Definitions
- the present invention relates to a turbojet diffuser, this diffuser being arranged between a compressor and a chamber of combustion in the turbojet.
- the diffuser is often fixed inside an outer casing of the combustion chamber by a thin wall or a frustoconical web extending from a longitudinal wall external diffuser in the direction of the combustion chamber and which is welded at its radially outer end to the outer casing of the combustion chamber.
- the purpose of the invention is in particular to provide a simple solution, inexpensive and economical solution to the problem of the dismountable diffuser in a turbojet.
- a diffuser for turbojet engine this diffuser being arranged between a compressor and a combustion chamber and fixed to an outer casing of the combustion chamber by means of suspension that extend between this outer casing and a wall outer longitudinal axis of the diffuser, characterized in that the means for suspension comprise a first frustoconical wall extending from the outer longitudinal wall of the diffuser in the direction of the chamber of combustion, and a second frustoconical wall connected to the first wall frustoconical and extending between the first frustoconical wall and the casing outside the combustion chamber in the direction of the compressor.
- the two frustoconical fastening walls of the diffuser according to the invention make it possible to circumvent the downstream advancement of space ring that surrounds the compressor and therefore to fix the diffuser to the housing outside the combustion chamber without changing the specifications of compressor air sampling and without the use of structural arms.
- the attachment of the second frustoconical wall on the outer casing of the combustion chamber is at the level of connection between the outer casings of the compressor and the chamber of combustion, particularly simple by inserting a flange annular of the aforementioned second frustoconical wall between the flanges annular connection of compressor housings and chamber annular.
- first frustoconical wall of suspension means is connected to the upstream end of the wall outer longitudinal section of the diffuser, which ensures optimal alignment of the upstream end of the diffuser on the downstream end of the compressor, so a fixed blade of the upstream end of the diffuser is well positioned and centered on the axis of the compressor.
- the biconical shape of the suspension means increases the flexibility of the diffuser attachment and reduces the constraints on the connection on the external longitudinal wall of the diffuser, which increases its life.
- the two walls or frustoconical webs of the suspension means are formed of a single piece and their junction comprises a rib ring extending towards the combustion chamber.
- This annular rib stiffens the junction area of the two walls or sails frustoconical and distributes the stresses in this area.
- She has preferably a thickness between 1.3 and 1.7 times the thickness of the sails, and optimally a thickness equal to about 1.5 times the thickness of the sails.
- This rib has, in its simplest embodiment, a shape cylindrical centered on the axis of the turbojet engine.
- it can extend in the extension of the bisector of the angle formed between the two walls or frustoconical sails suspension means of the diffuser.
- an advantage of the diffuser according to the invention is it can be dismounted in a simple way while respecting the specifications compressor air sampling.
- reference numeral 1 denotes a diffuser according to the technique known, arranged between a compressor 2 upstream and a chamber of combustion 3 downstream in a turbojet engine.
- the compressor 2 is a high pressure compressor and includes several stages of moving blades 4, 5 mounted on a rotor 6 of the turbojet engine by suitable means for example of the type with a tail dovetail 7, and fixed blade stages 8 forming rectifiers, mounted on a stator 9 of the turbojet engine by appropriate means.
- Figure 1 represented only two stages of moving blades 4 and 5 and a blade stage fixed 8 between the two stages of blades 4 and 5.
- An annular space 10 is delimited around the stator 9 of the compressor 2 by an outer casing 11 and a transverse wall rear 12 which is mounted by an inner annular flange 13 on a flange annular 14 of the stator 9 and an external annular flange 15 on a flange ring 16 of the outer casing 11 of the compressor 2.
- the combustion chamber 3 is delimited by an outer casing 17 and by an inner casing (not shown), the outer casing 17 being fixed on the upstream side on the outer casing 11 of the compressor 2 by means of a annular flange 18 applied to the outer annular flange 15 of the wall transverse 12 of the compressor 2, the fixing of the three flanges being ensured by appropriate means of the screw-nut type 19.
- the rear transverse wall 12 extends downstream around an upstream part of the diffuser 1.
- the diffuser 1 comprises fixed vanes 20 arranged radially between an outer longitudinal wall 21 and an inner longitudinal wall 22 for guiding the air leaving the compressor 2 to the chamber of combustion 3.
- the diffuser 1 is fixed to the lower part of the outer casing 17 of the combustion chamber 3 by a thin wall or sail 23 of frustoconical shape which extends from the outer longitudinal wall 21 of the diffuser 1 in the direction of the firebox 3 and that is welded at its radially outer end 24 to the outer casing 17 of the combustion chamber 3.
- the wall or sail 23 of frustoconical shape is attached to the outer longitudinal wall 21 of the diffuser in the part median of this wall 21.
- the diffuser 1 is also fixed by a wall or internal sail 25 of frustoconical shape which extends from the wall internal longitudinal 22 of the diffuser 1 in the direction of the chamber of combustion 3, to an internal casing (not shown) of the chamber of
- a cylindrical wall 26 extends from the wall external longitudinal 21 of the diffuser 1 in the direction of the compressor 2 and is fixed on the stator 9 of the compressor 2 by means of a flange ring 27 applied to the connection flanges 14 and 13 of the stator 9 and the transverse wall 12 of the compressor 2 respectively, the fixation being provided by appropriate means 28 of the screw-nut type.
- This diffuser of the prior art is not removable independently of the casings of the combustion chamber.
- FIG. 2 shows a diffuser 29 according to the present invention, arranged between a compressor 2 and a combustion chamber 3 of the same type as those previously described.
- the diffuser 29 comprises fixed vanes 30 arranged radially between its outer longitudinal wall 31 and its longitudinal wall internal 32 for guiding the air output of the compressor 2 to the combustion chamber 3.
- the diffuser 29 is mounted inside the outer casing 17 of the combustion chamber 3 by suspension means which comprise a first wall or sail 33 of frustoconical shape which extends from the outer longitudinal wall 31 of the diffuser 29 in the direction of the combustion chamber 3 and a second wall or sail 34 of shape frustoconical extending between the first frustoconical wall 33 and the housing outside 17 of the combustion chamber 3 in the direction of the compressor 2 and ends with a radially outer annular flange 35 clamped between the connecting flange 15 of the transverse wall 12 of the compressor 2 and the upstream flange 18 of the outer casing of the chamber of combustion 3, the annular flange 16 of the compressor housing being applied to the annular flange 15 of the transverse wall 12.
- the diffuser 29 also comprises an inner wall or sail 36 of frustoconical shape extending from the inner longitudinal wall 32 of the diffuser 29 into the direction of the combustion chamber 3 and which is fixed at its end downstream (not shown) on the internal casing of the combustion chamber 3.
- the two walls or sails 33 and 34 frustoconical means of suspension are formed of a single piece and their junction includes a annular rib 37 which extends towards the combustion chamber 3 and which makes it possible to stiffen the junction zone of the two walls 33 and 34 and to distribute the constraints in this area.
- the annular rib 37 has a thickness of between 1.3 and 1.7 times the thickness of the sails 33 and 34, and is preferably equal to 1.5 times about the thickness of the sails 33 and 34.
- This annular rib 37 is for example of cylindrical shape and centered on the axis (not shown) of the turbojet engine. Alternatively, she extends in the extension of the bisector of the angle formed between two walls or sails 33 and 34 frustoconical suspension means.
- the radius of the connection 38 between the upstream side surfaces of two frustoconical walls 33, 34 is for example three millimeters about.
