Description
Dispositif à poche d'eau permettant le largage par helicopt-ère bombardier d'eau,de nuit,en toute sécurité et avex précision. Water bag device allowing the release by water bomber helicopter, at night, in complete safety and with precision.
Classiquement les hélicoptères bombardiers d'eau ne amont pas utilisés la nuit car l'approche- suffisante -des- foyer; d'incendie n'est pas possible en toute sécurité par manque de visibilité.Le largage d'eau à trop haute altitude étant imprécis par dispersion excessive de l'eau et sa déviation par le vent. Conventionally, water bomber helicopters are not used upstream at night because the approach is sufficient for the home; Fire is not possible safely due to lack of visibility. Dropping water at too high an altitude is imprecise by excessive dispersion of water and its deflection by the wind.
Le dispositif selon l'invention permet de remédier à ces inconvenients et de ne plus observer la si défavorable torve nocturne. The device according to the invention makes it possible to remedy these drawbacks and to no longer observe the unfavorable night torve.
sL'eau est contenue dans une poche en toile ou en matière plastique,elle même contenue dans une poche en toile trés forte fermée en bas par un verrou électro-magnétique.Une série de rubans autocollants centrés par une substance exploslveJ en trés petite quantité quadrillent l'extérieur de la poche interne et sont reliés-à un dispositif de mise à feu classique situé sur le haut de la poche,avec détonateur et pile.Une larr:2Ie en matière plastique isolante est intercalée entre deux lamelles en cuivre et empêche ainsi la fermeture du circuit de mise à feu.Cette lamelle est reliée à un fil de mise à feu de longueur donnée aboutissant,en haut,à la cabine de pilotage où il est attaché. sWater is contained in a canvas or plastic pocket, itself contained in a very strong canvas pocket closed at the bottom by an electro-magnetic lock. A series of self-adhesive tapes centered by an explosive substance in very small quantities the outside of the internal pocket and are connected to a conventional firing device located on the top of the pocket, with detonator and battery. A larr: 2Ie made of insulating plastic material is interposed between two copper strips and thus prevents the closing of the firing circuit. This strip is connected to a firing wire of given length leading, at the top, to the cockpit where it is attached.
La poche d'eau est contenue dans la poche en toile trés forte qui est suspendue,par un cable d'acier de quelques métres,au train de l'hélicoptère par un crochet adapté à un site d'accrochage.Entre les deux poches est étalé un lubrifiant.La mise en place du crochet établit en même temps un contact jlectrique permettant au pilote de commander l'ouverture du fond de la poche externe par déverrouillage du mécanisme électromagnétique classique. The water pocket is contained in the very strong canvas pocket which is suspended, by a steel cable of a few meters, from the helicopter train by a hook adapted to a hanging site. Between the two pockets is spreading a lubricant. The installation of the hook simultaneously establishes an electrical contact allowing the pilot to control the opening of the bottom of the external pocket by unlocking the conventional electromagnetic mechanism.
Une fois l'eau larguée avec la poche interne la ptl externe et son cable suspenseur sont contractés par un extensetar qui était tendu.Ils ne constituent donc pas un danger pour pâles de l'hélicoptère.Au retour de l'appareil une nouvelle poche interne est mise en place dans la poche externe qui est reverrouillée. Once the water has been released with the internal pocket, the external ptl and its suspending cable are contracted by an extensetar which was stretched. They therefore do not constitute a danger for the pale of the helicopter. is placed in the outer pocket which is locked.
Le pilote vient,de nuit,et se place à assez haute altitude à la verticale du foyerd'incendie.Par pression sur un bouton il déverrouille le mécanisme électromagnétique.La poche d'eau interne descend aussitôt(lubrifiant).Une fois le fil de mise à feu tendu il arrache la lamelle en matière plastique qui laisse se toucher les deux lamelles en cuivre,d'où mise à feu et explosion des rubans autocollants qui découpent Za poche en lambeaux carrés.Sous l'effet de la résistance de l'air l'eau s'étale alors. The pilot comes at night and places himself at a fairly high altitude above the fire pit. At the press of a button, he unlocks the electromagnetic mechanism. The internal water pocket goes down immediately (lubricant). stretched firing it tears off the plastic strip which lets the two copper strips touch, where ignition and explosion of the self-adhesive tapes which cut the pocket into square rags. Under the effect of the resistance of air the water then spreads.
En réglant la longueur du fil de mise à feu,pour une altitude donnée,on règle l'altitude à laquelle la poche "explose'iet laisse l'eau s'étaler. By adjusting the length of the ignition wire, for a given altitude, you adjust the altitude at which the pocket "explodes' and lets the water spread.
Dans une autre-forme de réalisation le fil de mise à feu est enroulé autour d'une poulie blocable par un frein electro-mécanique commandé par le pilote qui choisit ainsi l'altitude"d'éxplosion"de la poche interne qu'il vient de larguer. In another embodiment, the ignition wire is wound around a block pulley by an electro-mechanical brake controlled by the pilot who thus chooses the altitude "of explosion" of the internal pocket that he comes to drop.
L'eau descend à la verticale,groupée dans sa poche, comme une bombe,emmagasinant une énorme énergie cinétique puis, dès-"l'explosion" des rubans autocollants,elle s'etale sur une surface dépendant de l'altitude de l'explosion(homothetiej.La force du choc sur le sol,et partant la force et l'ampleur de l'étalennent horizontal qui s'en suit,sont sans commune mestre avec l'arrosage classique. The water descends vertically, grouped in its pocket, like a bomb, storing an enormous kinetic energy then, as soon as "the explosion" of the self-adhesive tapes, it spreads out on a surface depending on the altitude of the explosion (homothetiej. The force of the shock on the ground, and consequently the force and the extent of the horizontal spread which follows, are without common master with the classic watering.
Dans une autre forme de réalisation le frein électro ågWnétique est commandé,par liaison radio à partir du sol,car un officier peut choisir ainsi l'altitude "d'explosion"de la poche en fonction de l'évolution du feu.Pour être visible de nuit la poche est réflectorisée et éclairée par un projecteur fixé à l'hélicoptère. In another embodiment the ågWnétique electro brake is controlled, by radio link from the ground, because an officer can thus choose the "explosion" altitude of the pocket according to the evolution of the fire. at night the pocket is reflectorized and lit by a searchlight attached to the helicopter.
Dans une autre forme de réalisation,à réglage de l'altitude de "l'explosion" indépendant de l'altitude de l'hélicoptère un contacteur au choc,sufisamment lesté,est gIspendu à la-poche d'veau qu'il précède dans la descente.Lx longueur de son fil suspenseur est égale à l'altitude choisie four 2'1'explosion".Ce qui permet le réglage.Le dispositif de mise a feu est ici en position inférieure. In another embodiment, with adjustment of the altitude of the "explosion" independent of the altitude of the helicopter, an impact contactor, sufficiently ballasted, is suspended from the calf pocket which it precedes in the descent. The length of its suspension wire is equal to the altitude chosen for the oven 2'1'explosion ". This allows adjustment. The firing device is here in the lower position.
Ainsi le largage d'eau de nuit devient,non seulement possible,en toute sécurité,mais encore plus précis que le largage de jour.Ceci comme dans le bombardement militaire de nuit d'une cible éclairée.D'ailleurs les organes de visée sont parfaitement utilisables ici,de même que le balivage radio au sol et le-radio-guidage.Navigation et largage peuvent être orchestrés par un ordinateur où sont rentrées les données de l'observation aerienne. Thus, the release of water at night becomes not only possible in complete safety, but even more precise than the release by day. This is as in the military bombardment of a lighted target at night. perfectly usable here, as well as radio tracking on the ground and radio-guidance. Navigation and dropping can be orchestrated by a computer where the data from the aerial observation are entered.
Le dispositif selon l'invention,utilisable de nuit, l'est à plus forte raison de jour,et permet alors déviter,par une altitude de1argage plus grande,les inconvénients de la chaleur,de la fumée et des risques d'accidents liés aus interventions à basse altitude.Le pilote choisira le juste visée et la milieu entre la trop grande altitude préjudiciable à la asse altitude et ses dangers. The device according to the invention, which can be used at night, is even more effective during the day, and thus makes it possible to avoid, by a greater release altitude, the drawbacks of heat, smoke and the risks of accidents linked to interventions at low altitude. The pilot will choose the right target and the middle between the too high altitude detrimental to the enough altitude and its dangers.
