A device for de-icing a wall of a leading edge 100 of a turbine engine, said leading edge cooperating with a downstream guide vane 102 subjected to a flow of fluid. The device comprises first fluid flow means 203 along an upper zone 204 of the downstream guide vane so as to guide the fluid to the wall of the leading edge, and a second fluid flow means along a lower zone of the downstream guide vane so as to evacuate the fluid from the leading edge. The first flow means are arranged such that the wall of the leading edge is impacted by the fluid along a non-orthogonal direction. The first fluid flow means may comprise grooves or notches formed in the upper zone of the downstream guide vane. The fluid may impact the wall at an angle to the orthogonal direction of more than 10º, and preferably between 30º and 60º. |
