Temperature control system for lubricant and fuel of a jet engine

摘要

The system provides temperature control of oil and fuel in the turbojet engine (1) equipped with an alternator (2). It includes a first oil circuit (4) for cooling the engine oil, and a second oil circuit (10) for cooling the lubrication oil for the alternator. The first oil circuit (4) includes an air/oil heat exchanger (5) and a fuel/oil heat exchanger (7) as well as an oil/oil heat exchanger for the cooling the oil circulating in the second oil circuit (10). Controls (20-25) are provided for the flow of oil through the exchangers as a function of the flight conditions and the oil temperatures.
