Abstract
A gas turbine engine comprises an annular combustor chamber formed between an inner liner and an outer liner. An annular upstream zone is adapted to receive fuel and air from an annular nozzle. An annular mixing zone is located downstream of the upstream zone. The mixing zone has a reduced radial height relative a downstream combustion zone of the combustion chamber, the mixing zone defined by straight wall sections.

A combustor comprising:
- an annular combustor chamber formed between an inner liner and an outer liner, an annular upstream zone adapted to receive fuel and air from an annular nozzle, and an annular mixing zone located downstream of the annular upstream zone and formed by a pair of annular wall portions, the annular mixing zone being radially outward of an inner one of the annular wall portions and being radially inward of an outer one of the annular wall portions, the annular mixing zone having a reduced radial height relative a downstream combustion zone of the combustion chamber and to a maximum radial height of the annular upstream zone, the annular mixing zone defined by straight wall sections of the pair of annular wall portions.
