摘要： The present invention describes a gas turbine having two shafts, which are rotatably mounted using bearing devices in the area of a casing. An intermediate shaft sealing device is arranged between the bearing devices, which includes a sealing element connected to a first shaft, in which a further sealing element connected to the second shaft radially engages. An operating pressure is applied, in the area limited by the shafts in the axial direction of the shafts, to facing effective areas of the sealing elements, while the pressure prevailing in the area outside the shafts in the axial direction acts on effective areas of the sealing elements facing away from one another. A ratio between the outer diameters limiting the facing effective areas and the inner diameters likewise limiting these effective areas is in each case greater than or equal to 1.25.

摘要： The speed of a high-pressure turbine of a gas turbine engine may be determined using known centrifugal pump affinity relationships for a fuel pressure apparatus, fuel pressure apparatus input and output pressures, and gear ratios for a mechanical linkage between the high-pressure turbine and the fuel pressure apparatus. The technique avoids wear-related variations in gas pressure based measurements and also applies to fuel pressure apparatus using both single pump and multiple pump configurations.

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.
