Abstract: 1358076 Gas turbine ducted fan engines ROLLS-ROYCE (1971) Ltd 19 June 1972 [19 June 1971] 28892/71 Heading F1J The invention relates to a gas turbine ducted fan engine and to an arrangement of annular or part-annular oil manifolds and oil cooler elements. The engine shown comprises a core engine 1 which is arranged to drive a ducted fan 2, the core engine comprising an outer casing 5 within which is mounted an annular oil tank 7, the tank being associated with a plurality of oil cooler elements 10 which project radially into the fan duct. The tank 7 is associated with a pair of manifolds 14, 15 and the manifolds are inter-connected by the plurality of oil cooler elements 10, each element being in the form of a hollow vane in which is disposed an inner member 17 so as to form a narrow oil flow passage; the vane is provided with cooling fins 30. Hot oil and air passes into the manifold 14 and discharges through opening 12 into the hollow vane 10 where it is cooled by the fan air flow. The oil and air discharges from the vane through opening 13 into the manifold 15 and thence through a spray bar 16 from which the oil and air mixture is discharged on to an arcuate plate 20 which is formed with radially outwardly plunged holes 21. The oil passes across the plate and is collected in the tank while the air passes through the holes 21 and is vented to atmosphere. The cooled oil is re-circulated.
