber is evacuated through evacuation orifices defined by the generally convex sidewall in the vicinity of the leading edge. A plurality of heat exchange members are located in the interior of the vane such that they are spaced apart, extend substantially parallel to each other and substantially perpendicular to a longitudinal axis of the vane. The heat exchange members have downstream edges located adjacent to the trailing edge of the vane and upstream edges, which define a portion of the cooling air supply duct. Each of the heat exchange members is in heat exchange contact with the generally concave sidewall and the generally convex sidewall and are spaced apart by spacing ribs interposed beween adjacent heat exchange members.
