    摘要： A method to detect shaft break that comprises monitoring first and second parameters and defining a two-dimensional parameter space that is a function of the first and second parameters, the two-dimensional parameter space comprises integration regions. The method also comprises defining an integration function for each integration region. For measured values of the first and second parameters, the method determines the applicable integration region and applies the integration function to the first parameter to give an integration result; and then sets a shaft break signal to TRUE when the integration result exceeds a predetermined threshold. The present invention also provides a shaft break detection system.

    摘要： A turbine fuel supply system is disclosed as including a first sub-system having: a first nozzle for injecting fuel into a combustor of a turbine engine; a first valve controllable to communicate fuel to the first nozzle; and a first fuel manifold for communicating fuel to the first valve from a fuel source; the system further including a controller assembly for raising the pressure of fuel in the first fuel manifold; and the system being characterized in that the first valve is adapted to open in response to a predetermined pressure difference between the first fuel manifold and the pressure in the combustor, thereby allowing fuel to be communicated from the first fuel manifold to the first nozzle. The system may include a first recirculating conduit in fluid communication with the first fuel manifold and the fuel source, the first recirculating conduit allowing fuel not communicated by the first valve to be returned to the fuel source.

    摘要： It is known that overshoot in fuel flow rate as a result of compensating for engine heat soak effects can create transient over values in desired thrust parameters. By adjusting the normally calculated fuel flow rate to a fuel regulator (22) by the introduction of a fuel flow adjustment dependent upon a variable which is related to heat soak effects it is possible to reduce the extent of overshoot as well as the transient time period of that overshoot to ongoing operational state. The variable used may be direct or indirect and will generally utilise a temperature sensor (25) within the engine and/or other engine control procedures which may be extrapolated from such sensor values to provide a variable for heat soak compensation.

    摘要： A ducted fan gas turbine engine (10) is provided with a plurality of sensors (23) which detect the presence of liquid water in air exhausted from the high pressure compressor (14) of the engine into its combustion system (15). In the event that liquid water is detected, the fuel flow to the combustion system (15) is increased to cause the high pressure compressor (14) to rotate faster and thereby vaporize the liquid water. Such liquid water can be present in the air exhausted from the high pressure compressor (14) when the engine (10) is operating in very heavy rain and can adversely affect normal engine operation.

    摘要： A compressor (32) variable stator vane arrangement comprises at least one stage of variable stator vanes (42). A speed sensor (50) measures the rotational speed (N2) of the compressor rotor (36). A pressure sensor (54) measures the outlet pressure (PS26) of the compressor (32). A second pressure sensor (47), a temperature sensor (51) and a third pressure sensor (55) measure the total inlet pressure (P20), the temperature (T20) and the ambient pressure (Pamb) at the inlet of the gas turbine engine (10). A processor (58) determines a target operating line as a function of ambient pressure (Pamb) and total inlet pressure (P20). The target operating line is defined to ensure the gas turbine engine (10) operates simultaneously at both the minimum required compressor speed and the minimum required compressor outlet pressure when commanded to idle to minimise idle thrust and fuel burn. The processor (58) determines if the operating point of the compressor, defined in terms of corrected outlet pressure (PS26/DP20) and corrected rotational speed (N2RTHT20) of the compressor rotor (36) is above or below the target operating line of the compressor (32). The processor (58) adjusts the angle of the variable stator vanes (42) to make the operating point operate on the target operating line.
