A method for estimating the temperature of the fuel entering a turbomachine injector, the turbomachine including engine spaces and an oil/fuel exchanger upstream of the injector, the engine spaces and the oil/fuel exchanger having oil passing through them, the oil/fuel exchanger having an efficiency, the engine spaces including a high-pressure spool, the method including (a) measuring the temperature of the oil entering the engine spaces; (b) measuring the rotational speed of the high-pressure spool; (c) calculating the temperature of the fuel leaving the oil/fuel exchanger using the temperature of the oil entering the engine spaces and the rotational speed of the high-pressure spool.

Method of estimating the temperature of the fuel leaving a turbomachine exchanger

A device includes a first hot fuel bleed, a second cold fuel bleed, a fuel pressure regulator including a fuel inlet line, a fuel outlet line and a fuel pressure set point line, the pressure of the outlet line being set by the regulator to a fixed divergence from the pressure of the set point line, a first connector to connect the first bleed to the inlet line of the regulator and the second bleed to the set point line of the regulator, when a first pressure of the first bleed is greater than or equal to a second pressure of the second bleed and to connect the first bleed to the set point line of the regulator and the second bleed to the inlet line of the regulator when the first pressure is lower than the second pressure, and a second connector.
