청구항

We claim: 1. A combustor for a gas turbine engine comprising: an inner reverse-flow annular combustor liner; and an outer reverse-flow annular sheet metal combustor liner, the outer liner including a long exit duct portion adapted to redirect combustion gases in the combustor towards a combustor exit, the long exit duct portion of the outer liner including at least two discontinuities between smooth continuous wall portions on either side of the discontinuities, the wall portions intersecting each other at the discontinuities to define an obtuse inner a...
