Title (EN) LOW BLADE FREQUENCY TITANIUM COMPRESSOR WHEEL
(FR) ROUE DE COMPRESSEUR EN TITANE À BASSE FRÉQUENCE DE PALE
Abstract: front page image
(EN)A compressor wheel (20) for an air boost device and a method for designing the wheel are provided. The compressor wheel (20) comprises a hub (24) and a plurality of blades (22, 23) connected to the hub (24). The plurality of blades (22, 23) have a ratio (f/N) of natural frequency to maximum rotational speed of less than 4.0 and are made from a titanium alloy. The plurality of blades (22, 23) can comprise a plurality of full blades (22) and a plurality of splitter blades (23).
(FR)L'invention concerne une roue de compresseur (20) pour un dispositif de suralimentation d'air et un procédé pour concevoir la roue. La roue de compresseur (20) comprend un moyeu (24) et une pluralité de pales (22, 23) reliées au moyeu (24). La pluralité de pales (22, 23) a un rapport (f/N) de la fréquence naturelle à la vitesse de rotation maximale inférieur à 4,0 et est constituée à partir d'un alliage de titane. La pluralité de pales (22, 23) peut comprendre une pluralité de pales pleines (22) et une pluralité de pales de fractionnement de flux (23).
