Definitions
- the subject of the invention is a device for ventilating a turbomachine ring.
- the problem we are trying to solve here is the machine yield loss that the subtraction of the induced ventilation flow: on seeks to limit this flow to the minimum necessary for a good ventilation.
- the solution chosen consists of arrange in the room behind the ring, and in which the gas supply duct opens, a annular distributor comprising a pierced wall holes and a cover placed between the wall and the conduit and pierced with other orifices, intended for restrict the flow of gas; these holes of lids are fewer and have a section total smaller than the holes in the wall.
- a stator 1 of a turbomachine is equipped spacers 2 (only one of which is shown) intended to support as many 3 rings which contribute to delimit the gas flow stream of the machine in front of circular stages of moving rotor blades 4.
- the subject of the invention is an annular housing 5 composed of a cover 6 and a wall 7.
- the housing 5 is housed in a room 8 delimited by the spacer 2 and the ring 3, and it cuts it between this and the outlet 9 of a gas supply circuit relatively fresh from the bottom of the combustion; the rest of the power circuit is not shown because it is not original, but we may refer to French patent 2,416,345 cited higher for more detail.
- the integrity of the case 5 is ensured by providing the cover 6 and the wall 7 lateral edges 10 and 11 circular and likewise diameter which are joined in pairs by welds, rivets or other means; the side edges 11 of the wall 7 are also fixed to the spacer 2.
- the wall 7 is foraminated, that is to say pierced with numerous orifices 12, here substantially more long as wide thanks to their finesse and fairly large wall thickness 7.
- the cover 6 is pierced by other holes 13, less numerous than those 12 of wall 7 but whose cross section opening hours is also quite small. They are established at the top of projections 14 obtained by pushing back the material of the cover 6 towards the outside of the case 5 and whose shape is more or less conical so that the orifices 13 communicate with the interior of the housing 5 by pavilions 15 opening towards the wall 7.
- the gas entering chamber 8 accumulates in front of the housing 5 and passes through the holes 13 then 12 to come and lick the ring 3 before being evacuated in the gas flow stream passing through holes 16 drilled through the ring 3.
- the constitution of orifices 13 precisely calibrated allows to restrict the gas flow through them without excessively reducing the flow load thanks to the flared shape of the pavilions 15.
- the projections 14 can however be oriented to favor the mean direction of gas flow in the box 5 to one region or the other of the wall 7.
- the gas flow is therefore distributed properly in the housing 5 and flows out through the orifices 12, who distribute it by directing it with precision and with the desired spatial distribution towards different portions of the ring 3.
- the density and direction of the orifices 12 can therefore vary over the wall 7.
- the conception of the invention is certainly applicable to other parts of the machine than the high pressure turbine rings, and it can also be used with charged gases to warm up the structure on which they are blown.
