    摘要: A method and apparatus for controlling operation of an engine (226) in an aircraft (202). A time (244) when a cutoff speed (246) for the aircraft (202) will be reached at which a flow of fuel (224) is to be stopped is identified. A delay (248) between sending a command (250) to move a switch (214) to an off position (222) and the time (244) at which the engine (226) ceases operation is also identified. The command (250) is sent based on the predicted time (244) and the delay (248). The command (250) causes the switch (214) to move to the off position (222) moving a fuel control switch (238) for the engine (226) of the aircraft (202) to a shut off position (242) to stop the flow of fuel (224) to the engine (226).

    摘要: A jet engine has an inlet which takes in air, a combustor (12) which combusts fuel by using the air, and a fuel control section (37) which controls supply of the fuel. The combustor (12) has a fuel supplying section (22) which supplies the fuel, injectors (20) which inject the fuel. Each injector (20) contains openings (30-1 to 30-5) which inject the fuel. The fuel supplying section (22) supplies the fuel to the injector (20) in a flow rate according to a command of an autopilot. The fuel control section (37) controls the injectors (20) such that the number of the openings (30) which inject the fuel or flow-path cross-section areas of the pipes which send the fuel in case of the low-speed is more than the number of the openings (30) which inject the fuel or the flow-path cross-section areas of the pipes which send the fuel in case of the high-speed.

    摘要: Methods (200) for controlling fuel mixing are provided. One or more parameters associated with the operation of a machine configured to receive a combined fuel is identified. A fuel flow of the combined fuel that is provided to the machine may be determined. Based at least in part on the identified parameters, a ratio of a first fuel type (105) included in the combined fuel to the determined fuel flow may be determined. The first fuel type may have a heating value that is greater than a second fuel type (110) included in the combined fuel. A flow of the first fuel type may be set based at least in part on the ratio. Subsequent to setting the flow of the first fuel type, an energy content of the fuel flow of the combined fuel may be determined, and the flow of the first fuel type may be adjusted based at least in part on the determined energy content.

    摘要: The present invention provides a method of operating an aircraft whereby actual acceleration of an aircraft is used as the direct measure of the capability of the aircraft to takeoff. Thus, a minimum takeoff acceleration is determined for an aircraft and then through appropriate sensing means for acceleration, actual acceleration of the aircraft is determined and compared with that predetermined minimum takeoff acceleration. If the actual aircraft acceleration exceeds the minimum takeoff acceleration then an indication such as a buzzer or signal is provided. The present method may also be used in cooperation with existing takeoff determining systems utilising engine thrust as the means of determining aircraft capability to takeoff. The authority of the various aircraft takeoff criteria can be adjusted as required. Furthermore, the present aircraft acceleration regime may be utilised with regard to adjusting existing engine thrust means for determining takeoff or cruise capability.
