Definitions
- TITLE Measuring equipment including a heating device
- the present invention relates to measuring equipment comprising a heating device, said measuring equipment being intended to be placed outside and at skin level of a vehicle capable of moving in a hostile climatic environment associated with conditions icing climates, said equipment corresponding to a body formed of a mat carrying a closed tube at one of its ends, the heating device being intended to be housed within said tube and comprising at least one heating wire wound in the body of said tube
- the invention also relates to an aircraft comprising such measuring equipment.
- the invention relates to the field of heating measuring equipment intended to be placed on the skin of a vehicle capable of moving in a hostile climatic environment associated with icy climatic conditions, and in particular icy climatic conditions. supercooled water or freezing weather conditions crystals.
- Such equipment corresponds for example to civil or military aeronautical measuring equipment comprising flush parts or appendages emerging from the skin of the aircraft (i.e. located outside the aircraft).
- such equipment is ground measuring equipment for military, scientific or even meteorological fields, in particular for measurements in a context of extreme polar cold.
- the incidence probes may include mobile appendages intended to orient themselves in the axis of the air flow surrounding the probe. The orientation of the probe makes it possible to determine the incidence of the air flow.
- Other angle of attack probes can be equipped with fixed appendages equipped with several pressure ports. The pressure difference measured between these pressure taps also makes it possible to determine the incidence of the air flow surrounding the probe.
- the aircraft When flying at high altitude, the aircraft may encounter icing conditions.
- frost can form on the skin and on the appendages of the aircraft.
- the appearance of frost is particularly problematic for aerodynamic probes whose profiles can be modified by frost and whose pressure ports can be obstructed.
- the presence of frost is likely to distort the total pressure measurement of the probe and possibly render it inoperative in certain climatic conditions.
- reheating is in most cases carried out by means of one or more heating wires wound and embedded in the appendages, the reheating being done by the Joule effect. For example, to heat a total pressure probe, it is necessary to dissipate several hundred watts.
- this type of probe is made up of a mast carrying a closed tube at one of its ends and called a Pitot tube, or this type of probe is a Pitot-static probe.
- Heating of the probe is carried out by means of one or more heating wires, forming a heating resistance, wound (i.e. shaped in the form of a coil) in the body of the probe, i.e. say both in the mast and in the Pitot tube 10, the Pitot tube being illustrated in Figure 1.
- a Pitot tube 10 has at an open end 12 allowing in particular the measurement of the total atmospheric pressure.
- such a tube optionally has an internal tube 14, located inside the total tube 16. Between these two tubes 14 and 16, a space 18 is intended for the insertion of the wire heating.
- an electrical conductor comprising an alloy of iron and nickel coated with an electrical but not thermal mineral insulator such as alumina or magnesia is commonly used.
- the insulator is itself coated with a sheath of nickel, nickel chromium, or inconel allowing the brazing of the wire to the body of the probe.
- a heating wire corresponds to a metal sheathed coaxial, or as an alternative to a shielded spiral wire.
- the shaping of the heating wire also hereinafter referred to as "winding", within the Pitot tube 10, with or without internal tube 12, is complex and aims to enable a high density of heat to be provided regularly. distributed along the wall of the tube 10 of very small size, compared to the possibilities of forming the wire), and above all as close as possible to its open end 12 the most critical for anti-icing and de-icing, particularly in supercooled water.
- this heating element generally of the metal-sheathed coaxial heating wire type, in the tube 10 of the Pitot or Pitot static pressure probe impacts the defrosting capabilities, in particular of defrosting with supercooled water.
- Figure 2 illustrates a pinned winding based on the use of a pin 20 positioned along the radial axis of the internal tube 14 of Figure 1, the internal tube 14 being not shown in Figure 2 for simplification purposes.
- the heating wire is first bent at mid-length to make a loop 22, the loop 22 then being attached to the pin 20.
- the “double wire” corresponding to the two branches of the loop 22 is simply wound, in a single thickness, over a predetermined length with a predetermined pitch on the internal tube 14 of Figure 1 and a winding template, the winding (i.e. winding) being carried out in a forward direction facing the open end 12 of the Pitot tube towards the rear of the probe.
- the pinned winding is not optimal mainly due to the loop 22 which surrounds the pin 20, the diameter of this loop 22 forcing the second double-wire turn 24 of the heating wire coil to be moved back.
- This offset generates empty spaces 26 between the turns of the heating wires, due to the initial forming loop 22, the surface of these empty spaces 26 being too large in proportion to the surface heated directly.
- the density of heating wire is therefore lower than on the rest of the winding while it is precisely at the open end 12 of the probe that the most power must be provided.
- This technological limitation is today compensated for by ensuring that the complete winding has enough power to transfer it forward by thermal conduction, but the disadvantage is overheating of the nose of the Pitot tube on the ground or in conditions non-icing.
- such voids 26 are potentially conducive to corrosion because they are capable of filling with pollution from the environment of the vehicle on which the measuring equipment comprising said tube 10 is placed.
- Figure 3 represents another solution from the state of the art corresponding to round-trip winding as disclosed in patent EP 3 173 797 B1.
- Such a round-trip winding consists of winding the heating wire in single (and not in double-wire as for the pinned winding previously described in relation to the figure 2) on a template, then the internal tube 14 (not shown in Figure 3 for simplification purposes) in a first direction “going” from the rear to the front 12 of the probe.
- the winding is continued in the same direction of rotation but winding over the initial winding (ie coaxially) in a second "return” direction from the front 12 towards the rear of the probe, opposite in direction (ie opposite direction) to the first “go” direction from the rear to the front 12 of the probe.
- such a “round trip” winding in Figure 3 proposes to reduce the empty spaces 26 of the pinned winding, by a “double winding” corresponding to a coaxial superposition of the wound wire, but thus creating an “overdensity” of heat which can be detrimental to the lifespan of the heating wire, and what is more, by not allowing the power necessary for defrosting to be optimized, by the creation of zones without direct heat exchange with the zones to be heated.
- Another solution from the state of the art consists of using part of a non-self-regulated bi-material heating wire on the first turns of the winding at the nose of the Pitot tube, to avoid losing heat. local heating capacity when conditions at the nose are severe, the resistance of the wire decreasing with temperature in more classic structures.
- the use of a bi-material heating wire is expensive and presents risks in terms of reliability, in particular due to a potential breakage of the wire at the junction of the two materials constituting it.
- the aim of the present invention is therefore to overcome the drawbacks of the aforementioned state of the art, by proposing a new solution for shaping a heating wire (ie a new type of winding) in order to integrate an optimal length of wire in the little space offered by the tube 10, and this by seeking to position the greatest density of heating wire towards the front of the measuring equipment , that is to say near the open end 12 of the tube, to guarantee maximum heat is provided to the nose of the measuring equipment, the nose being the part most exposed to hostile external climatic conditions, such as supercooled water icing weather conditions or crystal icing weather conditions.
- a heating wire ie a new type of winding
- the invention relates to measuring equipment comprising a heating device, said measuring equipment being intended to be placed outside and at the level of the skin of a vehicle capable of moving in an environment hostile climate associated with freezing climatic conditions, said equipment corresponding to a body formed of a mat carrying a closed tube at one of its ends, the heating device being intended to be housed within said tube and comprising at least one heating wire wound in the body of said tube, the winding of said heating wire is a round-trip bridged winding defined by the presence of a bridge, the bridge corresponding to a portion of heating wire overlapping, along the axis of said tube, a predetermined number of turns of the end of said coil located near the open end of said tube, said overlapped turns being regularly spaced according to a predetermined pitch associated with the overlapping zone.
- Such a “bridged winding” proposed according to the present invention makes it possible to increase the heating density at the front open end of the tube, which is the critical zone for anti-icing or defrosting of the probe in icing supercooled water conditions. , but also on a smaller scale in crystal icing conditions.
- the principle of the present invention therefore consists of removing the pin and the initial forming loop of the pinned winding in order to be able to arrange the winding turns regularly spaced, while carrying out the return path of the wire parallel to the axis of revolution of the winding and in a heat exchange zone with the zones to be heated in order to limit superpositions and therefore heat losses.
- the bridge of the bridged winding according to the present invention makes it possible to obtain a "round-trip" winding almost in single thickness and not in double thickness according to the aforementioned state of the art relating to round-trip winding as disclosed within of patent EP 3 173 797 B1.
- the only zone of double thickness according to the present invention is limited to the overlap zone and has a surface limited to the contact surface between the wire of the bridge and the turns that the bridge overlaps (ie spans), so that there Heat generation associated with this reduced contact surface is negligible in terms of thermal loss.

- the winding of said heating wire is a round-trip bridged winding defined by the presence of a bridge P, the bridge P corresponding to a portion of heating wire overlapping, along the axis 36 of said tube, a predetermined number of turns of the end of said winding located near the open end 12 of said tube 10, said overlapped turns being regularly spaced according to a predetermined pitch associated with the overlapping zone .
- each end of the bridge is used to form a turn.
- the predetermined number of worst overlaps is strictly less than the total number of turns minus one.
- each turn forming the winding is wound in the same direction (ie preferably from the front 12 towards the rear or alternatively from the rear towards the front 12) with a winding diameter D substantially equal to one turn to the other.
- the predetermined number of turns and/or the spacing pitch of said turns for example four turns for the first configuration 32, and seven turns for the second configuration 34, is predetermined as a function of the heat density necessary for defrosting.
- said overlapped turns are contiguous on the first centimeter of winding near the open end 12, and in the number of ten contiguous turns.
- the predetermined number of turns and/or the spacing pitch of said turns is in particular obtained by means of thermal calculations as a function of the heating density (i.e. heat) necessary near the open end 12 and for the measurement mission considered. , to protect any measurement from being distorted by icing.
- the heating density i.e. heat
- the spacing pitch is such that said turns overlapped by said bridge are contiguous, which makes it possible to maximize the heating density near the open end 12 of the tube 10, the most critical zone to defrost in particular to prevent frost from distorting the measurement carried out using said measuring equipment.
- said overlapped turns are contiguous on the first centimeter of winding near the open end 12.
- said bridge P is external by being located on the turns, contiguous in the example of Figure 4, in a radial direction going from the inside to the outside of said tube 10 (i.e. the term "external » meaning in said radial direction going from the inside to the outside of said tube 10).
- the associated shaping method comprises a first step of forming the contiguous part of the heating wire turns, then a second step of forming the point P external above said contiguous turns, then a third step of shaping the non-contiguous part of the heating wire.
- the measuring equipment when, as illustrated by Figure 1, is a Pitot probe or a Pitot-static probe, such equipment has within the tube 10 a groove configured to accommodate said bridge P.
- the groove suitable for housing the external bridge of the first configuration 32 is not shown although it would be provided in the tube of the Total 16 of Figure 1 to accommodate the external bridge P according to said first configuration 32.
- said bridge P is internal by being located under the turns, contiguous in the example of Figure 4, in a radial direction going from the inside to the outside of said tube 10 (ie the term "internal » meaning in said radial direction going from the inside to the outside of said tube 10).
- the measuring equipment is a Pitot probe or a Pitot-static probe
- said tube 10 corresponding to a Pitot tube
- said Pitot tube comprising furthermore an internal tube 14 as illustrated in Figures 1 and 4
- such equipment has within the tube 10, and at the level of said internal tube 14, a groove 38 configured to accommodate said bridge P.
- the associated shaping method comprises a first step of preforming the internal bridge P, a second step of inserting said internal bridge P into said dedicated groove 38 of the internal tube 14 , then a third step of forming the contiguous part of the turns of the heating wire, as illustrated according to the example of Figure 4, then a fourth step of forming the non-contiguous part of the turns of the heating wire.
- the bridged winding comprises, according to the embodiment illustrated in Figure 4, both a non-joining part and a joining part overlapped by said bridge.
- these assemblies are held in position by strong soldering, all of the cavities and intersections of the part being filled with solder.
- such heating assemblies with bridged windings benefit in particular from the evolution of the parts around the winding. Indeed, in the latest probe designs, such parts, namely the internal tubes 14 and Total tubes 16 tend to be increasingly thick, and the present invention takes advantage of this extra thickness of material to accommodate other functions, such as the bridged winding proposed here, the housing grooves optionally proposed in addition to accommodate the winding bridge P being suitable for being integrated (i.e. housing) within such an extra thickness of the internal tube 14 for configuration 34 of bridged winding with internal bridge, and the Totale 16 tube for configuration 32 of bridged winding with external bridge.
- This bridge allows, independently of configuration 32 or 34, to obtain a “return” winding almost in “single thickness” of heating wire.
- the very thin “double thickness” surface is certainly capable of generating thermal loss, but negligible, especially considering the fact that embedding the bridge P in a groove 38 of the internal tube 14 or the Total 16 (ie external tube 16) allows you to recover the calories of this portion of the heating wire bridge for heating the areas to be defrosted.
- winding at the end may have a contiguous turn or not, depending on the heat density required in this area.
- the present invention through the proposed bridged winding, and illustrated in Figure 4, makes it possible to retain all the advantages of the “round trip” winding of the state of the art previously illustrated in Figure 3, while avoiding the The bulk and loss of efficiency associated with the implementation of a double thickness over the entire “round trip” of the winding.
- the present invention makes it possible to get rid of the double thickness which takes up more space and which causes heat dissipation difficulties.
- the bridged winding proposed according to the present invention makes it possible to bring the greatest possible density of heating wire to the front of the measuring equipment, without the empty spaces associated according to the state of the art with a pinned winding.
- the present invention makes it possible in particular to significantly improve the defrosting performance of Pitot or Pitot-static probes in supercooled water, particularly in the most critical zone: the front end of such Pitot or Pitot-static probes, without however impacting the duration of life of the wire due to overheating in less severe conditions, particularly on the ground or in the event of high altitude dry air flight.
