Abstract
The invention relates to a de-icing splitter nose () of an axial turbine engine, notably a de-icing splitter nose of a turbo-jet engine compressor. The splitter nose includes an annular row of vanes (), each of which has a radially extending leading edge (), and a de-icing system () based on hot-air injection. The injection is pulsed, i.e. discontinuous. The system () includes an annular row of injection orifices for injecting de-icing fluid () onto the vanes () in respective injection directions (). Each injection orifice is associated with a vane such that the injection directions thereof are substantially parallel to the leading edge () of the related vane, enabling said vane () to be de-iced.
