Abstract

Patente de Invenção: "MéTODO E APARELHO PARA REDUçãO DE TENSãO EM CIRCUNFERêNCIA EM ARO DE ESTRUTURA DE ROTOR". Estrutura de rotor (10) para um motor de turbina a gás (12) opera com tensão circunferente reduzida. A estrutura de rotor inclui um rotor (14), incluindo uma pluralidade de lâminas de rotor (26), que se estendem de forma radial para o exterior, a partir de um aro anelar (20). Um filete de raiz ou base (80) se estende de forma circunferente em torno de cada lâmina, entre as lâminas e o aro. O aro inclui uma superfície externa (28), incluindo uma pluralidade de indentações cóncavos (90) que se estendem entre lâminas de rotor adjacentes e formando um raio composto. Cada indentação se estende a partir de uma borda de condução (40) das lâminas de rotor, em direção à borda de rastreamento (42) das lâminas de rotor.
