Combustor with baffled liners in a turbine engine

A combustor for a turbine engine, the combustor comprising:

• a dome;
• an outer liner comprising a plurality of outer liner holes and one or more outer liner dilution holes;
• an inner liner comprising a plurality of inner liner holes and one or more inner liner dilution holes, the dome, the outer liner and the inner liner defining a combustion chamber;
• an outer baffle connected to the outer liner to define an outer cavity therebetween, the outer baffle comprising a plurality of outer baffle holes;
• and
• an inner baffle connected to the inner liner to define an inner cavity therebetween, the inner baffle comprising a plurality of inner baffle holes,
• wherein the plurality of outer liner holes are configured to provide a partial air pressure drop across the outer liner and the plurality of inner liner holes are configured to provide a partial air pressure drop across the inner liner to cool down the outer liner and the inner liner,
• wherein the one or more outer liner dilution holes are configured to provide an additional pressure drop across the outer liner, and the one or more inner liner dilution holes are configured to provide an additional air pressure drop across the inner liner to enhance penetration of a jet airflow into the combustion chamber, and
• wherein the outer baffle comprises a forward outer baffle portion connected to a first end of a forward portion of the outer liner and to a second end of the forward portion of the outer liner, to define a forward outer cavity therebetween, and an aft outer baffle portion connected to a first end of an aft portion of the outer liner and to a second end of the aft portion of the outer liner, to define an aft outer cavity therebetween, the one or more outer liner dilution holes being provided between the forward outer cavity and the aft outer cavity, the forward outer cavity extending in a longitudinal direction from the first end of the forward portion of the outer liner to the second end of the forward portion of the outer liner, and the aft outer cavity extending from the first end of an aft portion of the outer liner to the second end of the aft portion of the outer liner in the longitudinal direction.
