Abstract
According to the invention, the wall (5) is mounted movably as one so as to be able to slide longitudinally in translation, bringing the joint line (14) closer to the fuel injector (9) so as progressively to modify the geometries of the oxidant inlet (16) and of the combustion chamber (15), said geometries passing progressively from a first state (I) in which, for a Mach number lying between 1.5 and 3, said oxidant inlet (16) constricts said oxidant flow only slightly and the combustion chamber (15) is long and divergent, to a second state (III) in which, for a Mach number lying between 8 and 12, said oxidant inlet (16) strongly constricts said oxidant flow and said combustion chamber (15) is shorter and exhibits a constant cross section.
