Definitions
- the invention relates to a mortar grenade with a grenade body and one on the rear side tail unit connected to the shell.
- a pyrotechnic propellant charge is generally used as the drive in the form of e.g. Discs used at the rear end of the mortar shell, e.g. around the tail unit.
- Discs used at the rear end of the mortar shell, e.g. around the tail unit.
- a reduction in recoil forces could be done on the weapon side through a pipe return system and / or by extending the barrel, but lead such measures, among other things, to increase the manufacturing and maintenance costs and to limit the manageability of the grenade launcher.
- the invention has for its object the firing by the recoil forces total mortar shell load on weapon and weapon carrier for one Reduce the specified range of the grenade compared to existing systems or to significantly increase the range of the mortar projectiles with the same system load.
- the invention is essentially based on the idea of driving the mortar shell not a conventional pyrotechnic propellant charge, but to use a rocket engine, whose propellant charge is selected such that it is only a soft ejection of the Mortar grenade from the weapon barrel. After leaving the gun barrel you can the mortar grenade either by the same rocket engine or an additional one Rocket propulsion to be accelerated to a predetermined target speed.
- the target speed is determined, for example, by means of a mortar on the mortar arranged sensor, which is followed by an electronic evaluation unit, which the measured speed with a predetermined before the firing of the grenade Compare setpoint.
- the force is neutral Burn-up of the remaining propellant, i.e. the further burn-up of the propellant has an effect no longer (or no longer significantly) the further flight behavior of the grenade.
- Such a force-neutral burn-up can be achieved, for example, in that the propellant gases no longer generated by the rocket propellant through the rear outflow nozzles, but escape through openings arranged radially on the grenade.
- the propellant gases no longer generated by the rocket propellant through the rear outflow nozzles, but escape through openings arranged radially on the grenade.
- the electronic control device controllable valves are located in the corresponding gas lines with the electronic control device controllable valves.
- a satellite-based GPS navigation system intial measurement unit (IMV system)
- IMV system intial measurement unit
- pitot system a satellite-based GPS navigation system
- IMV system intial measurement unit
- pitot system a conventional pitot system
- 1 denotes a mortar grenade that is filled with an explosive 2 Grenade body 3 and a tail unit adjoining the rear of the grenade body 3 4 with tail 5 comprises.
- a rocket drive 6 is arranged, one with a rocket propellant 7 filled recess 8, a combustion chamber 9 and one up to the rear end 10 of the tail shaft 4 extending outflow nozzle 11 comprises.
- the outflow nozzle 11 can be closed by a controllable valve 12. Also are connected to the outflow nozzle 11 a plurality of radially outwardly directed gas lines 13, which can also be closed and opened by means of controllable valves 14.
- the mortar grenade 1 has one connected to an electronic control device 15 GPS sensor 16 for determining the speed of the mortar grenade 1 during its Flight on.
- the electronic control device 15 is via electrical lines 17 connected to the valves 12, 14.
- a target speed value is programmed into a memory of the control device 15. Then the rocket propellant 7 of the rocket drive 6 ignited by a detonator, not shown.
- the rocket propellant 7 is such designed that the mortar grenade after soft ejection at least the desired Speed reached after the rocket propellant 7 burned down.
- Control device 15 constantly by evaluating the GPS sensor 16 measured position data the flight speed of the grenade 1 and compares it with the specified target speed.
- FIG. 2 shows a further exemplary embodiment of a mortar grenade 1 'according to the invention shown. It is an intelligently controllable mortar projectile, which has both fold-out tail fins 5 'and fold-out control wings 19.
- the control device 15 ' is arranged on the bow side in the mortar grenade 1' and via a electrical line 20 with a GPS sensor 16 'and via electrical lines 17' with controllable valves 12 ', 14' connected.
- FIG. 1 contains the mortar grenade 1 'a chamber filled with explosives 2' as well as a rocket engine 6 '.
- the latter comprises a rocket propellant 7 'and a combustion chamber 9' with an adjoining outflow nozzle 11 '.
- a second can be found on the rear of the mortar grenade Rocket drive (booster) may be arranged, the propellant is selected such that it only to gently eject the grenade from the tube of the grenade launcher.
- the propellant is selected such that it only to gently eject the grenade from the tube of the grenade launcher.
- FIG.3 A corresponding embodiment is shown in Fig.3. Only the rear area of the mortar shell marked 1 ". In the tail unit this grenade 1 "is both a foldable tail unit 5" and a first rocket drive 6 "is provided.
- the second rocket drive is identified by the reference numerals 21 and its propellant is provided with the reference number 22.
- the first rocket drive 6 "integrated in the tail unit takes over the further acceleration the grenade 1 "until the predetermined one and in a memory of an electronic Control device stored target speed of the grenade 1 "is reached.
- the thrust jet can then turn to radially arranged openings of the Grenade 1 "are deflected, which are not shown in Figure 3 for reasons of better clarity are shown.
