    摘要: A system (7) for cooling a transmission (6) of a hover-capable aircraft (1), the system having : a stator (3); a heat exchanger (8) connectable thermally to the transmission (6); a fan (9) for creating a current (P) of a first heat-carrying fluid from the heat exchanger (8) to the fan (9) itself, to remove heat from the heat exchanger (8); a rotary member (10), which rotates about an axis (A) to rotate an impeller (20a) of the fan (9) about the axis (A); and a bearing (16) supporting the rotary member (10) for rotation about the axis (A);
    the system (7) also having cooling means for cooling the bearing (16), and in turn having conducting means (40; 42, 41, 30, 29) for conducting a current (Q) of a second heat-carrying fluid along a path from an outside environment (50), external to the bearing (16), to and to cool the bearing (16) itself.
