Abstract

"pá de ventilação interna". a presente invenção refere-se a uma pá, por exemplo, de turbina à alta pressão, é concenida como uma divisória interna (9), a mais próxima da borda de escapamento (7), cuja parte superior (20) oblíqua em direção a essa borda, a fim de favorecer a ventilação de gás de resfriamento em direção aos orifícios (15) dessa borda, e mais geralmente a ventilação do canto superior, pela criação de novos orifícios (14) no topo (11) ou pelo deslocamento de orifícios (12) originários da segunda cavidade e levando ao intradorsoem direção à borda de escapamento.
