Abstract
A combustion chamber for a gas turbine engine, comprising an upstream porn divided longitudinally into a first chamber and a second chamber supplied with air in parallel, and a downstream portion in which the flows issuing from these two chambers mix, the first chamber comprising a primary combustion zone into which fuel is injected at an idling rating forming a substantially stoichiometric air - fuel mixture, and a secondary combustion zone supplied with secondary combustion air, and the second chamber, of the premixed burning type, being formed by a simple conduit upstream of which, for driving the gas turbine at the maximum rating, supplementary fuel is injected which burns on contact with a flame synchronizer.
