Abstract
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.
