摘要 |
The invention relates to a method for estimating the temperature of the fuel entering a turbomachine injector, the turbomachine comprising engine spaces (8) and an oil/fuel exchanger (3) upstream of the injector (7), the engine spaces (8) and the oil/fuel exchanger (3) having oil passing through them, the oil/fuel exchanger (3) having an efficiency (Eff MHX), the engine spaces (8) comprising a high-pressure spool, the method comprising the following steps: - (a) a step (101) of measuring the temperature of the oil entering the engine spaces (Toil engine inlet); - (b) a step (102) of measuring the rotational speed of the high-pressure spool (XN25); - (c) a step (103) of calculating the temperature of the fuel leaving the oil/fuel exchanger (Tfuel MHX outlet) using the temperature of the oil entering the engine spaces (Toil engine inlet) and the rotational speed of the high-pressure spool (XN25). |
