Title
(EN) ADJUSTABLE TURBINE VANES WITH SEALING DEVICE AND CORRESPONDING METHOD
(FR) AUBES DE TURBINE RÉGLABLES AVEC DISPOSITIF D'ÉTANCHÉITÉ ET PROCÉDÉ CORRESPONDANT
Abstract
(EN)
A turbomachinery component of a gas turbine engine is disclosed having a number of techniques of reducing the effects of a gap flow between an airfoil member of the gas turbine engine and a wall of the gas turbine engine. The airfoil member can be a variable and in one form is a variable turbine vane. In one embodiment a brush seal is included between the vane and the wall. In another form a wear surface is disposed between the vane and the wall. In yet another form a moveable member capable of being actuated to change position can be disposed between the vane and the wall to alter the size of a gap between the two.

La présente invention concerne un composant de turbomoteur d'un moteur de turbine à gaz présentant un certain nombre de techniques de réduction des effets d'un écoulement en fente entre un élément de surface portante du moteur de turbine à gaz et une paroi du moteur de turbine à gaz. L'élément de surface portante peut être variable et prend la forme, dans un mode de réalisation, d'une aube de turbine variable. Dans un mode de réalisation, un joint à brosse est compris entre l'aube et la paroi. Dans un autre mode de réalisation, une surface d'usure est disposée entre l'aube et la paroi. Dans un autre mode de réalisation encore, un élément mobile pouvant être actionné pour changer de position peut être disposé entre l'aube et la paroi pour modifier la taille d'un interstice entre ces deux éléments.
