Abstract

Dispositif de prise d'air du compresseur des moteurs à turbine à gaz qui sont équipés d'au moins une grille directrice de compresseur réglable et parcourue par un flux axial, ce dispositif étant caractérisé en ce que : a. l'air du compresseur est prélevé dans la région du moyeu, au droit de la paroi intérieure du conduit de la veine du compresseur et transmis à un appareil consommateur à travers les aubes directrices creuses de la grille directrice réglable, ainsi qu'à travers les plateaux et tourillons de ces aubes ; b. les aubes directrices de la grille directrice réglable tourillonnent uniquement dans le carter extérieur du compresseur ou dans le carter extérieur du moteur, suivant une construction connueDevice for taking air from the compressor of gas turbine engines which are equipped with at least one adjustable compressor guide grille traversed by an axial flow, this device being characterized in that: a. the compressor air is taken from the region of the hub, in line with the inner wall of the duct of the compressor duct and transmitted to a consuming device through the hollow guide vanes of the adjustable guide grid, as well as through the plates and journals of these blades; b. the guide vanes of the adjustable guide grid pivot only in the outer casing of the compressor or in the outer casing of the engine, according to a known construction
