    • La présente invention vise, dans un encombrement axial réduit, à permettre une dilatation libre de l'enveloppe d'un couvercle de compresseur centrifuge selon la direction radiale lors des montées en température, afin de maîtriser la tenue des jeux radiaux en bord d'attaque et des jeux axiaux en bord de fuite. Pour ce faire, l'invention prévoit un couvercle (30) dans lequel la jonction (41) entre l'attache (4) et l'enveloppe (3) est formée entre sensiblement le milieu (I) de l'enveloppe (3) et son bord de fuite (B F ) et dans lequel, à froid, l'attache (4) présente essentiellement une forme concave (43) élastiquement déformable en flexion. Cette forme concave (43) est raccordée à l'enveloppe (3) par une paroi (5) se prolongeant au niveau de la jonction (41) par une forme convexe (44), de sorte que l'attache (4) présente, globalement, une configuration en coupe en forme de « S » avec une jonction (41) située plus près du bord de fuite (B F ) de l'enveloppe (3) que de son bord d'attaque (B A ).

    • An InfraRed Suppression System (IRSS) includes an exhaust manifold and a high aspect ratio exhaust duct along a longitudinal length thereof. The IRSS minimizes impingement of engine exhaust onto adjacent aircraft structure by discharging the flow upwardly and/or outwardly, away from the fuselage at relatively high velocity to reduce fuselage heating due to plume impingement in both hover and forward flight thus minimizing fuselage IR signature contributions. Furthermore, by directing the exhaust stream upward, a direct line of sight to the exhausted IR energy is masked from ground threats. The high aspect ratio exhaust duct and exhaust manifold are also preferably shrouded by an aerodynamic fairing which provides an aerodynamic contour to minimize aerodynamic impact to the aircraft and defines an air-cooled ejector gap to augment airflow to further insulate and obscure the high temperature exhaust gas exhausted through the exhaust duct.

    • The present utility model provides an exhaust device and a combustion turbine comprising the exhaust device. The exhaust device comprises: a housing (100), comprising an exhaust end cavity (110) and a closed end cavity (130); an inner diffuser (300), arranged in the housing and located between the exhaust end cavity and the closed end cavity; an outer diffuser (500), configured to surround the inner diffuser and to define a gas flow passage that guides gas to flow in an axial direction of the housing into the exhaust end cavity and the closed end cavity; and a centrifugal guide member (700), arranged at a position, corresponding to the gas flow passage of the outer diffuser, on an inner wall of the closed end cavity, such that gas is guided to flow in a direction along the inner wall of the closed end cavity when the gas flowing in a direction towards the inner wall of the closed end cavity from the gas flow passage of the outer diffuser reaches the centrifugal guide member. Therefore, gas can be guided to flow in a direction along the inner wall of the closed end cavity, and a gas flow with a uniform flow velocity can be formed in the closed end cavity.
