Definitions
- Inductive ignition system especially for infantry weapons
- the invention relates to an inductive ignition system, in particular for infantry weapons, according to the preamble of claim 1.
- Inductive ignition is preferably used for medium-caliber machine guns.
- a primary coil is arranged in the weapon housing, which interacts inductively with a secondary coil in the ignition system of the cartridge and transmits the ignition energy required for ignition.
- the ignition energy is provided by an external supply (battery, vehicle electrical system, etc.).
- cables must be laid.
- DE 32 31 369 C1 describes an exemplary secondary coil for the cartridge.
- the invention has for its object to develop an inductive ignition system according to the preamble of claim 1 so that the required ignition energy is generated and provided internally without extra supply.
- a weapon breech block is arranged in the weapon housing and can be displaced from a cocking position into a firing position, in which the primary coil is located and in that an inductive shock generator is provided for generating the ignition energy, the coil system of which is arranged in the weapon breech block and the magnet system of the weapon housing is, when moving the weapon breech body from the cocking position to the firing position, the coil system glides past the magnet system and induces the required ignition energy in the coil system.
- an electronic circuit for the temporary storage and / or processing of the ignition energy generated in the coil system of the shock generator and for timely transmission to the primary coil is provided in the weapon breech body.
- a capacitor is expediently used for intermediate storage and a rectifier for processing.
- the weapon breech body is preferably displaceable against the force of a spring from the firing position to the cocking position and is moved for cocking via a loading lever.
- the ignition energy is generated by an inductive shock generator.
- a "passing" past permanent magnets causes a coil system to be flooded with changing magnetic fields, an induction voltage being tapped at the terminals of the coil system.
- the inductive shock generator is part of the fixed weapon housing and the movable weapon breech body.
- the ignition energy storage or intermediate storage in the capacitor and the functional energy transfer into the cartridge via suitable control electronics is integrated in the movable weapon breech body.
- the invention therefore has the following advantages:
- the weapon breech body (movable) - hereinafter also called the breech - are the primary coil, a control electronics, not specified, which releases the energy stored in the capacitor (generated by means of an inductive shock generator) on the primary coil when the cartridge is in the chamber and the breech is securely closed (a query may be made beforehand via a sensor or an electronic time delay is provided. It must be ensured that the closure is really closed.).
- the shock generator is "quasi" divided into two.
- the energy stored in the capacitor is discharged onto the primary coil via an electronic switch for the purpose of ignition This in turn creates a alternating magnetic field, which is coupled into the inductive igniter of the cartridge; the cartridge fires.
- the weapon breech body moves back again. The process starts again (e.g. in the event of a continuous fire or burst of fire).
- the weapon breech body must be brought into the starting position using a suitable device (e.g. loading lever) (it is then in the cocking position). If a shot is to be fired, the weapon breech body is moved forward via the trigger and a corresponding mechanism, the functional sequence is in accordance with the process described.
- a suitable device e.g. loading lever
- FIG. 1 shows schematically the mode of operation of the inductive ignition system according to the invention
- Fig. 2 in sections through a weapon housing with a movable breech the operation of the invention
- Fig. 3 shows the inductive shock generator or the arrangement of the coil system in the breech and the magnet system in the weapon housing.
- Fig. 1 shows schematically the operation of an inductive ignition system for infantry weapons.
- a coil system 7 Arranged in the weapon breech body 5 is a coil system 7 which, together with a magnet system arranged in the weapon housing 1, has a shock generator 6 forms.
- an electronic circuit 9 With, for example, a rectifier 14, a capacitor 15 and an electronic switch 16.
- a primary coil 2 At the end facing the cartridge 4, a primary coil 2 is arranged which, when ignited, supplies energy to one arranged in the cartridge 4 Secondary coil 3 transmits.
- the weapon locking body 5 When the weapon is loaded, the weapon locking body 5 is brought into a cocking position against the force of a spring 10 using the loading lever 11 (only indicated schematically). This clamping position is shown in dashed lines.
- the spring 10 is tensioned and wants to push the weapon breech body back into the firing position (previously described).
- a trigger 12 firing lever etc.
- the coil system 7 slides in the weapon breech body 5 past the magnet system 8 in the weapon housing 1. In this case, an ignition voltage is generated in the coil system 7 and passed to an electronic circuit 9.
- the connecting wires or conductor tracks are not shown.
- This electronic circuit 9 contains at least one capacitor 15, a rectifier 14 and an electronic switch 16.
- a timer or a delay circuit should also be included, which only applies the ignition voltage to the primary coil 2 when the weapon breech body 5 is in the firing position. Before that, it must be ensured that the weapon breech 5 is really in the firing position. This could e.g. B. happen via a sensor element.
- Fig. 2 shows in individual sections the operation of the inductive ignition system.
- 2a shows in section a weapon housing 1 in which a displaceable weapon breech body 5 is arranged.
- a cartridge 4 is in the feed, but not yet in the weapon barrel 13.
- a coil system 7 is arranged in the weapon breech body 5 and a magnet system 8 in the weapon housing 1. Both together form a shock generator. It is not shown that there is still an electronic circuit and a primary coil in the weapon breech body 5 (see FIG. 1).
- Fig. 2a shows the weapon breech 5 in its firing position. The spring 10 is relaxed.
- Fig. 2b shows the same object as Fig. 1a, only the upper part is cut off.
- Figures 2c, d, e also show the same section.
- Fig. 2c the weapon breech 5 is in its cocked position.
- the spring 10 is tensioned and wants to move the weapon breech body 5 into its firing position.
- a cartridge 4 is located in front of the gun barrel 13.
- the weapon breech body 5 moves in the direction of the firing position. This is shown in Fig. 2d.
- the coil system 7 slides past the magnet system 8 and a voltage is induced in the coil system 7. This is stored in the electronic circuit or the capacitor, not shown.
- Fig. 2e shows the weapon breech body 5 in its firing position.
- the electronic circuit or the capacitor deliver their stored energy to the primary coil (not shown) (see FIG. 1) and this induces a voltage in the secondary coil in the cartridge 4, which ignites the cartridge 4.
- the primary coil not shown
- the inductive shock generator which consists of a coil system 7 in the weapon breech body 5 and a magnet system 8 in the weapon housing 1.
- the coil system 7 consists of a soft magnetic yoke 17 on which coils are wound.
- Two or more shock generators are preferably arranged in the weapon breech body 5.
