    摘要： An engine bleed air system (60) for providing air to an aircraft system includes a port (62) for extracting bleed air from a compressor section of an engine. The system additionally includes a turbo-generator (64) having a turbine (82) and a generator (84). The generator (84) is driven by rotation of the turbine (82). A boost compressor (66) is fluidly coupled to the port (62). Bleed air from the port (62) is selectively provided to one of the turbo-generator (64) and the boost compressor (66) based on a demand of the aircraft system.

    摘要： It is known that power is normally extracted within a gas turbine engine from a shaft in order to drive auxiliary devices such as electrical power generators. With high extraction rates from such shafts there is mismatching in rotational speeds between the shafts which must be adjusted through leakage taken from valves (8,9). By measuring parameters and in particular pressure at a number of positions or parts within an engine arrangement (1) and comparing those parameters either through ratios or directly with reference values a controller can be configured in order to choose the correct sequence and scheduling of the valves (8,9) opening to balance shaft speed. In such circumstances more efficient operation of the engine arrangement can be achieved over a wider range of engine speeds including idling.

    摘要： A control lever having one end adapted for attachment to a resting device for controlling movement thereof, and another end having a tactile contour for identifying the control lever. A preferred embodiment is defined by a chair (41) having a selectively moveable back (43) and seat (45) including first and second lever control arms (52, 54), each arm having one end attached below the seat, and another end presenting a tactile shape (53, 55). The shapes of the first and second lever control arms are different from one another. The chair also includes a guide (65) presented by an arm of the chair for displaying the indicia representative of the different shapes and the associated movements of the first and second lever control arms.

    摘要： A method of controlling a gas turbine engine (10) which has a booster compressor (13), a core compressor, combustion equipment, a core turbine, and a low-pressure turbine (18). The low-pressure turbine also drives an external load having a defined speed characteristic. The booster compressor (13) has one or more rows of variable stator vanes. The method includes: scheduling variation in the angle of the variable stator vanes as a function of the speed of the booster compressor such that the vanes open as the booster compressor speed increases; measuring or setting one or more operational parameters which are determinative of the temperature at entry to the core turbine; and biasing the scheduling of the angle variation of the variable stator vanes as a function of the operational parameter(s) to reduce variation in temperature at entry to the core turbine

    摘要： A coupling system (20) includes a dynamoelectric device (22) selectively operable as either a generator or an electric motor, a gas turbine engine (24), a main differential (26) operably connected between the dynamoelectric device (22) and the gas turbine engine (24), a rotationally powered accessory (34) engaged with the main differential (26), an epicyclic start differential (28) operatively connected to the main differential (26), and a brake mechanism (36). The brake mechanism (36) is configured for selectively braking the epicyclic start differential (28) when the dynamoelectric device (22) operates as an electric motor to direct torque transmission to the gas turbine engine (24), and is further configured to cease braking the epicyclic start differential (28) when the dynamoelectric device (22) operates as a generator such that the main differential (26) transmits torque to power the rotationally powered accessory (34) and to the dynamoelectric device (22)
