Definitions

  • the present invention relates to the specific field of turbomachinery and it is more particularly interested in the problem posed by the assembly of a CMC type composite material combustion chamber (ceramic matrix composite) in the metal housings of a chamber turbine engine.
  • CMC type composite material combustion chamber ceramic matrix composite
  • the turbine high pressure in particular its inlet distributor (HPT nozzle), the combustion as well as the inner and outer casings (or casings) of this chamber are made of the same material, generally metallic.
  • HPT nozzle inlet distributor
  • the combustion as well as the inner and outer casings (or casings) of this chamber are made of the same material, generally metallic.
  • the use of a chamber metal proves from a thermal point of view totally unsuitable and it must be used a chamber based on high temperature composite materials such as CMC.
  • the difficulties of implementation and the cost of these materials make that their use is most often limited to the combustion chamber it same, the inlet distributor of the high pressure turbine and the casings internal and external of the chamber then remaining produced more conventionally in metallic materials.
  • Gold, metallic materials and composite materials have very different coefficients of thermal expansion. This results in particularly acute problems of connection with the internal and external envelopes of the combustion and interface chamber at the distributor, at the inlet of the high pressure turbine.
  • the present invention overcomes these drawbacks by proposing an assembly of the combustion chamber in the crankcases having the capacity to absorb the displacements induced by the differences in the expansion coefficients of these rooms.
  • An object of the invention is also to propose an arrangement which benefits the better existing characteristics of the combustion chamber.
  • a turbomachine comprising, in internal and external annular envelopes of metallic material and in a direction F gas flow, a fuel injection assembly, a annular combustion of composite material having a longitudinal axis, and a annular distributor made of metallic material forming the paddle inlet stage stationary of a high pressure turbine, characterized in that said combustion of composite material is maintained in position between said internal and external metallic annular envelopes by a plurality of flexible tongues, the first ends of said tongues being connected between them by a metal crown fixed integrally to each of said internal and external metallic annular envelopes by first means of fixing and second ends being fixed by second means of attachment to a crown of composite material fixedly attached to said combustion chamber of composite material, the flexibility of said tabs of fixing allowing at high temperatures a free radial expansion of said combustion chamber of composite material with respect to said casings metallic annulars.
  • the first and second fixing means preferably consist by a plurality of bolts.
  • each of said metallic ring envelopes is formed in two parts
  • said crown metallic connecting together said first ends of said tabs of metal fixing is mounted between the connecting flanges of these two parts.
  • said metal crown can be fixed directly to said annular casing by fixing means.
  • said first ends of the fixing tabs can either be fixed by soldering to said crown either be a single piece with this metal crown.
  • said composite crown is brazed on a downstream end of the combustion chamber.
  • this composite crown is sewn on this downstream end.
  • this composite crown is installed on this downstream end.
  • Said composite crown comprises a determined part forming a support surface for a seal (advantageously of the circular seal type "Lamellae") sealing the gas stream between said chamber combustion and said distributor.
  • said determined part is a end part of said composite crown.
  • the distributor is fixed on a downstream part 14b of the annular casing internal of the turbomachine by first removable fixing means preferably consisting of a plurality of bolts 50 while resting on support means 49 secured to the outer annular envelope of the turbomachine.
  • Passage orifices 54, 56 formed in the metal platforms external 46 and internal 48 of the distributor 42 are further provided to ensure cooling of the stationary vanes 44 of this distributor at the inlet of the rotor of the high pressure turbine from the compressed oxidizer available at the outlet of the diffusion duct 18 and flowing in two streams F1, F2 on either side of the combustion chamber 24.
  • the combustion chamber 24 which has a coefficient of thermal expansion very different from other metal parts forming the turbomachine, is fixedly held in position between the annular casings internal and external by a plurality of flexible tabs 58, 60 regularly distributed around the combustion chamber.
  • These mounting tabs are mounted for a first part of them (see tab referenced 58) between the outer annular envelope 12a, 12b and the outer axial wall 26 of the combustion chamber and for a second part (like the tongue 60) between the internal annular envelope 14a, 14b and the internal axial wall 28 of the chamber combustion.
  • Each flexible fixing tab made of metallic material which can have a substantially triangular shape as illustrated in FIG. 1A, or consist of a simple blade (of constant width or not), is welded or brazed by a first end 62; 64 to a metal crown 66a, 66b fixed together by first fixing means 52; 68 to either (depending on its location) external metallic annular envelopes 12 or internal 14 and intended to facilitate both the maintenance of these tabs and sealing against the annular space 16.
  • these tongues and the metal crown together form a part single metal in one piece.
  • this tongue is fixed integrally by second fixing means 74, 76 to a ceramic composite crown 78a; 78b brazed on a downstream end 88; 90 of external axial 26 and internal 28 walls of the material combustion chamber ceramic composite.
  • This solder can be replaced or reinforced by a sewing.
  • the connection between the chamber walls and the crowns can also be performed entirely by implantation (type bond known as anglemia "Pin'sée").
  • the number of tabs can, for example, be in number equal to that of the injection nozzles or equal to a multiple of this number.
  • FIG. 1 illustrates a first embodiment of the invention in which the second ends of the tabs 70, 72 are fixed respectively on the composite ceramic outer 78a and inner 78b crowns with a simple bolting (but crimping as illustrated in the partial view of Figure 1B would also be possible).
  • the metal crown 66a, 66b connecting the first ends 62, 64 of the tongues is preferably taken between existing connection flanges between the upstream and downstream parts of the enclosures internal 14 and external 12 annulars and fixedly held by the first fixing means 52, 68 which preferably are also of the bolt type.
  • washers made of ceramic composite material 74a; 76a for allow to "drown" the conical heads of the bolts screws forming the second fixing means 74; 76.
  • the metal ring 66a connecting between them by welding (or brazing) the first ends 62 of the tabs of fixing 58 of the external axial wall of the combustion chamber 26 is no longer mounted between flanges but itself welded (or brazed) at a key 106 integral with the outer annular casing 12.
  • the metal crown 66b connecting together by welding (or brazing) the first ends 64 of fastening tabs 60 of the internal axial wall of the combustion chamber 28 is no longer mounted between flanges but simply fixed directly to the internal annular casing 14 by fixing means 108, for example of bolt type.
  • the tightness of the gas stream between the combustion chamber 24 and the distributor 42 is provided by a “lamellar” circular joint 80, 82 mounted in a groove 84, 86 of each of the external 46 and internal 48 platforms of the distributor and which comes to rest directly on a part of the crown ceramic composite 78a; 78b forming a support plane for this circular joint sealing.
  • This part can be an end part of the crown.
  • Gasket is kept in abutment against this end part of the composite crown or any other part by means of an elastic element, of the circular spring type with blades 92, 94, fixed on the distributor. This provision ensures a perfect tightness of the hot stream between the combustion chamber 24 and the distributor 42.
  • the flexibility of the tabs of fixing allows to support the thermal expansion gap appearing at high temperatures between the composite material combustion chamber and the metallic ring envelopes while ensuring the maintenance and positioning of the chamber.
