Abstract
According to the invention, the wall ( ) is mounted movably as one so as to be able to slide longitudinally in translation, bringing the joint line ( ) closer to the fuel injector ( ) so as progressively to modify the geometries of the oxidant inlet ( ) and of the combustion chamber ( ), said geometries passing progressively from a first state (I) in which, for a Mach number lying between 1.5 and 3, said oxidant inlet ( ) constricts said oxidant flow only slightly and the combustion chamber ( ) is long and divergent, to a second state (III) in which, for a Mach number lying between 8 and 12, said oxidant inlet ( ) strongly constricts said oxidant flow and said combustion chamber ( ) is shorter and exhibits a constant cross section.
