Abstract

Turbomoteur comprenant : - un générateur de gaz comprenant un rotor (4) qui est sensiblement vertical ; - une turbine de puissance qui entraine un arbre de transmission (7) ; - un palier (8) guidant le rotor (4) et l’arbre (7) tout en étant lubrifié avec de l’huile ; - un dispositif de récupération d’huile (10) qui est disposé directement en dessous du palier (8) et qui comprend un récipient (11) annulaire ; - un circuit d’air (12) pour pressuriser le palier (8) ; le dispositif de récupération d’huile (10) comprenant un déflecteur annulaire d’air (13) disposé axialement entre la turbine de détente et le récipient (11), le déflecteur (13) étant en regard et distant du récipient (11) de sorte à former entre eux une voie d’écoulement d’air (14) du circuit (12), la voie (14) étant alimentée par au moins un passage (15) formé dans le rotor (4) du générateur de gaz. Figure pour l'abrégé : 2A turboshaft engine comprising: - a gas generator comprising a rotor (4) which is substantially vertical; - a power turbine which drives a transmission shaft (7); - a bearing (8) guiding the rotor (4) and the shaft (7) while being lubricated with oil; - an oil recovery device (10) which is arranged directly below the bearing (8) and which comprises an annular container (11); - an air circuit (12) for pressurizing the bearing (8); the oil recovery device (10) comprising an annular air deflector (13) arranged axially between the expansion turbine and the container (11), the deflector (13) being opposite and distant from the container (11) so as to form between them an air flow path (14) of the circuit (12), the path (14) being supplied by at least one passage (15) formed in the rotor (4) of the gas generator.
