A terminal block of a gas turbine engine includes: at least one electric conductor on and with which terminals of electric wires of electric parts and an electric device are laminated in a first direction and are in contact; at least two insulators laminated so as to sandwich the terminals and the electric conductor in the first direction; a stopper opposed to a first-end insulator located at a first end side in the first direction among the at least two insulators; and a spring arranged between the stopper and a second-end insulator located at a second end side in the first direction among the at least two insulators, the spring pressing the terminals against the electric conductor in the first direction.

Layers of conductors and insulators forming a terminal block

In a flange cooling structure of a gas turbine engine, one of a first flange and a second flange is a high pressure flange that faces a first region, and the other of the first flange and the second flange is a low pressure flange that faces a second region. A contact surface of the high pressure flange or a contact surface of the low pressure flange includes a cooling groove that communicates with the first region and the second region.

Flange cooling structure for gas turbine engine

A gas turbine engine including a compressor that compresses air taken in; a combustor that sprays a fuel into the compressed air and combusts the fuel; a turbine rotated by energy of the combustion gas generated by the combustor; a rotating shaft coupling the compressor and the turbine; a rear bearing that is a cageless ball bearing including an inner race, an outer race, and a ball, the inner race being fixed to a portion of the rotating shaft which portion is close to the turbine; a housing to which the rear bearing is attached; and a rear bearing holding member that is interposed between the rear bearing and the housing and holds the outer race of the rear bearing such that the outer race of the rear bearing is movable in an axial direction relative to the housing.

Gas turbine engine

A gas turbine engine includes: a fan that is in front of a compressor and rotates in association with a rotating shaft; a casing including an inner shell and an outer shell and a bypass passage; bearings inside the inner shell; an oil mist generator that is outside the outer shell and generates oil mist by mixing oil with compressed air extracted through an extraction port of the compressor; an air pipe through which the compressed air extracted from the compressor is guided to the oil mist generator; and an oil mist pipe through which the oil mist generated by the oil mist generator is guided to the bearings. At least one of the air pipe and the oil mist pipe includes a heat exchanger that is in the bypass passage and is cooled by the air flowing through the bypass passage.
