Abstract:
A gas turbine engine combustor (20) has inboard and outboard walls (32,134). A forward bulkhead (36) extends between the walls and cooperates therewith to define a combustor interior volume. In longitudinal section, a first portion (54) of the combustor interior volume converges from fore to aft and a second portion (56), aft of the first portion (54) converges from fore to aft more gradually than the first portion (54).
Abstract:
In a method of combusting fuel in the combustion chamber (11) of a gas turbine engine, fuel and a first predetermined amount of air are injected into the combustion chamber to form a fuel-rich mixture, and a second predetermined amount of air is injected downstream, to mix with the mixture and form a lean fuel-air mixture. The combustion chamber (11) has a fuel injector (10) and inlets (17, 19) downstream thereof to allow the air to be injected.
