Definitions
- the invention relates to an artillery projectile with a projectile casing, in which a first active unit is arranged, and a pot-shaped bottom piece, which is closed at the rear by a detachable lid part.
- the pot-shaped bottom piece contains a propellant charge set, which is ignited when the projectile is fired, so that hot propellant charge gases can flow out through a floor nozzle provided in the cover part.
- a disadvantage of these known projectiles is that the space present in the bottom piece is not available for the active unit (payload) and thus the end ballistic active power (explosive effect, fog power or the like) is reduced in favor of an increased range.
- the end ballistic active power explosive effect, fog power or the like
- a relatively high Totlastanteil must be taken through the bottom piece with propellant charge in the known artillery projectiles.
- Projectiles can be designed differently and accordingly fulfill different tasks. With reference to these tasks, they can be broken down into, for example, explosive explosive, light and fog projectiles.
- gas generators are often integrated into the projectile structure, wherein a portion of the projectile length serves to accommodate the gas generator system.
- Other embodiments include a gas generator, but can be replaced by a hollow floor, if an increase in range is not desirable or necessary.
- the invention has for its object to provide an artillery projectile of the type mentioned, which despite the pot-shaped bottom piece with lid part has the largest possible end ballistic active power in the target area, if an increase in the range of the projectile by means of measures to Bodensogreduzierung is not required.
- the invention is based essentially on the idea of providing, instead of providing a hollow bottom, a rear component which can significantly absorb the effective capacity for achieving end-ballistic performances. For a user, this creates the opportunity, according to current needs (tasks) to make a conversion to a state without gas generator but with increased end ballistic performance. Alternatively, therefore, a removal or conversion to a state with gas generator or with respect to this state significantly increased effective capacity to achieve a final ballistic performance is possible. This is achieved, for example, by placing a second active unit in the pot-shaped bottom piece instead of a gas generator set for soil sediment reduction, which develops its intended action only after or upon activation of the first active unit main active unit.
- the artillery projectile according to the invention is an explosive projectile
- the two active units consist of explosive charges. It has proved to be advantageous if, in addition to the projectile casing also bottom piece and the cover part made of a fragment-forming material.
- the second explosive charge is preferably selected such that upon detonation of the first explosive charge a sympathetic detonation the second explosive charge takes place.
- an over ignition device for igniting the second active unit is arranged between the first active unit and the second active unit.
- the explosive charge initiated on the side of the spark-ignition forms a detonation wave which strikes the base in the direction of the rear-side boundary of the first active unit.
- first and second active unit provide for the initiation of the second active charge, so that in many cases already the steel bottom of the bottom piece is sufficient to fulfill a Kochzündfunktion, either by transfer / coupling the detonation wave from the first to the second active unit or in the course the fragment formed by the detonation from the metal bottom of the bottom piece, which penetrate with high energy into the explosive charge of the second active unit and initiate this.
- a particular design of the over-ignition device may be considered under certain conditions, e.g. for conditions of use at low temperatures or the use of, for example, insensitive explosives.
- the detonation wave then preferably strikes against a correspondingly shaped barrier which, in accordance with its geometry and material selection, is able to concentrate the energy in such a way that reliable initiation of the second active unit is achieved.
- Such configurations for concentration are known at shaped charges / cutting charges / projectile forming charges.
- the over-ignition can usually be done by means of ignition channel with or without the use of a delay element. In this case, only an ignition of the pyrotechnic charges is to be provided.
- the bottom piece can also be used for receiving a propellant charge for soil sediment reduction.
- the cover part after the release of the cover part, if appropriate, first remove the active unit from the bottom piece, then insert the propellant charge set into the bottom piece and then screw a cover part provided with a nozzle back onto the bottom piece.
- the pot-shaped bottom piece and the lid part are connected to one another by means of a screw connection.
- the projectile body consists essentially of a front part with detonator and (main) active unit. In the rear area is an interface for secure attachment of a rear component. The connection can be done by means of screwing etc. Due to this modular construction, the gas generator component or the active component which increases the active unit can complete the projectile. Depending on the type of ammunition, the end ballistic active body can make different contributions to the total endballistic performance. In addition to fragmentation performance on blasting projectiles, other performance spectra, such as fog or other effects depending on the structure or applied active substance, are also possible. Also combinations of different effects can be realized. The decision can be made individually and on site and the bullet can be equipped with it, unlike the explosive practice projectile known from DE 10 201 1010183 A1.
- FIG. 1 shows the longitudinal section of a projectile 1, here an explosive projectile, according to the prior art.
- the projectile 1 comprises the main components A - gas generator, B projectile casing, C active substance (in this case explosive of an explosive charge) and D - ignition device. This consists of a head fuse and possibly necessary transfer charges.
- the projectile casing B consists of a splinter-forming material.
- the main component A is formed by a pot with bore for the discharge of the generated gas, a gas generator set, a floor and an igniter floor and can preferably be screwed into the floor and thus secured to this.
- the longitudinal section of the rear-side region of the explosive projectile 1 is shown.
- the explosive charge is arranged as the first active unit 3.
- the head detonator and the rear side are followed by a pot-shaped bottom piece 4, which is closed by means of a screw connection 5 by a detachable cover part 6.
- This cover part 6 also consists of a fragment-forming material.
- a replaceable second active unit 7 is arranged in the pot-shaped bottom piece 4, which is a second explosive charge in the exemplary embodiment shown.
- the second explosive charge 7 is connected to a supercharging device 8.
- the Kochzünd listening 8 is formed by the bottom of the first active unit 3 itself.
- the bottom piece or over-ignition device 8 ' can be shaped such that the pressure wave generated by the first explosive charge 3 acts in the form of a shaped charge, etc. on the second explosive charge 7 (FIG. 3).
- the over-ignition can usually be done by means of ignition channel with or without the use of a delay element (not shown in detail). In this case, only an ignition of the pyrotechnic see sets is then provided.
- the active unit 7 is preferably held by the cover part 6 in the bottom piece 4 or fixed in this. By this simple connection, the active unit 7 is easily interchangeable with another unit or a gas generator A.
- the head detonator of the explosive projectile 1 activates the first explosive charge 3, which then also causes an initiation of the second explosive charge (active charge) 7 via the over-ignition device 8.
- the invention is not limited to the embodiment described above.
- the second explosive charge 7 is selected such that the detonation of the first explosive charge 3 causes a sympathetic detonation of the second explosive charge 7.
- active units 3 and 7 do not necessarily have to be explosive charges. Rather, the active units 3 and 7 may, for example, also be light or fog bodies. LIST OF REFERENCE NUMBERS
