Abstract

A piece of aeronautic equipment intended to equip an aircraft, the equipment piece ( 25 ) including at least one part intended to be arranged at a skin ( 27 ) outside of the aircraft and heating elements for that part, which include a thermodynamic loop including a closed circuit in which a heat transfer fluid circulates, the closed circuit including an evaporator and a zone in which condensation of the heat transfer fluid can occur in the appendage to heat it, outside the evaporator, the circuit in which the fluid circulates is formed by a tubular channel with an empty section, at least the part of the piece of equipment arranged outside the aircraft is made by additive manufacturing and includes a fastening base ( 120 ) for fastening on the skin of the aircraft from which support elements ( 130 ) for a Pitot tube ( 140 ) provided with lateral static pressure taps ( 150 ) extend.

First claim

The invention claimed is:

1. A piece of aeronautic equipment intended to equip an aircraft, the piece of equipment comprising at least one part intended to be arranged at a skin of the aircraft outside the latter and means for heating that part, characterized in that the heating means comprise a thermodynamic loop comprising a closed circuit in which a heat transfer fluid circulates, the closed circuit comprising an evaporator and a zone in which a condensation of the heat transfer fluid can occur in the appendage to heat the fluid, in that outside the evaporator, the circuit in which the fluid circulates is formed by a tubular channel with an empty section, in that at least the part of the piece of equipment arranged outside the aircraft is made by additive manufacturing and includes a fastening base for fastening on the skin of the aircraft from which support means for a Pitot tube provided with lateral static pressure taps extend.

2. The aeronautic equipment according to claim 1 , characterized in that the channel is configured for the fluid to circulate therein by capillarity.

3. The aeronautic equipment according to claim 1 , further comprising a circulation pump for the heat transfer fluid.

4. The aeronautic equipment according to claim 1 , characterized in that the tubular channel forms a single thermodynamic loop outside the evaporator.

5. The aeronautic equipment according to claim 1 , characterized in that the tubular channel forms several thermodynamic loops in which the heat transfer fluid circulates in parallel outside the evaporator.

6. The aeronautic equipment according to claim 1 , characterized in that the support means for the Pitot tube extending from the base comprise tubular means forming the tubular channel.

7. The aeronautic equipment according to claim 1 , characterized in that the part is an appendage configured to be arranged protruding relative to the skin of the aircraft.

8. The aeronautic equipment according to claim 7 , further comprising a base intended to fasten the piece of equipment on the skin of the aircraft, in that the appendage is arranged on a first side of the base and in that the evaporator is arranged on a second side of the base, opposite the first side.

9. A data file stored on storage means and able to be loaded in the memory of a processing unit associated with an additive manufacturing machine able to manufacture an object by superimposing layers of material, comprising data for three-dimensional depiction of the piece of equipment according to claim 1 , so as to allow, when the data file is loaded into memory of, and processed by, said processing unit, the manufacture of said piece of equipment by said additive manufacturing machine.
