Abstract
The invention relates to an aeronautical probe designed to be mounted on the skin of an aircraft and comprising a probe body protruding from the skin of the aircraft and a heater for de-icing an external surface of the probe body. According to the invention, the heater comprises two self-supporting electrodes and heating resistive elements. Each electrode is formed of an electrically insulating substrate and of an electrically active portion forming one face of the electrode in question. Each resistive element is in contact with the faces of the electrodes. The notable advantages of the invention are that it makes it possible to reduce the operating temperature of the resistive elements and the phenomena of fatigue in the mechanical link between the electrodes and the resistive elements due to different expansion coefficients.
