Abstract:
In combination a wear indicator (100) and a component of a gas turbine engine is provided. The wear indicator (100) is secured to a surface (72) of the component of the gas turbine engine. The wear indicator comprising: a first side (120) delaminates when impacted by a blade (55) of the gas turbine engine; a second side (130) parallel to the first side (120), the second side (130) being secured to a surface (72) of the component of the gas turbine engine; a mid-section (140) interposed between the first side (120) and the second side (130); and a reference dimension remains constant when the first side (120) delaminates.
Abstract:
An injector element (1) of coaxial design is provided for a rocket drive for operation with a first and a second propellant, comprising a central body (5), a sleeve (2) and a flow splitter (7). The central body (5) comprises a flow channel with an outlet, the central body (5) generating a conical drop distribution at the outlet forming a fuel cone, wherein the first propellant, normally an oxidant, is provided in the central body (5). The sleeve (2) concentrically surrounds the central body (5) to form an annular flow channel for the second propellant, normally fuel. The flow splitter (7) is arranged between the central body (5) and the sleeve (2) for splitting the second propellant into a plurality of individual flows. The flow splitter (7) includes a given number of passage channels which are distributed around the central body (5), each of the passage channels for generating a fine propellant jet. The passage channels are slots (8) wherein the long sides of the slots (8) are inclined with regard to their radial extension to a longitudinal axis of the injector element (1).
Abstract:
A method of forming an annular support structure for fastening a component of a gas turbine engine to a static part of the engine is provided. The support structure has a substantially frustoconical skin portion which, in use, extends inwardly from the static part. The support structure further has a flange portion which extends inwardly from an inner edge of the skin portion. In use, a mating flange extending outwardly from the component is attached to the flange portion. The flange portion has an engagement face against which a corresponding face of the mating flange is secured. The flange portion further has an inwardly-facing land at an outer edge of the engagement face which restrains the component against radial movement. The method includes the steps of: providing a blank; flow-forming the blank over a mandrel into a near net-shape of the support structure; and removing excess material from the near net-shape to form the land and finish the support structure.
Abstract:
Ein erfindungsgemäßes Leitschaufelsegment 10 für eine Strömungsmaschine umfasst eine radial innere Deckplatte 13 mit einer Deckplattenoberfläche 14, die dazu eingerichtet ist, in der Strömungsmaschine einer dem Leitschaufelsegment benachbarten Laufschaufel 20 zugewandt angeordnet zu werden und dabei im Wesentlichen entlang einer Kegelmantelfläche K 1 zu verlaufen, deren Kegelachse mit der Rotationsachse A einer Rotorwelle 30 übereinstimmt. Eine erfindungsgemäße Laufschaufel 20 für eine Strömungsmaschine weist in einem radial inneren Bereich eine Grundplatte 23 mit einer Grundplattenoberfläche 24 auf, die dazu eingerichtet ist, in der Strömungsmaschine einem Deckband einer der Laufschaufel benachbarten Leitschaufelreihe 10 zugewandt angeordnet zu werden und dabei im Wesentlichen entlang einer Kegelmantelfläche K 2 zu verlaufen, deren Kegelachse mit der Rotationsachse A einer Rotorwelle 30 übereinstimmt.
Abstract:
The invention relates to a casing (10) for a gas turbine consisting of a composite material based on a fibrous reinforcement densified by a matrix. The casing (10) comprises at least one stiffening portion (17) extending according to a radius extending past the radii of the upstream and downstream portions (18, 19) of the casing, which are adjacent to said stiffening portion (17), in such a way as to form an annular cavity (171) on the inner surface (11) of the casing (10).
Abstract:
Bei Dichtringen für eine Labyrinthdichtung, die an einem rotationssymmetrischen Bauteil angebracht sind und in Reibkontakt mit einer stationären Einlaufschicht sind, ist der die Einlaufschicht kontaktierende Teil des Dichtringes (8) als auf einem Dichtringstumpf (14) aufgebauter Verschleißschutz-Ringabschnitt (15) mit in eine Metallmatrix (16) eingebetteten Verschleißschutzpartikeln (13) ausgebildet. Die Herstellung des Verschleißschutz-Ringabschnitts erfolgt durch Laserauftragsschweißen, wobei der Anteil der in dem einem Laserstrahl zugeführten Metallpulverstrom enthaltenen Verschleißschutzpartikel steuerbar ist.
