<p>The invention relates to a turbine engine combustion assembly comprising a casing, a combustion chamber, and at least one fuel injector for starting a turbine engine , said combustion chamber being defined by two walls of revolution , namely an internal wall and an external wall extending one inside the other and being connected by an annular chamber base wall. The external wall of the chamber is secured to an annular external wall of the casing. The injector is attached to the annular external wall of the casing and comprises a fuel ignition enclosure extending inside the casing successively through an opening in the casing wall and an opening in the external wall of the combustion chamber before opening into said chamber. At least one wall of the ignition enclosure that extends between the casing wall and the combustion chamber wall is provided with at least one air intake port. The combustion assembly is characterised in that the external wall of the combustion chamber is solidly connected to a device for plugging the air intake port(s) according to the thermal expansion state of the combustion chamber.</p> |
