IMPROVED TURBINE AND BLADE FOR THE PROTECTION OF THE ROOT FROM FLOW PATH HOT GASES

A urbine (14), and particularly a low pressure turbine is disclosed, which comprises a plurality of rotor members (2) and spacers for arranged between rotor members, to avoid that an ingested gas flow from the hot gas flow path channel (F) reaches the wheel space (5). The rotor members each include...

Summary:A urbine (14), and particularly a low pressure turbine is disclosed, which comprises a plurality of rotor members (2) and spacers for arranged between rotor members, to avoid that an ingested gas flow from the hot gas flow path channel (F) reaches the wheel space (5). The rotor members each include a deflector (8). The deflector is placed in correspondence with each spacer and deflects the ingested gas flow over the upper surface of the spacer, thus preventing it to heat up the roots of the blades (4). L'invention concerne une turbine (14), et en particulier une turbine basse pression, qui comprend une pluralité d'éléments de rotor (2) et des éléments d'espacement destinés à être disposés entre des éléments de rotor, afin d'éviter qu'un écoulement de gaz ingéré à partir du canal de circuit d'écoulement de gaz chaud (F) n'atteigne l'espace pour roue (5). Les éléments de rotor comprennent chacun un déflecteur (8). Le déflecteur est placé en correspondance avec chaque élément d'espacement et dévie le flux de gaz ingéré sur la surface supérieure de l'élément d'espacement, ce qui l'empêche de chauffer les pieds des pales (4).
