Combustion chamber comprising a bottom wall comprising a plurality of partial truncated cones

摘要

The invention relates to a combustion chamber of a turbine engine of a general annular shape with respect to a geometrical axis (4), comprising an external wall (1), an internal wall (2) and a bottom wall which connects said external and internal walls, which bears fuel injection and oxidant admission devices (10) and which itself comprises a succession of elementary walls of a generally frustoconical shape each delimited by a face which is at least partially conical. According to the invention, the at least partially conical faces of two adjacent said elemental walls overlap, bringing about with one another and with said external and internal walls geometrical interferences, and are limited by the common cutouts (CR, L1, L2) of said geometrical interferences. An application is making a combustion chamber which allows non-polluting combustion. <IMAGE>
