Title: Hollow cooled blade or vane for a gas turbine engine
IPC: F01D5/18
Filed: 1973-10-13
Abstract: 1508571 Gas turbine blades - cooling ROLLS ROYCE Ltd 11 Oct 1974 [13 Oct 1973] 47917/73 Heading F1T A hollow cooled blade or vane for a gas turbine engine has an interior surface from which project a pair of inwardly extending ribs between which extends an apertured plate spaced from this interior surface and sealed to the blade or vane interior at the ribs, each rib being provided with a groove within which the plate engages. In the embodiment shown, a nozzle guide vane comprises inner and outer platforms 15, 16 and a hollow aerofoil portion 17 divided by a transverse partition 18 into a forward section 19 and a rearward section 20. In the wall of the forward section 19 are formed three longitudinal ribs 21, 22, 23 provided with longitudinal grooves 24, 25, 26, 27 into which are slotted apertured plates 28, 29. These plates engage with and seal against the inner platform 15 and are provided with further sealing ribs 30, 31 at their extremities adjacent the outer platform 16. Air fed to the upper surface of the platform 16, e.g. from the turbine compressor, flows into the forward section 19 and through the apertures in the plates 28, 29 in the form of jets to provide impingement cooling of the vane. The air then flows through film cooling holes 32, 33 to provide film cooling of the concave flank of the vane. In the rearward section 20, the air flows through a sinuous passage formed by the partition 18 and walls 34, 35 which extend from the platforms 16, 15 respectively and terminate just short of the opposite platforms, the air then leaving the vane through a trailing edge slot 36.

A package is made from two portions each made from a rigid laminated support, the portions being sealed together. The bottom portion 4 is made from a rectangular sheet of stiff paperboard 1 and covered with a coating or film 2 of vinylidene chloride, aluminium foil, nylon, polyester &c. The coating or film 2 may be covered with a layer 3 of polyethylene if the coating or film does not possess heat sealant properties. The upper portion is made from a paperboard blank 6 which has a central rectangular opening 7. A nylon film 9 is adhered to the circumference area of the blank 6 and extends over the central opening 7. The film 9 may be coated with "Saran" (Trade Mark) and be coated with a film of polyethylene for heat sealing purposes.

In a break-spinning-frame, to ensure that effective priming takes place when spinning is resumed, a photo-electric end detector 10 is provided in some of the units between the spinning chamber 4 and the Make-up mechanism 7, which a feeler-type director 9 is provided in all the units. The detectors 9 are made active when the start-button 11 is depressed, to stop the machine should the yarn break and are made inactive when the stop button is operated, while the detectors 10 are only made active when the stop-button 12 is depressed. Thus, when the spinning operation is stopped by the button 12, the withdrawal of yarn from the spinning-chamber continues until all the yarn is withdrawn, one of the detectors 10, each of which is disposed near the end of an outlet tube 5 of the spinning chamber, then sensing the end of the yarn, and stopping the take-up mechanism. Since substantially the same amount of fibre remains in each spinning chamber when spinning is stopped, the distance of the end from the corresponding take-up means is in all cases the same. Thus, for restarting, when a length is fed back from the winding-means by the automatic priming-means under the control of timing-mechanism or the feelers 9, it is made certain that the priming end will be united with the length extending from the spinning chamber.
