Definitions
- the present invention relates to an air discharge tube support loaded with oil of a turbomachine.
- a turbomachine such as a turbojet engine or a turboprop engine, conventionally comprises, from upstream to downstream in the direction of flow of the gases, a fan, a low pressure compressor, a high pressure compressor, a combustion chamber, a high turbine pressure, a low pressure turbine, and a gas exhaust nozzle.
- Each compressor stage has a turbine stage, both of which are connected by a shaft so as to form a body, in particular a low pressure body and a high pressure body.
- the low pressure body shaft may be hollow and contain a tube, commonly referred to as "Center Vent Tube” or “CVT”.
- This tube comprises an upstream portion rotatable, extended by a fixed downstream portion and allows the discharge of oil-laden air from certain enclosures of the turbomachine.
- the downstream portion of this tube passes through an ejection cone to which it is connected by a support comprising an inner annular portion of general Omega section, surrounding the tube, and a conical portion fixed to the ejection cone and to the inner annular portion. .
- the conical portion has holes for passing a flow of cooling air through the ejection cone.
- the conical portion of the support is attached to the inner annular portion by means of screws.
- Such a carrier has the following disadvantages.
- the support zone of the tube on the support is axially offset from the support of the support zone on the ejection cone, which greatly reduces the rigidity of the support. This rigidity is further reduced by the presence of holes allowing passage of the cooling air flow.
- the ejection cone is subjected to temperatures between 650 ° C and 680 ° C, while the tube may be at a temperature between 450 ° C and 480 ° C. This large temperature difference (240 ° C) generates thermal expansion phenomena, stresses and displacements that the support must be able to absorb while retaining its qualities of rigidity.
- the current support is relatively heavy, which increases the total mass of the turbomachine, in addition to being expensive.
- the invention aims in particular to provide a simple, effective and economical solution to this problem.
- a support intended to carry a tube of air discharge loaded with oil of a turbomachine, comprising a radially inner annular part, intended to be mounted around said tube, characterized in that it comprises fins extending outwardly and in a radial plane from the annular portion at an angle to the radial direction, the fins having attachment areas at their outer periphery, said attachment areas being inclined in the axial direction of the support so as to be attached to an ejection cone of the turbomachine.
- the support zone of the tube on the support is located axially in line with the zone of attachment of the support on the ejection cone, which allows the support to have good rigidity.
- the fact that the fins are inclined relative to the radial direction further allows to adequately withstand the effects of thermal expansion that may occur in operation.
- such a support is relatively light, allows the passage of cooling air in the ejection cone, and is inexpensive. As a comparison, such a medium is about ten times lighter than the current medium.
- each fin may comprise a median zone having a first end connected to an internal fixing zone, intended to be fixed to the inner annular part of the support, and a second end connected to the external fixation zone, intended to be fixed. at the ejection cone, the median zone extending in a plane forming a non-straight angle with respect to the tangent to the annular portion passing through the first end.
- Such a feature allows the carrier to well handle the effects of thermal expansion.
- Each median zone may extend in a plane parallel to the axis of the inner annular portion.
- the median zones thus offer little resistance to the flow of air passing through the ejection cone.
- each internal fixing zone has a shape complementary to that of the inner annular portion.
- the inner zones of the fins may be fixed by brazing for example to the inner annular zone.
- the fins and the inner annular portion are made of Nickel-based superalloy, for example INCONEL 625 or INCONEL 718.
- the length of the inner annular portion is less than or equal to 0.4 times its internal diameter.
- the inner annular portion is a short guide forming, to a certain extent, a ball joint connection between the tube and the support.
- the number of fins can be between 3 and
- the invention also relates to an assembly for a turbomachine, comprising an oil-filled air discharge tube, said tube comprising an upstream portion rotatable and a fixed downstream portion, said downstream portion passing through an ejection cone and extending along the axis of said ejection cone, said downstream part being surrounded by the inner annular part of a support of the aforementioned type, so that said downstream part is mounted axially free in rotation and in translation in said inner annular part, the zones of inclined fixing of the support being further fixed to the ejection cone.
- the invention finally relates to a turbomachine, characterized in that it comprises an assembly described above.

- the conical portion 7 has holes 8 allowing the passage of a flow of cooling air passing through the ejection cone 1.
- the conical portion 7 of the support 5 is fixed to the inner annular portion 6 by means of screws, not shown.
- the support zone 9 of the tube 4 on such a support 5 is axially offset from the attachment zone 10 of the support 5 on the ejection cone 1, which greatly reduces the rigidity of the support 5. This rigidity is further reduced by the presence of holes 8 allowing the passage of cooling air flow. Moreover, such a support 5 is relatively heavy, which increases the total mass of the turbomachine, in addition to being expensive.
- the invention proposes to connect the downstream part 4a of the tube 4 to the ejection cone 1 by the support 5 illustrated in FIGS. 4 to 8.
- This support 5 comprises a cylindrical annular portion 6 radially internal, intended to to be mounted around said tube 4, and fins 1 1 extending outwardly and in a radial plane from the annular portion 6, forming an angle ⁇ with the radial direction.
- the number of fins 1 1 is for example between 3 and 10.
- Each fin 1 1 comprises a median zone 12 having a first end 13 connected to an internal fixing zone 14, intended to be fixed axially in the middle of the inner annular portion 6 of the support 5, and a second end 15 connected to an external zone fastener 16, intended to be fixed to the ejection cone 1, for example by screwing, riveting or brazing.
- the median zone 12 extending in a plane forming a non-straight angle relative to the tangent to the annular portion 6 passing through the first end 13.
- each median zone 12 extends in a plane parallel to the axis A of the inner annular part 6.
- outer fastening zone 16 has a cone portion shape complementary to the inner surface of the ejection cone 1 and the inner fixing zone 14 has a shape complementary to that of the inner annular portion 6.
- the annular portion 6 may also comprise chamfers turned radially inwards, at its ends, so as not to damage the tube 4 during assembly of the support 5.
- the fins 1 1 and the inner annular portion 6 are made of Nickel-based superalloy, for example INCONEL 625 (NiCr22Mo9Nb) or INCONEL 718, and the internal fixing areas 14 of the fins 1 1 are brazed on the
- the length of the inner annular portion 6 is less than or equal to 0.4 times its inner diameter.
- the inner annular portion 6 is a short guide forming, to a certain extent, a ball joint connection between the tube 4 and the support 5.
- the tube 4 is also freely mounted in rotation and in axial translation in the inner annular portion 6.
- the support zone of the tube 4 on the support 5 is situated axially in line with the zone for fixing the support 5 on the ejection cone 1, which allows the support 5 to have good rigidity.
- the fact that the fins 1 1 are inclined relative to the radial direction furthermore makes it possible to adequately withstand the effects of thermal expansions that may occur during operation.
