摘要： A method for purging fuel from a fuel system of a gas turbine engine on shutdown of the engine comprises, in one aspect, terminating a fuel supply to the fuel system and using the residual compressed air to create a reversed pressure differential in the fuel system relative to a forward pressure differential of the fuel system used to maintain fuel supply for engine operation, and under the reversed pressure differential substantially purging the fuel remaining in the system therefrom to a fuel source.

摘要： In a method for operating a gas compressor which compresses gas whose supply conditions change and which is equipped with an intake-flow regulating mechanism, a limit pressure ratio that defines the operational upper limit of the pressure ratio relative to the intake flow rate of the gas compressor or the degree of opening of the intake-flow regulating mechanism to prevent surging in the gas compressor is corrected by multiplying a reference limit pressure ratio calculated from the design conditions of the gas compressor by a first correction factor calculated depending on a detected operating-state value of the gas compressor.

摘要： A passive leakage device for an axial turbomachine, more particularly for a low-pressure compressor of an axial turbomachine, is adapted to reduce and/or eliminate the surging phenomenon within the machine. The passive leakage device includes an insert having a general cylindrical shape with a flange at one end and a bottom or membrane at the other end. The membrane comprises two cross-shaped notches, the notches being adapted to enable a deformation of the membrane under a pressure exceeding a predetermined threshold, so as to allow a leakage to go through the membrane. Several inserts are arranged through the wall of a compressor casing, distributed over one or several circumferences of the casing, facing one or several rows of rotor blades. In the case of a double-flow turbomachine, such as a jet engine, the beak for separating the primary and secondary flows is used to form a chamber for communication between the inserts and for compensation with the pressure present in the secondary flow.

摘要： A turbomachine includes a turbine portion having a housing enclosing one or more turbine stages. Each of the one or more turbine stages includes a plurality of turbine buckets. The plurality of turbine buckets include an upstream portion and a downstream portion. A first sensor is mounted in the turbine portion at the upstream portion of plurality of turbine buckets and a second sensor is mounted in the turbine portion at the downstream portion of the plurality of turbine buckets. A controller is operatively coupled to the first and second sensors. The controller is configured and disposed to detect a change in flow between the upstream portion and the downstream portion and signal an alarm if the change in flow falls below a predetermined threshold value.

摘要： A system controls net thrust of a steam turbine having a stepped rotating shaft. A first leak off line fluidly couples a first stage of a turbine section to a packing upstream of a stepped portion on the rotating shaft. A second leak off line fluidly couples a second stage of the turbine section that is subsequent to the first stage to a step area upstream of the stepped portion, and a connection line fluidly couples the first leak off line to the second leak off line. The lines include control valves such that a controller can actively control the net thrust by regulating thrust pressure on the stepped portion using steam from the first and second stages of the turbine section. The controller may also prevent damage to an active retractable seal using the control valves.

摘要： A closed-loop system includes a pump driving a fluid through a series of conduits. A control system is included that minimizes pressure fluctuations in a bootstrap reservoir to maintain a desired minimum pressure at the pump inlet. Moreover, the control system reduces a maximum system pressure by reducing the magnitude of pressure fluctuations encountered by the bootstrap reservoir.
