FIELD: mechanical engineering; turbojet engines.
SUBSTANCE: proposed turbojet engine includes shaft, fan mounted on one end of shaft and also first and second bearings. Shaft rests on first bearing behind the fan and on second bearing behind the first one. First bearing is held by casing enclosing the shaft and passing rearwards from first bearing to stator. Housing is fastened to stator structure by screws which pass parallel to shaft and which can be sheared off at traction force. Second bearing contains outer race it is arranged with radial clearance in hole of ring support attached to stator structure and is fasted to ring support by screws. Said screws are parallel to shaft and can be sheared off, and second bearing can rest on support in case of breakage of screws. Means are provided to prevent rotation of outer race when second bearing is disconnected.
EFFECT: reduced danger of damage to structural members caused by vibrations arising in case failure of fan.
