  • Patent number: 11365883
    Abstract: The invention relates to a bottom wall (118) of a gas turbomachine combustion chamber. This bottom wall comprises openings (119) for mounting combustion air supply systems and holes (128) for the passage of cooling air between at least one inlet (128a) and at least one outlet of said holes. The holes (128) extend inwardly along the bottom wall with the outlet port located closer to the opening (119) adjacent to it than the inlet hole.
    Type: Grant

  • Patent number: 11242994
    Abstract: A combustion chamber for a turbomachine having a bottom wall, at least one mixing bowl for promoting the mixing of air and fuel, mounted in an opening in the bottom wall, at least one annular baffle mounted axially downstream of the bottom wall, with respect to the direction of the gas flow within the combustion chamber, around the opening. The baffle is produced in one piece with the mixing bowl so as to form a one-piece assembly that has at least one channel for the flow of cooling air. The channel has an air inlet located upstream of the bottom wall and an air outlet located downstream of the bottom wall. The air outlet is located radially opposite the baffle.

  • Patent number: 11221141
    Abstract: A turbomachine includes a combustion chamber with a radially extending downstream flange at its downstream end. A distributor is disposed downstream of the combustion chamber and includes a platform from which at least one vane extends radially. The platform has an upstream edge extending radially and delimiting, with the downstream flange disposed opposite, a gap opening into the combustion chamber at its radially inner end and closed at its radially outer end by sealing means fixed to the distributor. The downstream flange of the combustion chamber has at least one rectilinear cooling orifice passing through the flange and opening into the gap opposite the platform of the distributor.
