The invention concerns a multifunction probe for aircraft. The probe measures the total pressure and measures the total temperature of an air flow surrounding the aircraft. The total pressure is measured by a first tube, the so-called Pitot tube oriented substantially along the axis of the air flow
The invention concerns a multifunction probe for aircraft. The probe measures the total pressure and measures the total temperature of an air flow surrounding the aircraft. The total pressure is measured by a first tube, the so-called Pitot tube oriented substantially along the axis of the air flow surrounding the aircraft, the total temperature is measured by a second tube open to the air flow and oriented substantially in the axis of the air flow. The first tube is situated inside the second tube. The invention also concerns a process for shaping a heating wire forming means of deicing of the multifunction probe. The process includes: winding the heating wire helically around a first mandrel, inserting the first mandrel into a second hollow mandrel, continuing the winding of the heating wire around the second mandrel, and placing the heating wire, thus formed, inside the two tubes and being fixed therein.
