摘要： A method of performing a health check of at least one turbine engine (3). During a development step (STP0), the installation losses (1) are quantified for a plurality of test values for a reduced speed of rotation (Ng′) of a gas generator (4) of the engine. During an acquisition step (STP1), the speed of rotation of said gas generator (4) is increased until said engine develops a maximum power, and then the speed of rotation of the gas generator (4) is decreased until the reduced speed of rotation (Ng′) reaches a test value. The aircraft is stabilized and at least one monitoring value is acquired. During an evaluation step (STP2) of evaluating the health check, at least one operating margin is determined by using a monitoring value and the effects of mounting the engine in an airplane.

摘要： The invention relates to a method for controlling a number of fans (2) of a heat exchanger that can be used in refrigeration, air conditioning, or process technology. The fans (2) form a number of fan groups (5), and each fan group (5) is connected to an electrical energy supply (7) selectively by means of a constant power supply (14) or by means of a variable power supply (15). The fan group (5) is operated at a constant fan speed with the constant power supply (14) and at a variable fan speed with the variable power supply (15). A power parameter (I) indicating an instantaneous total power demand of all fan groups (5) supplied by means of the variable power supply (15) is detected. At least one of the fan groups (5) that is currently being fed by means of the variable power supply (15) is switched to the constant power supply (14) if the power parameter (I) exceeds a limit value (Imax).

摘要： A method and configuration from maintaining a constant of air to a protective helmet (4) from a fan (3) in a battery powered fresh air unit. The fan (3) is a radial fan with a filter (5) positioned on the suction side of the fan and is operated by a brushless continuous current motor (2). With the aid of signals from position sensors (30) in the motor (2), a control unit (12) can determine the speed of the fan (3). The control unit also detects the motor's power consumption and compares this and the speed with a characteristic curve for the motor (2) for a given flow from the fan, which is stored in a memory (14). In the event of any deviation, the control unit (12) regulates a change of the voltage supply to the motor (2) so that the deviation is reduced.

摘要： The invention relates to a process and device for feedback-controlling the speed of an electric motor (10) driving a rotary machine (6), in particular a pump or fan, according to the capacity requirement at the rotary machine, which is variable with time on the consumer side (4, 8) thereof, using a feedback controller (16) the output of which determines the speed of the electric motor (10).

摘要： Herein provided are methods and systems for controlling an engine having a variable geometry mechanism. A pressure ratio between a first pressure at an inlet of the engine and a predetermined reference pressure is determined. An output power for the engine is determined. The output power is adjusted based at least in part on the pressure ratio to obtain a corrected output power. A position control signal for a variable geometry mechanism of the engine is generated based on the corrected output power and the pressure ratio. The position control signal is output to a controller of the engine to control the variable geometry mechanism.

摘要： An engine controller may include a processor and a feedback interface electrically coupled to the processor and one or more electric machine motor generators deployed in an aircraft engine. A memory, electrically coupled to the processor, is configured to store reference data used to indicate a presence of an icing condition. The processor is configured to monitor a feedback signal received at the feedback interface from the one or more electric machine motor generators and identify whether the feedback signal indicates that the icing condition is currently present in the aircraft engine based on a correspondence between the feedback signal and the reference data. The processor is configured to initiate an icing condition mitigation action in response to identifying that the icing condition is present.

摘要： An integrated system and methods therefore are provided. An integrated system has individual power and/or thermal systems and a coordinated control system. The coordinated control system receives mission demands and priorities from an upstream system. The coordinated control system also receives a status and a prediction from each individual system, such as an individual system's operating mode status and its capability margin. The coordinated control system performs a conflict of interest check and generates a relative status for each individual system based on the status and predictions associated with the individual systems. The coordinated control system determines an operating mode and an allowed demand for each individual system based on the relative statuses and the mission demands and priorities. The coordinated control system outputs the operating modes to the individual systems and maps the allowed demands to individual system demands. The individual system demands are output to the individual systems.

摘要： A method for providing overspeed protection for a gas turbine engine having an engine shaft includes monitoring, via an overspeed protection system, a torque of the engine shaft. The method also includes determining, via the overspeed protection system, at least one additional condition of the engine shaft. Further, the method includes determining, via the overspeed protection system, an overspeed condition of the gas turbine engine when the torque of the engine shaft drops below a torque threshold and the at least one additional condition of the engine shaft is indicative of the gas turbine engine being in an operational state. Thus, the overspeed condition is indicative of an above normal rotational speed of the engine shaft. In addition, the method includes initiating a shutdown procedure for the gas turbine engine in response to the determined overspeed condition to reduce the rotational speed of the engine shaft.
