Combustion chamber comprising chamber end wall heat shielding deflectors and gas turbine engine equipped therewith

Abstract

An annular combustion chamber for a gas turbine engine is disclosed. The combustion chamber includes an external wall, an internal wall, a chamber end wall connecting these two walls and provided with openings for the fuel injection systems, and heat shielding deflectors fixed to the chamber end wall. The deflectors include a flat wall portion with an opening centered on said openings for the fuel injection systems, two longitudinal edges, and two transverse edges. Along one of the longitudinal edges, the deflector includes a tongue forming a joint cover, creating a housing along the edge for the edge of the adjacent deflector so as to seal the join between the two adjacent edges of the two deflectors. The tongue is spaced away from the chamber end wall so as to create a space supplied with cooling air via orifices in the chamber end wall.
