    摘要： The subject invention is directed to a new and useful method of detecting in-range engine sensor faults for a gas turbine engine associated with a helicopter. The method includes the steps of computing engine shaft horsepower for a plurality of engine sensor, computing a first mean horsepower from the plurality of engine sensors, computing the horsepower deviation from the first mean horsepower for each engine sensor, computing a horsepower deviation ratio for each engine sensor relative to all other engine sensors, disabling the engine sensor with the largest deviation from the first mean horsepower, computing a second mean horsepower, computing the horsepower deviation from the second mean horsepower for each engine sensor, re-computing the horsepower deviation ratio for each engine sensor relative to all other engine sensors, comparing the horsepower deviation ratios to predefined limits, and declaring a sensor fault if the horsepower deviation ratio for an engine sensor exceeds a predefined limit.

    摘要： A controller (18) is provided in which an independent protection controller (38) is provided in a casing (8), which casing (8) is disposed within the casing (4) for the main controller (18), such that the protection controller (38) is provided as a box within a box. This allows the casing (4) for the main controller to provide extra protection to the protection controller (38) against mechanical stress and damage. The independent protection module is directly connected to a pilot operated "shut down" demand and in response to such a demand assumes authority to shut the engine down.

    摘要： The invention relates to a method of recognition of a shaft rupture in a turbo-engine with the purpose of initiating a suitable speed range limiting measure, especially an emergency shut-down of the fuel supply in a gas turbine system of an aircraft. According to the inventive method, a torque-supplying turbine rotor and a torque-absorbing unit are linked with one another via the shaft (3) which is to be monitored for a rupture and the ends of which are arranged on at least two roller bearings (6, 7). The rotary frequencies (fn1, fn2) of the two ends of the shaft in the roller bearings (6, 7) of the shaft (3) are detected and compared continuously and substantially in real time. If the rotary frequency (fn1) at the roller bearing (7) at the turbine rotor's end is higher than the rotary frequency (fn2) at the roller bearing (6) of the torque-absorbing unit, rupture of the shaft (3) is assumed. Preferably, the rotary frequency of the respective end of the shaft is determined via fast-Fourier transmission and an arithmetic processor for both roller bearings (6, 7) via separate measuring channels. The measurement is based on one or several typical roller bearing frequencies that are emitted by said roller bearings when they rotate.

    摘要： Le système comporte au moins un dispositif de détection de concentration critique d'eau dans la turbomachine et un dispositif permettant l'augmentation automatique du régime de rotation de la turbomachine.
    Le dispositif de détection est basé sur la mesure de l'élévation de la température de l'air au passage du compresseur et sur la comparaison de cette élévation de température à celle qui est considérée comme critique pour le fonctionnement de la turbomachine pour une vitesse de rotation donnée. Lorsque l'élévation de température mesurée est inférieure à l'élévation de température critique, le dispositif de détection envoie un signal au dispositif d'élévation du régime de rotation de la turbomachine, ce dernier comprenant un circuit à prépondérance maximum, intégré dans la boucle de régulation de la vitesse de rotation du moteur.
    La valeur la plus importante pour l'élévation du régime moteur, sera prise en compte par le circuit à prépondérance maximum qui délivrera au doseur de carburant l'information correspondante.

    摘要： A fuel control apparatus for a gas turbine engine, in which operational fuel is supplied to the engine through a primary metering valve responsive to movement of a power lever within a normal operational range, and a secondary, normally closed metering valve which is responsive to movement of said power lever within an emergency operational range in the event of a malfunction in the operation of the primary metering valve (electrical power failure, for instance).
    The invention provides for automatic detection of a possible malfunction by a sensor (402) and automatic transfer of the fuel flow requirement from the primary metering valve (56) to the secondary metering valve (62) without moving the power lever (36) when the fuel flow requirement is below a predetermined level.
    For use particularly in the control of aircraft turbine engines.

    摘要： A gas turbine engine control system comprising a variable stator vane schedule for normal operation of the gas turbine engine. The system is configured to generate an arm signal indicating potential shaft break. Then the system is configured to alter the variable stator vane schedule to slew each variable stator vane to decrease the available surge margin in response to the arm signal. Or the system is configured to limit a response rate of a variable stator vane actuator in response to the arm signal. Or the system is configured to alter the variable stator vane schedule and limit the response rate of the actuator.
