Abstract

resumo patente de invenção: "rotor de um turboalimentador de gás de escape". a presente invenção refere-se a um rotor de um turboalimentador de gás de escape que tem um cubo de rotor e palhetas de rotor dispostas no dito cubo de rotor. as palhetas de rotor têm uma distribuição de espessura de palheta selecionada para que essas palhetas de rotor tenham, ao longo de sua extensão da borda anterior de fluido (4) até a borda posterior de fluido (5), pelo menos uma transição entre uma distribuição de espessura de palheta orientada por dureza e uma distribuição de espessura de palheta orientada por estresse e inércia em relação à altura da palheta.
