Definitions
- the invention is concerned with the subject of the safe transport of a particularly insensitive ammunition (IM). It is envisaged to incorporate a type of ventilation concept (IM venting) into an ammunition box which will be activated when the ammunition box is exposed to a higher temperature and / or an internal pressure builds up which could lead to critical situations.
- IM venting a type of ventilation concept
- the boxes filled with ammunition are exposed by an external heat source - fire at Fast Cook-Of, heat at Slow Cook Of.
- the explosives are heated to the auto-ignition temperature, which can lead to reactions.
- the lid of the box can be blown off and / or ammunition parts can be thrown out.
- a container in particular for receiving ammunition, which comprises a so-called venting system.
- a fusible link between a lower flange and an upper flange is integrated with a sealing flange.
- the fusible material has a melting point below the ignition temperature of the ammunition. Depending on the application, this melting point is between 190 ° F and 270 ° F.
- the material proposed is synthetic material, preferably an ionomeric (thermoplastic) plastic reinforced with glass fibers, which has a melting point of about 250 ° F to about 270 ° F. If the ammunition container is subject to such a high temperature, the material melts and ensures a venting of the container.
- a cartridge ammunition is known, which is filled in channels with a fusible, solid and pressure-tight material whose melting temperature is lower than the ignition temperature of the pyrotechnic ignition device.
- the channels rejuvenate towards their exit, resulting in the firing of the ammunition high pressures are absorbed so that prevents the molten metal starts to flow and the channels are released.
- the cartridge is heated to the melting temperature of the melt material, the material melts. If the primer and thus the propellant charge are ignited at further increasing temperatures, no pressure can build up in the propellant chamber.
- the exposed passages act as pressure relief ports.
- the US 2003/0205161 A describes a projectile whose bottom is closed by a lid which is held in the projectile by an externally located locking ring made of a melting material. When the temperature rises, this sealing ring melts, so that the lid is released from the ground and an explosive ignition of the actual active charge is prevented.
- An ammunition box according to the preamble of the dependent claim 1 is known from DE 2 209 111 A known.
- the invention arises, starting from the DE 2 209 111 A , the task to show a Munitionsbox that realizes a safe transport for particular IM ammunition.
- the invention is based on the idea of incorporating a type of ventilation concept (IM - Venting) into a box itself, the ventilation concept then being put into action when the box is exposed to a higher temperature and / or an internal pressure builds up which leads to critical situations could.
- This may preferably be an already existing or known box, such as an ammunition box. If desired, the other properties of the box can be retained.
- Holes and / or openings in the wall of the crate are integrated into the crate at defined locations as exhaust openings for the integration of the venting system. These can be filled with a fusible material. This makes the box waterproof and dustproof. As a result, a retrofit is possible. Similar to the solution for insensitive ammunition, the exhaust openings are opened upon reaching a certain internal pressure or a critical temperature. The appropriate fusible material is turned off to the maximum allowable temperature. Through these openings, the internal pressure can escape.
- the openings or openings can also be closed with a defined thin-walled material or a plug.
- the plug or thin-walled material is pushed outward. Plug and material are in turn at the maximum in the box tuned internal pressure.
- a combination of both variants has the charm that temperature and internal pressure can be taken into account as parameters for the venting system.
- a closure opener is involved, which is driven by the venting system. This shutter opener is designed so that when the venting system is triggered on the front sides, the pressure is absorbed axially and the shutter of the box is opened.
- the venting system itself is designed so that neither the stability nor the environmental resistance of the box are adversely affected.
- the venting system also improves the IM properties of the ammunition itself in an ammunition box.
- Fig. 1, 1a show a box or box 1, here an ammunition box, with a cover 2, a venting system 3 in the ammunition box 1 and a box closure 4.
- holes / openings 5 are placed at defined locations in the box wall. These points are located laterally and / or in the lid 2 of the ammunition box 1. Holes or openings 5 can also be provided in the bottom area. These openings or holes 5 are closed with a (defined) thin-walled material or plug 6 ( Fig. 2 ). This ensures that the ammunition box 1 is waterproof and dirt-proof.
- the thin-walled material / plug 6 may itself be meltable. Alternatively, it is provided that this material / the plug 6 burst to release the holes 5.
- the venting system 3 is triggered.
- the increase in internal pressure can also be adjusted by increasing the temperature that may be subject to the ammunition box. In the case of a fusible material / plug 6, the increase in temperature leads to melting of the material / plug 6. This can also cause the venting system 3 to be triggered, the bores 5 to be released and the internal pressure to be reduced.
- a so-called closure opener 7 which can be triggered and / or driven by the venting system 3, in addition to the opening of the box 1 by hand.
- This shutter opener 7 is designed so that when the venting system 3 is triggered on the front sides, the pressure of the material and / or plug 6 or the internal pressure itself is absorbed axially, which is sufficient to open the closure 4 of the box 1.
- the closure 4 is pushed away from the box 1, the cover 2 can, here in the context of a closure bracket, give way.
- This lid 2 releases the opening of the box 1, which can open itself to a small degree.
- Such an arrangement shows the Fig. 3a in a plan view or Fig. 3b in a page presentation.
- the "defined" thin-walled material and the plug 6 are selected in terms of quantity so that they can be driven out of the holes by the influence of internal pressure.
- metallic alloys such as tin-bismuth, in which the melting temperature is about 138, are also suitable as the fusible material.
Description
Die Erfindung beschäftigt sich mit der Thematik des sicheren Transportes einer insbesondere insensitiven Munition (IM). Vorgesehen ist, eine Art Belüftungskonzept (IM-Venting) in eine Munitionskiste /-box einzubinden, das dann in Aktion tritt, wenn die Munitionskiste einer höheren Temperatur ausgesetzt ist und / oder sich ein Innendruck aufbaut, der zu kritischen Situationen führen könnte.The invention is concerned with the subject of the safe transport of a particularly insensitive ammunition (IM). It is envisaged to incorporate a type of ventilation concept (IM venting) into an ammunition box which will be activated when the ammunition box is exposed to a higher temperature and / or an internal pressure builds up which could lead to critical situations.
Bei IM - Tests werden die mit Munition gefüllten Kisten durch eine externe Wärmequelle - Feuer bei Fast Cook-Of, Hitze bei Slow Cook Of - ausgesetzt. Hierbei werden die Explosivstoffe bis zur Selbstentzündungstemperatur erhitzt, was zu Reaktionen führen kann. Sobald der Innendruck der Munitionskiste zu hoch ist, kann die Kiste Fragmente und Splitter bilden, der Deckel der Kiste abgesprengt und / oder Munitionsteile herausgeschleudert werden.In IM tests, the boxes filled with ammunition are exposed by an external heat source - fire at Fast Cook-Of, heat at Slow Cook Of. Here, the explosives are heated to the auto-ignition temperature, which can lead to reactions. As soon as the internal pressure of the ammunition box is too high, the box can form fragments and splinters, the lid of the box can be blown off and / or ammunition parts can be thrown out.

Der Erfindung liegt die Idee zugrunde, eine Art Belüftungskonzept (IM - Venting) in eine Kiste selbst einzubinden, wobei das Belüftungskonzept dann in Aktion tritt, wenn die Kiste einer höheren Temperatur ausgesetzt ist und / oder sich ein Innendruck aufbaut, der zu kritischen Situationen führen könnte. Dabei kann es sich vorzugsweise um eine bereits vorhandene bzw. bekannte Kiste, wie beispielswiese eine Munitionsbox, handeln. Wenn erwünscht, können die sonstigen Eigenschaften der Box beibehalten werden. In die Kiste werden an definierten Stellen Bohrungen und / oder Durchbrüche in der Kistenwandung als Ausblasöffnungen eingebunden zur Integration des Venting- Systems. Diese können mit einem schmelzbaren Material ausgefüllt sein. Dadurch ist die Kiste wasserdicht und staubgeschützt. Dadurch ist auch eine Nachrüstung möglich. Ähnlich der Lösung bei der insensitiven Munition werden bei Erreichen eines bestimmten Innendrucks oder einer kritischen Temperatur die Ausblasöffnungen geöffnet. Das entsprechende schmelzbare Material wird auf die maximal zulässige Temperatur abgestellt. Durch diese Öffnungen kann der Innendruck entweichen.The invention is based on the idea of incorporating a type of ventilation concept (IM - Venting) into a box itself, the ventilation concept then being put into action when the box is exposed to a higher temperature and / or an internal pressure builds up which leads to critical situations could. This may preferably be an already existing or known box, such as an ammunition box. If desired, the other properties of the box can be retained. Holes and / or openings in the wall of the crate are integrated into the crate at defined locations as exhaust openings for the integration of the venting system. These can be filled with a fusible material. This makes the box waterproof and dustproof. As a result, a retrofit is possible. Similar to the solution for insensitive ammunition, the exhaust openings are opened upon reaching a certain internal pressure or a critical temperature. The appropriate fusible material is turned off to the maximum allowable temperature. Through these openings, the internal pressure can escape.
Alternativ können die Öffnungen oder Durchbrüche auch mit einem definiert dünnwandigen Material oder einem Stopfen verschlossen werden. Bei Erhöhung des Innendrucks und Erreichen eines vorgegebenen Innendrucks werden der Stopfen oder das dünnwandige Material nach außen gedrückt. Stopfen und Material sind wiederum auf den maximalen in der Kiste einnehmbaren Innendruck abgestimmt. Eine Kombination beider Varianten hat den Charme, dass die Temperatur und der Innendruck als Parameter für das Venting- System berücksichtigt werden können. Unterhalb des Kistenverschlusses ist erfindungsgemäss ein Verschlussöffner eingebunden, der durch das Venting- System angetrieben wird. Dieser Verschlussöffiner ist so konzipiert, dass bei dem Auslösen des Venting- Systems an den Stirnseiten der Druck axial aufgefangen und damit der Verschluss der Kiste geöffnet wird. Das Venting- System selbst ist derart ausgebildet, dass weder die Stabilität noch die Umweltbeständigkeit der Kiste negativ beeinflusst werden. Das Venting- System verbessert zudem bei einer Munitionskiste die IM- Eigenschaften der Munition selbst.Alternatively, the openings or openings can also be closed with a defined thin-walled material or a plug. When the internal pressure is increased and a given internal pressure is reached, the plug or thin-walled material is pushed outward. Plug and material are in turn at the maximum in the box tuned internal pressure. A combination of both variants has the charm that temperature and internal pressure can be taken into account as parameters for the venting system. Below the box closure according to the invention a closure opener is involved, which is driven by the venting system. This shutter opener is designed so that when the venting system is triggered on the front sides, the pressure is absorbed axially and the shutter of the box is opened. The venting system itself is designed so that neither the stability nor the environmental resistance of the box are adversely affected. The venting system also improves the IM properties of the ammunition itself in an ammunition box.

Durch bzw. bei Erhöhung des Innendrucks in der Munitionskiste 1 werden das Material und / oder der (die) Stopfen 6 nach außen gedrückt, das Venting-System 3 ausgelöst. Die Erhöhung des Innendrucks kann sich auch durch eine Erhöhung der Temperatur einstellen, der die Munitionskiste unterliegen kann. Bei einem schmelzbaren Material / Stopfen 6 führt die Temperaturerhöhung zum Schmelzen des Materials / Stopfens 6. Auch dadurch kann das Venting- System 3 ausgelöst, die Bohrungen 5 freigegeben und der Innendruck abgebaut werden.By or when increasing the internal pressure in the
Zusätzlich zu dem Venting- System 3 ist erfindungsgemäss vorgesehen, bevorzugt unterhalb des Kistenverschlusses 4 einen so genannten Verschlussöffner 7 einzubinden, der durch das Venting-System 3 ausgelöst und / oder angetrieben werden kann, zusätzlich zur Öffnung der Kiste 1 per Hand. Dieser Verschlussöffner 7 ist so konzipiert, dass bei dem Auslösen des Venting-Systems 3 an den Stirnseiten der Druck des Materials und / oder Stopfens 6 oder der Innendruck selbst axial aufgefangen wird, der ausreicht, den Verschluss 4 der Kiste 1 zu öffnen. Dadurch wird der Verschluss 4 von der Kiste 1 weggedrückt, der Deckel 2 kann, hier im Rahmen eines Verschlussbügels, nachgeben. Dieser Deckel 2 gibt die Öffnung der Kiste 1 frei, der sich selbst zu einem geringen Grad öffnen kann. Eine derartige Anordnung zeigt die
Dazu werden das "definierte" dünnwandige Material sowie der Stopfen 6 mengenmäßig so gewählt, dass sie durch Einfluss des Innendrucks aus den Bohrungen ausgetrieben werden können.For this purpose, the "defined" thin-walled material and the
Als schmelzbares Material bieten sich neben synthetischen Materialien auch metallische Legierungen, wie Zinn-Bismuth an, bei denen die Schmelztemperatur bei ca. 138 liegt.In addition to synthetic materials, metallic alloys, such as tin-bismuth, in which the melting temperature is about 138, are also suitable as the fusible material.
