Abstract: A heat management system includes a fuel tank storing a fuel; a first heat exchanger thermally coupled to the fuel tank; a hydraulic pump for circulating a hydraulic fluid; a hydraulic circuit including first and second hydraulic lines fluidly coupled to the first heat exchanger and the hydraulic pump, such that the first heat exchanger brings the hydraulic fluid and the fuel into a heat exchange relationship; an oil circuit; and a second heat exchanger thermally coupled to the oil circuit and at least one of the first and second hydraulic lines, such that the second heat exchanger brings the hydraulic fluid and the oil into a heat exchange relationship, thereby allowing heat transfer between the fuel and the oil via the hydraulic fluid.

Abstract: An oil tank system (100) for a gas turbine engine is provided. The oil tank system (100) includes an oil tank (102) having an upper tank portion (112) and a lower tank portion (114), a waisted section (118) being provided between the upper tank portion (112) and the lower tank portion (114). Oil is received by a de-aerator (104) of the system (100) which supplies de-aerated oil to the upper tank portion (112). The waisted section (118) includes an upper face (119) configured to catch oil drips from above the waisted section (118) and to guide oil to a lower face (121) of the waisted section (118).
