Abstract (en)
The combustion chamber has pilot (11) and main (12) combustion zones with separate injectors (3,7;4,8) for fuel and oxidant, the assembly being held under pressure (P1) inside a housing (14). The system incorporates a regulating mechanism for the main oxidant flow which reacts to the pressure difference between the internal pressure (P1) and the atmospheric pressure outside the housing.
