摘要： A method of controlling a turbine engine, including: measuring a first temperature by a first temperature sensor; measuring a second temperature by a second temperature sensor; estimating a third temperature modeling the first temperature; and determining at least one control setpoint for at least one piece of variable-geometry equipment of the engine, as a function of the measured first temperature. The first sensor presents a time constant longer than a time constant of the second sensor. The method further detects ingestion of water or hail as a function of a drop in the measured second temperature; and when water or hail ingestion is detected, determines the control setpoint as a function of the estimated third temperature.

摘要： A method and system for controlling clearance between the tips of blades of a turbine rotor in a gas turbine airplane engine and a turbine ring of a casing surrounding the blades. A valve is controlled to act on a flow rate and/or a temperature of air directed against the casing. The valve is of the on/off type for switching between an open state and a closed state in a determined reaction time, the valve control module including a corrector for determining a first binary control signal that can take a first value corresponding to an open state and a second value corresponding to a closed state of the valve. The corrector includes a time-delay module for determining a binary control signal, with the duration between two successive changes of state in the control signal being not less than the reaction time of the valve.

摘要： Detecting a state of icing in a turbomachine fuel circuit includes reading information representative of a first temperature T1 of the fuel downstream from the metering unit, and of comparing the first temperature T1 with a first reference temperature T01. The method also includes detecting clogging of the filter unit. In the event of the temperature reading T1 being less than the first reference temperature T01 and of clogging being detected, a signal indicative of an icing state in the fuel circuit is issued. Information representative of a second fuel temperature T2 in the tank may be read and compared with a reference temperature T02 in order to confirm or contradict the icing state. A signal indicating a need for maintenance of the fuel circuit is issued when the temperature readings T1 and T2 are not less than the reference temperatures T01 and T02 and clogging has been detected.
