Abstract

L'invention concerne un mode de refroidissement pour ailette de moteur à turbine à gaz. Sur la face inférieure interne de la partie avant de l'ailette sont formées des nervures 21, 22, 23 pourvues de rainures 24, 25, 26, 27 dans lesquelles sont montées des plaques perforées 28, 29 dirigeant l'air provenant de la partie avant de l'ailette vers les orifices 32, 33 produisant un refroidissement par circulation laminaire sur le flanc concave de l'ailette.
