La présente invention concerne les procédés et dispositifs de dégivrage des aéronefs au sol, et plus généralement de dégivrage ou réchauffage de véhicules, d'appareils ou de sites de grandes dimensions. The present invention relates to methods and devices for de-icing aircraft on the ground, and more generally for de-icing or reheating vehicles, devices or large sites.
Pour dégivrer les parties courantes des aéronefs, et plus particulièrement les ailes et les carlingues, on a généralement recours à des procédés de projection d'eau pulvérisée réchauffée additionnée de produits dégivrants. To defrost the main parts of aircraft, and more particularly the wings and cabins, recourse is generally had to spraying sprayed water with added deicing agents.
Ces dispositifs procèdent au dégivrage par traitement localisé et balayage des surfaces. These devices defrost by localized treatment and sweeping of the surfaces.
Ils sont relativement lents et immobilisent longtemps les appareils au sol, ce qui a pour conséquence d'engorger les aéroports en période hivernale. They are relatively slow and immobilize aircraft for a long time on the ground, which has the effect of clogging airports in winter.
Ils présentent l'inconvénient d'utiliser des produits chimiques en quantités, produits plus ou moins nuisibles pour l'environnement, et qui se répandent ultérieurement dans l'atmosphère et dans le sol. They have the drawback of using chemicals in quantities, products which are more or less harmful to the environment, and which subsequently spread in the atmosphere and in the soil.
De plus ils ne sont pas applicables en temps masqué au terminal d'embarquement, mais sont mis en oeuvre dans des stations spéciales au sein des aéroports. In addition, they are not applicable in masked time at the boarding terminal, but are implemented in special stations at airports.
On connaît par ailleurs les cassettes ou appareils de chauffage par rayonnement infra rouge plans basse température, comme par exemple ceux décrits dans le brevet d'invention français N' 01 04941. Ces appareils peuvent être constitués d'émetteurs fabriqués à partir de films conducteurs à très faible inertie thermique, ou bien d'émetteurs plus épais, par exemple en verre trempé avec couche résistive déposée sous 20 vide, permettant d'émettre un flux infrarouge homogène dans une certaine direction. Cassettes or apparatuses for heating by infrared radiation at low temperature planes are also known, such as for example those described in the French invention patent No. 01 04941. These apparatuses may consist of emitters made from conductive films with very low thermal inertia, or else thicker emitters, for example made of tempered glass with a resistive layer deposited under vacuum, making it possible to emit a homogeneous infrared flux in a certain direction.
Ces panneaux radiants basse température, c'est à dire fonctionnant en dessous de 200'C sont particulièrement intéressants pour l'application envisagée. En effet, les panneaux infra rouge classiques fonctionnent généralement à des températures supérieures à 210 'C, qui est le seuil d'inflammabilité du Kérosène: leur emploi présente donc un 25 danger certain pour traiter des aéronefs. Par contre, les panneaux fonctionnant en dessous de la température d'auto inflammation du Kérosène offrent une sécurité d'emploi sur un site de présence potentielle de Kérosène. These low temperature radiant panels, that is to say operating below 200 ° C. are particularly advantageous for the envisaged application. Indeed, conventional infrared panels generally operate at temperatures above 210 ° C., which is the flammability threshold for kerosene: their use therefore presents a certain danger for treating aircraft. On the other hand, the panels operating below the auto-ignition temperature of the Kerosene offer security of use on a site of potential presence of Kerosene.
Le problème posé par la présente invention est de concevoir de nouveaux équipements qui permettraient de procéder au dégivrage des aéronefs dans des conditions de sécurité, à sec et plus rapidement qu'aujourd'hui, sans utiliser de produits chimiques, et en agissant globalement par procédés surfaciques sur les parties à traiter, les ailes, ou la carlingue des aéronefs, procédé propre qui pourrait être mis en oeuvre en temps masqué à un terminal ordinaire sur un appareil en cours de chargement ou d'embarquement sans nécessiter de passage à une station de dégivrage spécifique. The problem posed by the present invention is to design new equipment which would allow aircraft to be de-iced under safe conditions, dry and faster than today, without using chemicals, and acting globally by processes. surfaces on the parts to be treated, the wings, or the cabin of aircraft, a clean process which could be implemented in masked time at an ordinary terminal on a device being loaded or loaded without requiring passage to a station specific defrost.
La solution technique proposée utilise un ensemble de panneaux légers radiants infra rouge formant une surface globale radiante que l'on vient positionner en vis à vis immédiat des surfaces à dégivrer. Cet ensemble de panneaux peut constituer un plan ou une vote pouvant être dimensionné sensiblement selon les dimensions globales des ailes à dégivrer, ou bien selon une portion des ailes si l'on envisage de traiter en plusieurs portions. Il peut constituer une portion de cylindre selon que l'on veuille traiter la partie supérieure d'une carlingue. The technical solution proposed uses a set of light infrared radiant panels forming a global radiant surface which is positioned immediately opposite the surfaces to be defrosted. This set of panels can constitute a plan or a vote which can be dimensioned substantially according to the overall dimensions of the wings to be defrosted, or else according to a portion of the wings if it is envisaged to treat in several portions. It can constitute a portion of cylinder according to whether one wants to treat the upper part of a cabin.
La figure 1 montre en coupe un dispositif de dégivrage d'ailes d'aéronefs selon l'invention. Figure 1 shows in section a device for deicing aircraft wings according to the invention.
La figure 2 montre de face un dispositif de dégivrage de carlingues selon l'invention. Figure 2 shows a front view of a cabin defrosting device according to the invention.
La figure 3 montre un dispositif modulaire de dégivrage d'ailes d'aéronefs selon l'invention, représenté sur le plan schématique d'un aéronef coupé selon son axe de 15 symétrie. FIG. 3 shows a modular device for deicing aircraft wings according to the invention, represented on the schematic plan of an aircraft cut along its axis of symmetry.
La figure 4 montre en coupe un véhicule de dégivrage de chaussée selon l'invention. Figure 4 shows in section a road defrosting vehicle according to the invention.
Dans un mode de réalisation illustré par la figure 1, on réalise un tunnel de dégivrage mobile (1) à l'aide d'un ensemble de panneaux légers radiants infra rouge (2) basse température. La surface globale ainsi constituée rayonne dans l'infra rouge. Le tunnel 20 (1) peut être avantageusement en forme de vote. In an embodiment illustrated in FIG. 1, a mobile defrost tunnel (1) is produced using a set of light infrared radiant panels (2) at low temperature. The overall surface thus formed radiates in the infrared. The tunnel 20 (1) can advantageously be in the form of a vote.
Les panneaux radiants deviennent émetteurs infra rouge lorsqu'ils sont parcourus par du courant électrique. Ce courant peut être amené soit par un réseau extérieur, soit par un générateur autonome spécifique. The radiant panels become infrared emitters when they are traversed by electric current. This current can be brought either by an external network, or by a specific autonomous generator.
Le tunnel mobile (1) est approché au dessus de la surface à traiter de l'aile (3) et vient 25 former un espace confiné (4) entre l'aile et la vote. Dans cet espace, la surface de l'aile à dégivrer (3) se trouve directement en regard de la vote radiante (1) . Une jupe souple (12) vient compléter la fermeture de l'espace confiné (4) en s'adaptant à la forme de l'appareil à traiter. The mobile tunnel (1) is approached above the surface to be treated of the wing (3) and comes to form a confined space (4) between the wing and the vote. In this space, the surface of the wing to be defrosted (3) is directly opposite the radiant vote (1). A flexible skirt (12) completes the closure of the confined space (4) by adapting to the shape of the device to be treated.
Lorsque l'on met sous tension électrique les éléments radiants (2) du tunnel mobile (1), il se produit dans l'espace confiné (4) un micro climat chaud et sec, dans lequel la glace disparaît rapidement par sublimation ou fusion/évaporation. When the radiant elements (2) of the mobile tunnel (1) are energized, a hot and dry micro-climate occurs in the confined space (4), in which the ice quickly disappears by sublimation or fusion / evaporation.
On peut optionnellement récupérer l'air chaud qui va se former au dessus de la vote (1) par un caisson ventilé (10) afin d'en balayer la surface à dégivrer (3) et d'accélérer le processus. One can optionally recover the hot air which will form above the vote (1) by a ventilated box (10) in order to sweep the surface to be defrosted (3) and to speed up the process.
Une fois que les surfaces ont été séchées par le dispositif, on peut compléter le traitement par une pulvérisation mesurée d'un produit abaissant la température de congélation. Once the surfaces have been dried by the device, the treatment can be completed by a measured spray of a product which lowers the freezing temperature.
La structure (5) maintient le tunnel(l) dans sa forme. The structure (5) maintains the tunnel (l) in its shape.
Le dispositif peut être monté sur un chariot (6) pour permettre un accès et une approche aisée de l'appareil ou du site à traiter. The device can be mounted on a trolley (6) to allow easy access and approach to the device or the site to be treated.
La structure (5) peut être de forme fixe, ou bien de forme adaptable selon le cas par un système d'articulation. The structure (5) can be of fixed form, or alternatively of form adaptable as the case may be by an articulation system.
Dans un mode de réalisation illustré par la figure 2, on réalise un tunnel de dégivrage (1) similaire à celui de la figure 1 pour traiter une carlingue (7). In an embodiment illustrated in FIG. 2, a defrost tunnel (1) similar to that of FIG. 1 is produced to treat a cabin (7).
Dans un mode de réalisation selon la figure 3, on réalise un dispositif composé de plusieurs éléments modulaires(l 1) selon l'invention qui, disposés côte à côte, viennent former un tunnel complet ou partiel dont la forme est adaptée à l'appareil ou la surface 20 à traiter (3). In an embodiment according to Figure 3, there is provided a device composed of several modular elements (l 1) according to the invention which, arranged side by side, come to form a complete or partial tunnel whose shape is adapted to the device or the surface 20 to be treated (3).
Dans un mode de réalisation selon la figure 4, on réalise un véhicule (8) disposant d'un tunnel (1) qui vient confiner un espace (4) au dessus d'une chaussée ou d'un trottoir (9) à dégivrer. In an embodiment according to FIG. 4, a vehicle (8) is produced which has a tunnel (1) which confines a space (4) above a roadway or a sidewalk (9) to be defrosted.
L'invention est susceptible d'applications industrielles dans le domaine des équipements de protection contre le gel et ses conséquences sur les aéronefs, les chaussées ou toute surface de grandes dimensions soumises à des températures basses. The invention is capable of industrial applications in the field of equipment for protection against frost and its consequences on aircraft, roadways or any large surface subjected to low temperatures.
La liste des applications n'est pas exhaustive, et l'on comprendra que l'homme de métier peut utiliser l'invention de diverses manières, profitant des avantages liés à la possibilité de constituer un micro climat chaud et sec au dessus de surfaces ou d'appareils de grandes dimensions soumis à des conditions de gel préjudiciables au bon fonctionnement ou à la sécurité, ou simplement nécessitant un réchauffage rapide. The list of applications is not exhaustive, and it will be understood that a person skilled in the art can use the invention in various ways, taking advantage of the advantages linked to the possibility of constituting a hot and dry micro-climate above surfaces or large devices subject to freezing conditions detrimental to their proper functioning or safety, or simply requiring rapid reheating.
La présente invention n'est pas limitée aux modes de réalisation qui ont été explicitement décrits, mais elle inclut les diverses variantes et généralisations contenues The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations contained
