The water is contained in a bag (1), made of sufficiently strong material, suspended from the helicopter. The bottom of this bag is equipped with a self-adhesive cross shape (16) including a thin border of explosive substance which will cut the bag and let the mass of water fall when the pilot triggers the explosion by means of a small control box in his possession.

Description

Système modulaire selon l'invention adaptant instantanément tout hélicoptère standart à la lutte contre les incendies de forêts selon le mode "CANADAIR". Modular system according to the invention instantly adapting any standard helicopter to the fight against forest fires according to the "CANADAIR" mode.

Contre les incendies de forêts entamant gravement le patrimoine forestier en période estivale de nombreux moyens de lutte sont utilisés parmi lesquels les hélicoptères canadairs" occupent une place de choix,surtout grâce aux facilités d'accés et à la rapidité propres aux moyens aériens.Mais la demande se fait le plus souvent selon un mode paroxystique.Les appareils, fort coûteux, sont rarement en nombre suffisant. Numerous means of control are used against forest fires which seriously damage the forest heritage in the summer, among which Canadian helicopters "occupy a special place, especially thanks to the ease of access and the speed specific to aerial means. demand is most often made in a paroxysmal mode. The devices, very expensive, are rarely in sufficient number.

Le but du système- selon l'invention est de permettre l'utilisation immédiate,selon le modecanadair;de tous les hélicoptères civils et militaires contre les incendies de forêts. The purpose of the system according to the invention is to allow the immediate use, according to the modecanadair, of all civil and military helicopters against forest fires.

Ceci sans transformation notable.This without significant transformation.

Selon le mode de réalisation préféré l'eau,ou tout autre liquide utilisé,est contenue dans une poche en toile suffisamment forte.Cette poche,en forme de boudin cylindrique est fermée sur le haut,comme une bourse,par une pièce métallique reliée à un cable d'acier se terminant par un crochet s'adaptant au train de l'hélicoptère avec verrouillage interdisant tout décrochage intempestif.*Le fond de la poche est circulaire,fait d'une pièce indépendante solidement cousue au reste de la poche. According to the preferred embodiment, the water, or any other liquid used, is contained in a sufficiently strong canvas pocket. This pocket, in the form of a cylindrical rod, is closed at the top, like a purse, by a metal piece connected to a steel cable ending in a hook adapting to the train of the helicopter with locking preventing any untimely stalling. * The bottom of the pocket is circular, made of an independent piece securely sewn to the rest of the pocket.

Sur ce fond est fixé un aut ocoll ant--;crucif orme dont chaque partie est égale au diamétre du fond.Les branches de l'autocollant sont centrées par un fin liseré de substance explosive,en quantité trés minime,juste suffisante pour découper a coup sûr la toile déjà trés tendue.Ce découpage interesse donc tout le fond afin de permettre une descente,massive et assez brusque de liteau, évitant ainsi toute turbulence préjudiciable à la stabilité de l'hélicoptère.La substance explosive de l'autocollant est reliée à la cabine de pilotage par un cable bifilaire aboûtissant à un boitier de commande,avec pile et contacteur,en possession du pilote qui peut ainsi commander le lâchage del'eau.La liaison électrique entre la poche de liquide et leboitier peut se faire de manière classique par des contacts électriques situés au niveau du site d'accrochage du cable porteur.Ainsi accrochage de la poche et liaison électrique se font concomittament.On this bottom is fixed an aut ocoll ant -; cruciform elm of which each part is equal to the diameter of the bottom. The branches of the sticker are centered by a fine border of explosive substance, in very minimal quantity, just sufficient to cut a sure the canvas already very stretched.This cutting therefore interested the whole bottom to allow a descent, massive and fairly sudden batten, thus avoiding any turbulence detrimental to the stability of the helicopter.The explosive substance of the sticker is connected to the cockpit by a bewildering two-wire cable to a control box, with battery and contactor, in the possession of the pilot who can thus control the release of the water. The electrical connection between the liquid bag and the case can be done in such a way conventional by electrical contacts located at the site of attachment of the carrying cable. Thus attachment of the pocket and electrical connection are concomitant.

Le pilote,en étahlissant le contact grâce au boiter de commande,précipite la masse d'eau sur le foyer.d'incendie qu'il aura choisi d'attaquer(dispositif de mise à feu électrique). The pilot, by making contact with the control unit, precipitates the mass of water on the fire hearth. He will have chosen to attack (electric firing device).

Il est à remarquer que ce système peut permettre le lachâge de quantités trés considérables d'eau selon la puissance de l'hélicoptère utilisé.Le mode de pilota sera adapté à ce type de mission afin de bien contrôler la poche sur le plan balancement et rotation notamment.Cette tâche peut être assimilée aux transports de vehicules,parfois trés lourds par des hélicoptères militaires.A tout moment le pilotepeut se débarasser de a charge s'il l'estime nécessaire. It should be noted that this system can allow the release of very considerable amounts of water depending on the power of the helicopter used. The pilota mode will be adapted to this type of mission in order to properly control the pocket in terms of swing and rotation This task can be assimilated to the transport of vehicles, sometimes very heavy by military helicopters. At any time the pilot can get rid of the load if he considers it necessary.

Une fois la masse d'eau lâchée sur le foyer d'incendie l'hélicoptère revient à son point de départ.La poche est remplacée par une poche pleine déjà prête,avec son cable et son crochet. Once the body of water is released onto the fire, the helicopter returns to its starting point. The pocket is replaced by a full pocket already ready, with its cable and its hook.

lthélicoptère repart immédiatement et ne sera resté que quelques dizaines de secondes à la base. the helicopter leaves immediately and will only have stayed at the base for a few tens of seconds.

La poche creuvée et vide sera réutilisable aprés emplacement de son fond et fixation d'un nouvel autocollant
elié au cable électrique bifilaire.Le fond peut être modulaire t bord métallique interchangeable).The empty and empty pocket will be reusable after placing its bottom and attaching a new sticker
connected to the two-wire electric cable. The bottom can be modular t interchangeable metal edge).

I1 est à remarquer que ce système peut permettre une rotation trés rapide d'hélicoptères qui,à l'origine,ntétaient pas déstinés à la lutte contre l'incendie.Il suffit de prévoir des pôches prêtes à l'emploi.Le dispositif peut être encore plus performant,si,dès le repèrage d'un départ de feu important ou risquant de le devenir rapidement,des pôches sont rapprochées, autant que le permettent les voies de communication routières ou ferroviaires.Ainsi par exemple un incendie noyé dans une trés grande et épaisse forêt peut être rapidement pris de vitesse s'il est situé à quelques kilomètres d'une voie ferrée seule à traverser cette forêt.Le train spécial s'arrete à proximité et alimente en pôches les hélicoptères.S'il s'agit d'hélicoptères lourds,porteurs de solides et grandes poches deversées à rythme soutenu le résultat sera rapide et spectaculaire(l'eau de mer peut également être utilisée).

Figure img00020001
It should be noted that this system can allow very rapid rotation of helicopters which were not originally intended for fire fighting. It is sufficient to provide ready-to-use sockets. even more efficient if, as soon as a large fire starts or is likely to become quickly spotted, pockets are brought together, as far as road or rail communication channels allow, for example a fire drowned in a very large and thick forest can be quickly overtaken if it is located a few kilometers from a railway track alone to cross this forest. The special train stops nearby and supplies the helicopters with poaching. 'heavy helicopters, solid carriers and large pockets poured at a sustained rate the result will be rapid and spectacular (sea water can also be used).
Figure img00020001

Les hélicoptères lourds peuventvutilisés comme "canadairs" mais aussi comme livreurs de poches toutes protes avec leurs cables.Ainsi,des le début de la grande alerte pour une roret sans voie de communication aucune,les hélicoptères lourds déposent dans une clairière avoisinnante un lôt de poches, de contenance étudiée,que des appareils non spécialisés,moins gros et plus nombreux viennent chercher et vider,avec une plus brande sélectivité,sur le foyer d'incendie proche,ceci avec un rythme de rotation si rapide que le feux est pris de vitesse. Heavy helicopters can be used as "canadairs" but also as pocket deliverers very protected with their cables. Thus, from the beginning of the great alert for a whale without any communication channel, heavy helicopters deposit in a glade neighboring pockets , of studied capacity, that non-specialized devices, smaller and more numerous come to seek and empty, with a greater selectivity, on the near fire hearth, this with a rate of rotation so fast that the fires are taken speed .

Le système selon l'invention est également applicable. The system according to the invention is also applicable.

en cas d'urgence,à l'alimentation en eau-des équipes terrestres de sapeurs pompiers ou à l'alimentation(pôches spéciales)de popu lations sinistrées.in the event of an emergency, supplying water to land-based teams of firefighters or supplying (special fishing bags) to disaster-stricken populations.

A noter la possibilité d'appliquer ce système à des ultra légers motorisés(ULM)contre des foyers d'incendies petits et résiduels mais néanmoins potentielement trés dangereux. Note the possibility of applying this system to motorized ultra-light (ULM) against small and residual fires, but nevertheless potentially very dangerous.

Le système peut utiliser des poches en matière plastiqUe assez résistante ou des fûts métalliques à ouverture par dispositif electro-mécanique.  The system can use bags of fairly resistant plastic material or metal drums open by electro-mechanical device.

Ce système ne nécessite pas de transformations notables au niveau des hélicoptères.Tout juste un site d'accrochage judicieusement situé.Outre son aspect économiqueoil permet notamment l'utilisation de trés puissants hélicoptères militaires dans la lutte contre les incendies de forêts.Ce système est par ailleurs parfaitement utilisable contre des incendies urbains. This system does not require any significant modifications to the level of the helicopters. Just a conveniently located hanging site. In addition to its economic aspect, it notably allows the use of very powerful military helicopters in the fight against forest fires. elsewhere perfectly usable against urban fires.
