Abstract

Selon l'invention, une turbine à gaz comprend un bloc réacteur comprenant un compresseur haute pression (HP), une chambre de combustion, et une turbine HP dans un agencement de flux en série. Une turbine basse pression (LP) est disposée axialement à l'arrière du bloc moteur et comprend une pluralité d'étages de pales de rotor. Un dernier étage de pales de rotor comprend un étage de pale de rotor à faible tourbillon. Un compresseur LP est positionné axialement à l'avant du bloc moteur et est accouplé à la turbine LP par une boîte de vitesses. Le compresseur LP est positionné radialement à l'extérieur en partant de la boîte de vitesses. Un ensemble ventilateur est directement accouplé au compresseur LP de telle manière que l'ensemble ventilateur et le compresseur LP tournent à la même vitesse. Un ensemble bâti-moteur comprend un élément de bâti de ventilateur avant disposé axialement entre le compresseur LP et le compresseur HP. L'ensemble bâti-moteur comprend également un élément de bâti central de turbine placé entre la turbine HP et la turbine LP.
