OIL AND FUEL CIRCUITS IN A TURBOMACHINE AND METHOD FOR MANAGING HEAT EXCHANGES

摘要

Oil and fuel circuits in a turbomachine, comprising a main oil/fuel heat exchanger (36) through which flows of oil and of fuel flow in order to cool the oil, and an oil/air heat exchanger (54) mounted in the oil circuit (68) and through which a flow of cooling air flows, a bypass pipe (62) mounted between the oil inlet and outlet of the oil/air heat exchanger (54) and a valve (64) controlling the passage of the flow of oil through the bypass pipe (62) and through the oil/air heat exchanger (54), characterized in that a secondary oil/fuel heat exchanger (60) is mounted in the bypass pipe (62).
