Definitions
- the invention relates to a projectile according to the preamble of claim 1.
- Such a projectile is from the Patent Abstracts of Japan, Vol. 18, No. 314 (M-1621) from June 15, 1994 to JP-A-06 066 499.
- the warhead of the projectile is a winged KE rod, the one to take up the discharge pressure of the propellant charge with a three-part Sabot is populated, which is thrown off after the pipe exit. Then an engine located in front of the warhead is fired, the accelerating the KE rod, the one at the rear of the engine - by surrounded the employed gas outlet nozzles - is rigidly coupled.
- the KE staff must therefore first penetrate the engine when it is armored Ogive hits the armor of a target. By acceleration after exiting the gun barrel, the kinetic energy of this warhead is released increased - but then a significant amount of energy is lost again, if the KE rod the not yet burnt-out engine and its thick-walled Ogive penetrates, only to have an effect on the target object afterwards can.
- US-A-4 537 371 is a small-caliber explosive device for aerial combat known, which to increase the probability of hits via a beamrider control can be maneuvered.
- a valve-controlled dynamic pressure system is provided, which is via an annular nozzle at the projectile tip and an annular channel between the projectile shell and the warhead (Explosive charge) is pressurized. It becomes dependent of desired shear forces through obliquely backwards opening nozzles blown off specifically so that it is suitable for performing the maneuvers no aerodynamic rudder required.
- DE-A-41 37 843 states that they can be controlled remotely via the lookout group in the command post of a main battle tank can, if in the beam path of the laser rangefinder, which is directed towards the target anyway a modulatable laser beam is faded in then serves as a remote control beacon.
- the present invention has for its object to provide a projectile that by means of such a superimposition of a guide beam in the beam path of the range finder can be remotely controlled and optimally beyond this cost advantage a variable application scenario can be adapted.
- the full-caliber warhead and the one as a march engine serving full-caliber rocket engine are axially against each other offset between the rear section and the ogive of the projectile.
- Sufficient standoff for the subpoena and for the optimal formation of the shaped charge beam without extending the projectile yields a face Telescopic probe that can be extended from the ogive as a pre-installed one Impact contact.
- the laser guide beam remote control is not essential due to the exhaust gases from the rocket engine disabled, especially if it is z.
- a solid-fuel head torch with laterally inclined nozzles in the middle to front area of the projectile acts.
- the projectile can go deep from the gun barrel Immerse in the propellant charge cartridge as the annular space outside the projectile and behind its bottom for the small amount of propellant charge for comparatively slow start is sufficient.
- an inert gas cartridge in the propellant charge integrated for blowing out is provided.
- the initialization of the power supply and the Orientation sensors for the control device of the Projectile is fired after loading into the barrel of the fire head, just before lighting the Propellant charge, through a contact in the tailgate floor through the protective hood.
- the ammunition to be fired is not for the cartridge required axial space behind the rear part of the projectile bridged by a contact plunger, by means of which electrical initialization again from the bottom of the cartridge the power supply and the orientation sensors he follows.
- So ammunition is created depending on the design and location, i.e. by mere exchange, of the warhead in terms of the march engine in very different ways tactical scenarios can be used.
- the different Representatives of this family of ammunition are complete stowable just like the imported barrel weapon ammunition and manageable - with the further advantage that the projectiles despite the ammunition family according to the invention essential increased range a lower mechanical Experience launch load and through the laser remote control for web guidance and if necessary for one Ignition triggering can be used much more precisely.
- the semi-autonomous targeting does not require an expensive search head in the projectile.
- the remote-controlled projectile 11 has the caliber of a tubular ammunition and is therefore like this without any change requirements can be carried in a battle tank, for example and loadable in its main armament in the same way, so can be brought out of its tube, what diameter and Length of the projectile 11 concerns.
- the electrical power supply 19 for the control device 14 and its orientation sensor system 20 (with a g-sensor for determining the position of the outlet in the tube and an adjusting rollage sensor) and for the electrical ignition triggering behind the ignition device 12, but also in whole or in part be arranged in the rear part 21 of the projectile 11.
- Axially offset against each other and practically that filling the entire caliber within the projectile casing 18 are a warhead 22 and a marching engine 23 between Control device 14 including dynamic pressure motor 17 in the ogive 13 on the one hand and on the other hand the rear part 21 arranged.
- the march engine 23 is a solid end-burner designed, the combustion chamber in the direction of flight via a deflection device 24 in a number of Nozzles 25 opens, the periphery along the shell 18 against each other are offset and acute-angled with reference to the projectile longitudinal axis 26 inclined towards the tail part 21 open through the shell 18.
- the projectile is used against not or against semi-hard armored targets (like utility vehicles or Helicopter) is to be used, then it is with a Warhead 22 equipped, its explosive charge 27th arranged in front of the marching engine 23 and with a Splinter shell 28 is surrounded, which is preferably preformed Contains fragments, namely as shown in the steel sleeve 28 integrated and laterally radially outgoing Cubes 29 and axially acting balls 31 in the convex-spherical warhead-forehead 30 and possibly behind also an insert of axially outgoing balls 31.
- the explosive charge 27 can with the safety device in focus 32 via a detonator 33 from the ignition device 12 mission-dependent (via a timer, an impact detonator, a self-immolation order, or remotely controlled).
- a detonator 33 from the ignition device 12 mission-dependent (via a timer, an impact detonator, a self-immolation order, or remotely controlled).
- Projectile 11 in its warhead 22 with a jet-forming cone insert 34 in front of an inert Detonation wave deflector 35 equipped and in this Trap the warhead 22 behind the marching engine 23, thus arranged between this and the rear part 21.
- That subpoena 38 can eccentric for larger-caliber projectile designs between the control device 14 and the front Opening of the channel 36 may be located to the beam passage to influence as little as possible; for from normal caliber Pipes (105 mm) projectiles to be brought 11, the subpoena 38 is sufficient in the interest Caliber coaxially in front of the marching engine 23 with his central channel 36 arranged, as shown in Fig. 2.
- misplaced warhead 22 protrudes the security device 32 with the detonator 33 in the rear part 21 in. Otherwise, this is with a laser receiver 39 in front of a laser sensor 40 behind a central one Bottom opening 41 equipped, by means of a laser guide beam Remote control information from the control center of the Guns to the control device 14 for precise Target control are transmitted.
- the rear part 21 is also peripherally opposed to one another offset stabilization flights 42 equipped in the storage and firing position to the Outer wall of the shell 18 nestled in the area of the rear part 21 are and after leaving the launch tube spring-loaded from its retracted position (Fig. 1) swing out into its operative position (Fig. 2).
- These wings 42 have a low pitch compared to the longitudinal axis of the projectile 26 and thereby convey the projectile 11 during the cruise around the longitudinal axis 26 a low rotation. This is too low to stabilize the swirl to act - the rotation only serves to and to compensate for aerodynamic disturbances during the mission; and in particular the rotation enables with a single pair diametrically opposite each other Rudder 15 (offset in time depending on the rotation) Control in both pitch and yaw direction.
- the rear part 21 surrounded by a cup-shaped hood 43 which in In the course of starting the projectile 11 when leaving the Tube is thrown backwards.
- An isolated in the hood bottom inserted metallic ring 44 is used as a contact for electrical excitation of the control device 14 immediately before the discharge charge is ignited (see below) for the thermal batteries of the Activate power supply 19 and the position gyro in accordance with the solder detector in the orientation sensor system 20 to initialize.
- the projectile 11 is very submerged at the rear deep into his cartridge 45. Because the distance bridging not to the target with projectile 11 must be guaranteed by the start acceleration, but largely the march engine 23 is in Only one compared to ballistic fired ammunition so small amount of propellant charge 46 in the cartridge 45 required that the projectile 11 straight out of the Loosen the cartridge frame and leave the tube reliably what the wings 42 exhibit, the Hood 43 dropped and the marching engine 23 ignited becomes.
- This small amount of propellant charge 46 can without more in the hollow cylindrical space between the cartridge sleeve 47 and protruding into the cartridge 45 Projectile sleeve 18, including an axially flat one Ring area between the bottom 48 of the cartridge 45 and the bottom 51 of the projectile tail 21 become.
- the cartridge charge 46 becomes more common Way by means of a central firing pin behind the Sleeve bottom 48 ignited. In doing so, a senior Bridge to contact ring 44 as mentioned above the electrical Initialization (from power supply 19 and orientation sensors 20) before the firing pin takes effect.
- the cartridge 45 in the propellant space at least one inert gas cartridge 49 may be arranged is activated by the ignited propellant charge 46 and for example releases a larger volume of carbon dioxide, around the propellant charge reaction gases as directly as possible after leaving the projectile 11 from the pipe mouth drive out and so the gun, despite the low Suction at low muzzle velocity, quickly to be able to release again for reloading.
- the one with the propellant charge 46, compared to one ballistic projectile, low initial acceleration and low muzzle velocity brought out of the pipe Projectile 11 then starts its cruise engine 23, whose reaction gases 50 through the relatively far ahead the rear part 21 lying and oriented obliquely outwards Nozzles 25 laterally (obliquely backwards) from Projectile 11 are aligned so that these exhaust gases 50th the laser beam connection from the command post to the laser sensor 40 in the bottom of the rear part 21 do not interfere critically.
- the rocket-powered projectile can be in the laser beam control yourself, as in the above DE-OS 41 37 843 explained in more detail;
- remote triggering of the ignition device 12 according to today's parallel application "Remote control device for firing the warhead of a Projectile "(to avoid repetition full reference is made here) if the Warhead 12 does not detonate via impact or time criteria (for example for self-dismantling at not hit target) is triggered.
- a contact plunger 52 is provided, which telescopically engages in the separate cartridge 45 and by means of a coil spring 53, the length difference bridging to a normal barrel weapon cartridge, is pressed against the contact ring 44. Also this short cartridge 45 is again with an inert gas cartridge 49 to blow out the pipe, now through one Support star 54 (for centering the contact plunger 52) therethrough, fitted.
