摘要： A radial centrifugal turbomachine with an adjusting device operatively active at the axial inlet of the turbomachine fixed casing, including: an annular member delimiting at least one radially inner passage at the axial inlet, wherein the member front surface and abutment surface of the casing delimit a radial annular passage. An actuator is connected to the member and to move axially and/or rotate according to a predefined angle to vary the radial annular passage and/or passage sections delimited between stator blades of the turbomachine first radial stage. A transmission shaft coaxial with the rotation axis and integral with the member is operatively connected to the actuator. The adjusting device allows adjusting the mass flow rate at the inlet to better adapt the performances of the turbomachine to the loading of the process/cycle and to implement a safety system dedicated to stopping the turbomachine in case of an urgent stop request.

摘要： A variable area fan nozzles comprising an array of rigid petals hinged to a lip area at the downstream end of a thrust reverser sleeve (or half-sleeve). In one embodiment, the actuation system comprises a rotatable ring segment, a drive system for rotating the ring segment, a plurality of cams attached or integrally formed with the ring segment, a plurality of cam followers, and a plurality of petal linkages which operatively couple the petals to the cam followers. This actuation system controls the deflection of the petals, thereby controlling the amount of opening and the rate at which the fan nozzle throat area changes. Each cam may have forward- and rearward-facing camming surfaces that interact with the cam followers to force the petals to pivot outward or inward respectively.

摘要： The divergent segment comprises a stationary divergent portion and a movable divergent portion suitable for occupying a retracted position and a deployed position. The threaded rod has a head suitable for being supported by a support secured to the stationary divergent portion in cooperation with rotary drive means for driving the threaded rod in rotation, and a tip suitable for being inserted in a holder sleeve secured to the stationary divergent portion. The threaded rod is suitable for co-operating with a nut secured to the movable divergent portion so that rotation of said rod causes the movable divergent portion to move. The tip presents an enlargement having at least one groove passing axially therethrough.

摘要： A method of assembling a heat exchanger in a gas turbine engine assembly is provided. The method includes providing a structural body including a wall having an elongated slot, providing a heat exchanger operably associated with a bracket, and providing a slip joint for coupling the bracket to the structural body. The slip joint includes a standoff, an elongated member, and a biasing member disposed about the elongated member. The standoff is inserted through the wall so that the biasing member imparts a predetermined biasing force between the bracket and the structural body. The slip joint allows relative sliding movement between the bracket and the structural body when a sliding force due to thermal expansion or contraction is greater than the biasing force.

摘要： This trailing edge is of the type with moving chevrons (9a, 9b, 9c). It comprises actuating means able to cause these chevrons (9a, 9b, 9c) to move from a passive position in which they are directed substantially in the direction of the airflow leaving the said engine, into an active position in which at least part of each chevron is inclined with respect to this direction. This trailing edge is notable in that the said active position is derived from the said passive position by pivoting, possibly combined with a translational movement, of at least part of each chevron about an axis (Aa, Ab, Ac) substantially parallel to the said direction.

摘要： The guide blades provided for the variable turbine geometry are adjustably arranged within a radial gap through which gases can flow on a moveable carrier ring, which is axially clamped against stops on or in the radial gap with a thrust spring device. According to the invention, the thrust spring device loads the carrier ring on the positions closely adjacent to the stops. The thrust spring device is designed open without sealing function and if applicable combined with a separate seal without thrust function.
