| description | A sump pressurization system for a gas turbine engine comprises a first hollow shaft and a second hollow shaft disposed within the first hollow shaft and defining a cavity therebetween. Each of the first and second hollow shafts has a common axis of rotation. Also included is a source of pressurized air to pressurize the cavity and a plurality of hollow tubes disposed in the cavity. The tubes are oriented perpendicular to the axis of rotation and are connected to and rotatable with the first hollow shaft. A plurality of apertures in the second hollow shaft are in fluid communication with the tubes, such that pressurized air flowing through the tubes passes through the apertures into the interior of the second hollow shaft.
Un système de mise sous pression de carter pour un moteur à turbine à gaz comprend un premier arbre creux et un second arbre creux disposé à l'intérieur du premier arbre creux et définissant une cavité entre eux. Chacun des premier et second arbres creux comprend un axe de rotation commun. L'invention comprend également une source d'air sous pression permettant de mettre la cavité sous pression et une pluralité de tubes creux disposée dans la cavité. Les tubes sont orientés perpendiculairement à l'axe de rotation, sont raccordés au premier arbre creux et sont rotatifs avec celui-ci. Plusieurs ouvertures dans le second arbre creux sont en communication fluidique avec les tubes de sorte que l'air sous pression s'écoulant à travers les tubes traverse les ouvertures à l'intérieur du second arbre creux. |
