Abstract
The ejectable tanks are fuel tanks with less fuel capacity, compare to the ones used actually, they can be launched from the airplane in case of an emergency to prevent fire or explosion, without loosing the full capacity of fuel.
Description
Tanques Eyectables para Aviones Ejectable Tanks for Aircraft
Se trata de tanques de combustible de una aeronave que pueden ser lanzados, ante Ia inminencia de una emergencia que pudiera dar lugar a un incendio.These are fuel tanks of an aircraft that can be launched, before the imminence of an emergency that could lead to a fire.
La idea se basa en que no pueden lanzarse simultáneamente los tanques de combustible regulares de una aeronave, ya que eso obligaría a que grandes compuertas se abrieran para botarlos, Io cual probablemente seria difícil y ademas podría hacer perder Ia capacidad de sustentación, que aunque fuera momentáneamente, sería riesgoso.The idea is based on the fact that the regular fuel tanks of an aircraft can not be launched simultaneously, since this would force large gates to open to throw them out, which would probably be difficult and could also cause the capacity to be lost, although momentarily, it would be risky.
Para evitar Ia pérdida de sustentación al botar los tanques, se ha considerado que Io adecuado es, que en lugar de unos pocos tanques grandes, Ia aeronave sea provista de un mayor número de tanques menores, que van montados sobre carriles donde pueden deslizarse, unidos uno al otro por cables y salir todos por una sola compuerta que no afecta Ia capacidad de sustentación. Los tanques deberán estar unidos uno al otro, por medio de cables, que les permitan salir uno a Ia vez.To avoid the loss of lift when the tanks are thrown away, it has been considered appropriate, that instead of a few large tanks, the aircraft is provided with a greater number of smaller tanks, which are mounted on rails where they can slide, united one to the other by cables and to leave all by a single gate that does not affect the capacity of sustentation. The tanks must be joined to each other, by means of cables, which allow them to leave one at a time.
El largo de los cables que unen los tanques, debe ser calculado para que en todo momento se cuente con Ia fuerza, ejercida por el peso del o de los que ya han salido y sea suficiente para jalar y sacar a los que quedan o pendientes de salir. Si Ia emergencia ocurriera sobre un área poblada se puede dotar con un paracaidas al ultimo tanque.The length of the cables that join the tanks must be calculated so that at all times there is strength, exerted by the weight of the one or those that have left and it is enough to pull and remove those who are left or pending. go out. If the emergency occurs over a populated area, the last tank can be equipped with a parachute.
Este sistema puede funcionar también cuando los tanques están instalados en el fuselaje o en cualquier otro lugar de Ia aeronave.This system can also work when the tanks are installed in the fuselage or in any other place of the aircraft.
La salida de los tanques debe ser con curva, como de resbaladero pequeño, para facilitar Ia fuerza que ejerce el cable y para facilitar Ia salida de los tanques.The exit of the tanks must be curved, as a small slide, to facilitate the force exerted by the cable and to facilitate the exit of the tanks.
Los tanques deben estar asegurados, como seguros que se desenganchen antes de lanzarlos, con Ia finalidad de que no se corran de posición mientras no haya eyección.The tanks must be secured, as they are sure to unhook before releasing them, so that they do not run out of position while there is no ejection.
Las mangueras o- conductos de entrada y salida o cualquier otro deben de estar orientados y provistos de acoplamientos de manera que se desprendan ante fuerza de tensión, producida al comenzar a salir. Estos acoplamientos deberán tener válvulas que se cierren al desacoplarse para evitar derramamientos, tanto en los depósitos como en las mangeras o conductos.The hoses o-conduits of entrance and exit or any other must be oriented and provided with couplings in such a way that they come off before tension force, produced when starting to leave. These couplings must have valves that close when uncoupling to avoid spills, both in the tanks and in the hoses or ducts.
En casos que se considere prudente podría considerarse que no se eyectaran Ia totalidad de los tanques, quedando solo los necesarios para volar un tiempo prudencial a criterio del piloto, para ser lanzados hasta en último momento.
In cases considered prudent, it could be considered that not all the tanks were ejected, leaving only those necessary to fly a prudential time at the pilot's discretion, to be launched until the last moment.
Claims
REIVINDICACIONES
1) Los Tanques Eyectables a diferencia de los usados actualmente, son menor de capacidad.1) The Ejectable Tanks, unlike those currently used, are smaller in capacity.
2) Pueden ser lanzados de Ia aereonave en caso de emergencia, evitando un incendio o explosión.2) They can be thrown out of the aircraft in case of emergency, avoiding a fire or explosion.
3) Van unidos por un cable y montados en un conducto curvo donde pueden deslizarse y salir todos por una sola compuerta uno a Ia vez.3) They are joined by a cable and mounted in a curved duct where they can slide and exit all through a single gate one at a time.
4) A Ia hora de ser lanzados no se pierde Ia capacidad total de combustible.4) At the time of being launched, the total fuel capacity is not lost.
5) Pueden ir instalados en las alas, fuselaje o en cualquier otro lugar de Ia aereonave.
5) They can be installed on the wings, fuselage or any other place in the aircraft.
