    摘要: A high bypass ratio turbojet engine comprising a fan rotated by the shaft of a low pressure turbine via a speed reducer is provided with a thrust reverser device by providing the speed reducer with first and second epicyclic gear trains which are mounted in parallel between the low pressure turbine and the fan and which are arranged in such a way as to drive the fan in a first direction of rotation when the engine is operated in a direct thrust mode, and to drive the fan in the opposite direction of rotation when the engine is to be operated in the reverse thrust mode.

    摘要: A deburring machine essentially comprising a cutting tool (13) which pivots on an axis (16) that is perpendicular to the axis of rotation (X) and which may be retracted inside the cover (11) by a wedge (10) so that the cover (11) may be inserted through a hole; the cutting tool (13) may then be extended and opened out to deburr the edge of the hole situated on the hidden face of the part. The cutting tool pivots freely in order to adopt the correct angle for the edge to be deburred.

    摘要: A redundant front suspension system for a turboshaft engine mounted on a pylon of an aircraft comprises a primary suspension device forming the normal front suspension of the engine, and an emergency suspension device. The primary suspension device comprises a base member secured to the pylon and having a suspension shaft which co-operates with the intermediate casing of the engine, and thrust take-up rods connect the intermediate casing to the base member. The emergency suspension device comprises an additional member which is interposed between the pylon and the base member of the primary device and which has a second shaft at its forward end extending parallel to the longitudinal axis X of the engine, the second shaft being received with clearance in a bore provided in the intermediate casing and being equipped with means for enabling take-up of forces along the X, Y and Z axes in the event of failure of an element of the primary suspension device.

    摘要: Device for cooling the external part of a turbine disk (2) by means of an external fresh air current (circuit II) without mixing with the warmer ventilation from the center of the disk (circuit I). A part (30) through which ducts (31, 32) pass that intersect without interruption, prevents mixing of substantially perpendicular streams in front of a part (22) of the disk (2) and a mixture which reduces the cooling efficiency.
