The presently disclosed embodiments utilize an ice separator vessel to trap ice particles in a non-homogeneous ice/fuel mixture flowing in a fuel system. A source of heat, such as heated fuel provided to the ice separator vessel, is used to melt at least a portion of the ice particles so that they do not enter the fuel system downstream of the ice separator vessel.

L'invention a pour objet un dispositif d'atténuation d'ondes acoustiques formant la paroi d'un conduit ouvert, lesdites ondes acoustiques étant propagées par un flux d'air traversant ledit conduit, ledit dispositif comportant une structure (13) constituant un filtre acoustique, limitée par une première paroi ajourée formant la paroi interne (11) du conduit ladite première paroi présentant des perforations (15) faisant communiquer l'élément absorbant acoustique avec l'intérieur du conduit et par une seconde paroi pleine (12) formant la paroi externe du conduit. Le dispositif selon l'invention comporte en outre un jeu de canalisations (16) de transport de fluide caloporteur configurées et agencées vis-à-vis de la première paroi (11) du dispositif de façon à permettre un échange thermique, au travers de la première paroi, entre le fluide caloporteur et le flux d'air circulant dans le conduit.
摘要:
A flow vortex spoiler including an oil sump wherein pressurization air flow moves about the oil sump through a sump pressurization cavity, the cavity having an inlet, a circumferential plate disposed across a portion of the pressurization cavity near the inlet. The circumferential plate is disposed at said inlet to said sump pressurization cavity. The circumferential plate has a plurality of closely spaced apertures. The pressurization air has a radial component and a tangential component wherein the circumferential plate and the plurality of closely spaced apertures substantially reduce the tangential component of the pressurization air and further wherein the vortex spoiler inhibits excessive pressure change within the pressurization cavity and inhibits oil leakage at seals adjacent to the oil sump.

Es wird eine Tankvorrichtung (18) eines Flugtriebwerks (1) beschrieben, welche eine Einlasseinrichtung (30) zur Zuführung eines Luft-Öl-Volumenstroms in einen Tankraum (31) der Tankvorrichtung (18), eine Abscheideeinrichtung (32) zur Abscheidung von Öl aus dem dem Tankraum (31) zugeführten Luft-Öl-Volumenstrom, einen von wenigstens einer Wandung (37) begrenzten Leitungsbereich (38), in welchem ein Luft-Öl-Volumenstrom im Bereich des Tankraums (31) zumindest bereichsweise führbar ist, und eine Auslasseinrichtung (40) aufweist, in deren Bereich ein Volumenstroms über eine Ventileinrichtung (41) aus dem Tankraum (31) der Tankvorrichtung (18) abführbar ist. Es ist wenigstens eine Einrichtung (43) zum Einleiten von Öl vorgesehen, mittels welcher Öl im Wesentlichen entgegen einer sich im Betrieb ausbildenden Strömungsrichtung des Luft-Öl-Volumenstroms in dem Leitungsbereich (38) im Bereich des Leitungsbereichs (38) einleitbar ist.
摘要:
A turbine module comprises a turbine shaft, a rotor assembly secured to the shaft, a bearing assembly rotatably supporting the turbine shaft, and a bearing housing containing the bearing assembly. The bearing housing includes a gutter at least partially circumscribing the bearing assembly, and a drain disposed proximate a base of the gutter. The gutter includes a first sloped floor portion circumferentially adjacent to the drain.

A gearbox assembly for a gas turbofan engine includes a sun gear rotatable about an axis and a plurality of intermediate gears driven by the sun gear. A baffle disposed between at least two of the plurality of intermediate gears includes a first gap distance within a first gap portion and a second gap distance within a second gap portion. The first gap portion is disposed between the baffle and one of the intermediate gears away from the meshed interface with the sun gear and the second gap portion is disposed near the interface with the sun gear. The first gap distance within the first gap portion is different than the second gap distance within the second gap portion to define a desired lubricant flow path.
摘要:
Provided is a lubricant feed mechanism for a turbocharger, the mechanism that can reduce work of an oil pump while preventing an excessive supply of lubricant to a bearing part. The lubricant feed mechanism for a turbocharger 5, the mechanism of feeding lubricant to a bearing part 41 that rotatably supports a shaft 10 connecting a compressor wheel and a turbine wheel, includes: an oil supply passage 42 that guides the lubricant fed under pressure from the oil pump to the bearing part 41; and a flow control valve 50 provided to the oil supply passage 42 for adjusting the amount of the lubricant by throttling the flow passage of the lubricant based on a pressure of the lubricant flowing through the oil supply passage 42.
