Abstract

Patente de Invenção: <B>"MéTODO E APARELHO DE CONTORNO EM DEGRAU DE LATERAL AQUECIDA DE COMBUSTOR, FACEANDO A PARTE POSTERIOR''<D>. Um revestimento de combustor apresenta uma superfície de revestimento escalonada e uma porção projetante formando uma fenda para ar de refrigeração. Uma borda contornada, faceando a parte posterior, da porção projetante reduz a turbulência do fluxo de gás de combustão e reduz uma área de superfície de revestimento de combustor, exposta aos gases de combustão. Uma cobertura de barreira térmica também é aplicada à borda contornada faceando a parte posterior, reduzindo o fluxo de calor para o interior da porção projetante e conseq³entemente reduzindo a temperatura de operação do revestimento de combustor. Assim sendo, a quantidade de ar de refrigeração é reduzida, o que pode reduzir a emissão de exaustão, aumentar o desempenho do motor e estender a vida útil da estrutura de combustor.
