Abstract

L'invention concerne une chambre de combustion pour une turbomachine à gaz, comprenant des parois interne et externe (16") respectivement, un fond de chambre (20''), et un déflecteur (21'') disposé en aval du fond de chambre, pour le protéger thermiquement. Les parois interne et externe (16") et le déflecteur (21'') forment un ensemble monobloc (100).
