Abstract

1/1 resumo “câmara anular de combustão de uma turbomáquina” a invenção se refere a uma câmara anular de combustão que inclui duas paredes de revolução interna e externa, ligadas à montante por uma parede 5 anular de fundo de câmara atravessada por sistemas de injeção que incluem cada um ao menos uma verruma destinada a produzir um fluxo de ar girando à jusante de um injetor de combustível e uma tigela (78) em formato de tronco de cone à jusante da verruma e formada por uma série anular de orifícios de injeção de ar (80, 86), a parede de revolução externa incluindo uma série anular de orifícios primários de 10 diluição. os orifícios (80, 86) das tigelas (78) são repartidos e dimensionados de modo que as camadas de mistura ar/combustível apresentem um alargamento local que intercepta circunferencialmente uma camada de combustível adjacente à montante dos orifícios primários de diluição.
