AIRCRAFT ENGINE WITH ELECTRIC STARTER COOLING Russian patent published in 2014 - IPC F02C7/268 F02C7/14 F02C7/236 

FIELD: transport.

SUBSTANCE: invention relates to an aircraft engine including a fuel-pump device. The fuel-pump device contains a high-pressure fuel pump (26) having an inlet connected to the low-pressure fuel pipe (28) and an outlet connected to the main high-pressure fuel supply circuit. The engine includes an electric device (40) for the engine starting and a cooling device for an electric starter connected to the pumping device for fuel cooling by means of circulation. The cooling device (54, 56, 58) is supplied with fuel using a pump (50) having an inlet connected to the pumping device upstream the high-pressure pump (26) and which is actuated using an electric motor (52) independent of the high-pressure pump (26).

EFFECT: sufficient flow rate of the cooling fuel at low speed without oversized discharge of the high-pressure pump which results in less bulkiness and less complexity of implementation than adding of a pump actuated mechanically using the engine.
