Combustion chamber for turbine engine, has deflector extending annular wall towards interior of chamber and downstream, and diverting air from exterior towards interior and downstream of chamber

摘要

#CMT# #/CMT# The chamber has an annular wall (15) with passages (20) ensuring cooling of the chamber by air circulation through the passages. An air inlet orifice is located in a plane of an external surface of the wall and defined in downstream by an external part of a downstream edge (25) of each passage. An air outlet orifice is defined by an internal part of the downstream edge and by a downstream edge (35) of a deflector (30). The deflector extends the wall towards interior of the chamber and downstream, and diverts air from exterior towards interior and downstream of the chamber. #CMT# : #/CMT# An independent claim is also included for a method for forming passages in an annular wall of a combustion chamber. #CMT#USE : #/CMT# Combustion chamber for a turbine engine. #CMT#ADVANTAGE : #/CMT# The deflector extends the wall towards interior of the chamber and downstream, and diverts air from exterior towards interior and downstream of the chamber, thus permitting the air to move from upstream towards downstream, which is effectively guided by the passages towards interior of the chamber for facilitating effective cooling of the wall, and hence reducing a number of passages carrying out cooling of the wall at low manufacturing cost. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a passage of an annular wall of a combustion chamber. 15 : Annular wall 20 : Passages 25, 35 : Downstream edges 30 : Deflector 34 : Lateral extension.
