Abstract

"MARTELAMENTO POR CHOQUE A LASER DE ARESTAS DE PALHETA DE ROTOR INTEGRALMENTE EQUIPADO COM PALHETAS". Processo para martelar por choque a laser arestas dianteira e traseira (LE, TE) de palheta de rotor (108) de discos e rotores de motor turbina a gás integralmente equipados com palhetas que não são bloqueados por outras fileiras de palhetas. O processo inclui disparar continuamente um feixe laser estacionário (102), cujos pulsos repetitivos entre períodos relativamente constantes, ao longo de no mínimo uma porção de arestas dianteira ou traseira (LE, TE) da palheta (108), com o feixe laser (102) projetado com um ângulo oblíquo (110) com relação a uma superfície da aresta de tal modo que pulsos laser formem pontos de laser de conformação elíptica (60) que se superpõem. Na configuração da invenção tomada como exemplo, os pontos de laser de confirmação elíptica (60) têm uma superposição de cerca de 50% e são da ordem de 11,7 mm por 4 mm em diâmetro. Um outro processo é para martelar por choque a laser arestas dianteira e traseira de palheta de rotor (LE, TE) de motor turbina a gás com rotores e discos integralmente equipados com palhetas que são bloqueados por outras fileiras de palhetas. O processo inclui disparar continuamente o feixe laser estacionário (102) que pulsa de maneira repetitiva entre períodos relativamente constantes, ao longo de no mínimo uma porção das arestas dianteira ou traseira (LE, TE) da palheta (108), com o feixe laser (102) inclinado de maneira composta de tal modo que ele seja projetado em um primeiro ângulo oblíquo (110) com relação a uma superfície da aresta e em um segundo ângulo oblíquo (114) com relação a um eixo ao redor do qual o rotor é circunscrito. Pulsos laser formam pontos de laser de conformação elíptica (60) que são inclinados a partir da aresta dianteira (LE) radialmente para dentro no sentido do eixo. Na configuração tomada como exemplo, os pontos de laser de conformação elíptica (60) têm uma superposição de cerca de 50%.
