Abstract
(DE)
Gegenstand der Erfindung ist eine Vorrichtung zum Reinigen der Core Engine eines Strahltriebwerks, mit einer Düseneinrichtung, die zum Einbringen von Reinigungsmedium in die Core Engine ausgebildet ist und Mittel zur drehfesten Verbindung mit der Welle des Fans des Strahltriebwerks aufweist; und mit einer Leitungsverbindung (10) zum Zuführen von Reinigungsmedium, die über eine Drehkupplung (8) mit der Düseneinrichtung verbunden ist. Erfindungsgemäß ist vorgesehen, dass die Düseneinrichtung erste Anlägeflächen (5) zur axialen Anlage an den Fan Blades (4) aufweist, die zur definierten Positionierung der Düseneinrichtung relativ zum Strahltriebwerk ausgebildet sind.
(EN)
The invention relates to a device for cleaning the core engine of a jet engine, comprising a nozzle unit designed for introducing cleaning medium into the core engine and having means for rotationally fixing to the shaft of the fan of the jet engine; and comprising a line connection (10) for supplying cleaning medium, which is connected to the nozzle unit via a rotary coupling (8). According to the invention, the nozzle unit has first contact surfaces (5) for axially contacting the fan blades (4), which are designed for the defined positioning of the nozzle unit relative to the jet engine.
(FR)
L’invention concerne un dispositif pour le nettoyage du moteur central d’un moteur à réaction, comprenant un dispositif à buse conçu pour l’introduction d’un produit de nettoyage dans le moteur central et des moyens pour le raccordement solidaire en rotation avec l’arbre de ventilateur du moteur à réaction ; et comprenant un raccordement de conduite (10) pour l’amenée de produit de nettoyage, lequel est raccordé au moyen d’un accouplement rotatif (8) au dispositif à buse. Selon l’invention, le dispositif à buse comprend des premières surfaces d’appui (5) pour l’appui axial sur les pales de ventilateur (4), qui sont conçues pour le positionnement défini du dispositif à buse par rapport au moteur à réaction.
