A leading edge member of an airfoil of an aircraft has an outside wall defining a wing span and a deicing device for circulating hot air in the direction of the wing span of the airfoil. The device includes a hot air distribution duct extending inside the leading edge member in the direction of the span of the foil. The duct has a plurality of orifices distributed over at least part of its length. A hot air supply communicates with one end of the distribution duct. The hot air supply is connected by ducts located outside the leading edge member to at least one propulsion engine of the aircraft.

1. A leading edge member of an airfoil of an aircraft having an outside wall and a de-icing device for circulating hot air in a direction of a span of said airfoil, said de-icing device comprising a hot air distribution duct extending longitudinally inside said leading edge member in said direction of said span and spaced from said outside wall, said distribution duct having two open ends defining a length of said duct with a plurality of orifices distributed over at least a part of said length between said two ends and, a hot air supply duct communicating with one of said ends of said distribution duct for hot air flow through said distribution duct and longitudinally along said outside wall, said hot air supply duct connected to at least one propulsion engine of said aircraft.
