    摘要: A transpiration-cooled turbine vane has a porous wall and an internal strut with a slidable dovetail connection to the wall to reinforce the wall. The dovetails may be directly on the wall or on a fluid distributing plate bonded to the wall. This fluid distributing plate, if present, or the strut provides for metering flow of cooling air to some areas of the wall.

    摘要: A turbine rotor blade of laminated porous metal cast into a base includes an inner reinforcing layer which has increasing porosity in the direction spanwise of the blades so that the strength diminishes with load in the spanwise direction and the porosity provides for flow of air to the porous blade wall. Pores or relieved areas in some sections of some layers are elongate and disposed with their long dimension spanwise of the blade for increased strength in this direction, in which stress in the blade is greatest.

    摘要: A turbine blade includes a hollow airfoil integrally joined to a dovetail. The airfoil includes a perforate first bridge defining a flow channel behind the airfoil leading edge. A second bridge is spaced behind the first bridge and extends from a pressure sidewall of the airfoil short of the airfoil trailing edge. A third bridge has opposite ends joined to the pressure sidewall and the second bridge to define with the first bridge a supply channel for the leading edge channel, and defines with the second bridge a louver channel extending aft along the second bridge to its distal end at the pressure sidewall.

    摘要: A perforated sheet for the promotion of film cooling a gas turbine engine comprises two separate layers of laminate material which are placed in superposed abutting relationship. The first layer has a plurality of apertures of given cross-sectional area therein. The second layer also has a plurality of apertures therein which have larger cross-sectional areas than the corresponding apertures in the first layer. The apertures in the first layer are in fluid communication with the apertures in the second layer to form passageways through the perforated sheet. These passageways permit a cooling flow of fluid to pass through the perforated sheet so it can be discharged as a cooling fluid film along the inner surface of the perforated sheet. The apertures in each layer are independently formed to produce the passageways. The apertures can easily be machined to the desired size, shape, and angle to optimize the cooling film effectiveness for any particular application.
