Definitions

  • the invention relates to a Geschoßansetzer for an artillery gun with the Features of the preamble of claim 1.
  • CH 662 175 A is an acceleration device for a loading device of a gun for the introduction of a projectile in the gun barrel described with a behind the gun barrel Sled on which the projectile to be loaded is launched and which by means of Roles on a guided tour.
  • About an arm of the carriage is a arranged below the carriage hydraulic cylinder unit emotional.
  • To the impulse transmitted to the projectile according to the To adjust tube elevation is in a return line of the hydraulic cylinder unit a throttle is turned on, which can be configured variable. How and according to which regularities the variable throttle is set is not described in the document.
  • the invention has the object of providing a bullet with the Features of the preamble of claim 1 in such a way that the strong increase in Ansetz mechanism with decreasing elevation and the resulting disadvantages are avoided.
  • the basic idea of the invention is that of the piston-cylinder drive the batch applicator applied piecing with decreasing Elevation to reduce so far that the attachment speeds at different elevation angles within a given, predetermined Remain area.
  • Fig. 1 shows the rear end of the barrel 1 of an otherwise not shown Artillery gun, on which the bottom piece 2 with a sealing wedge 2.1 is arranged.
  • the weapon barrel 1 has in the area in which the bullet is to start, a transition cone 1.1 and is the trunnion axis 1.2 swiveling.
  • a projectile transfer arm 2.2 To the same trunnion axis 1.2 pivotable is a projectile transfer arm 2.2, on which a bulldozer is arranged with a base frame 3, on which a guideway 5 attached on which a carriage 4 is parallel over sliding guides in one direction led to the tube core axis R.
  • the carriage 4 is provided with a piston-cylinder drive 6, by which it is accelerated in the direction of arrow B. can.
  • a shock absorber 7 is arranged, the on his out of the carriage forward led out piston rod 7.2 has a stop 7.3.
  • Projectile 8 On the carriage 4 is to be attached Projectile 8, and at the rear end of the carriage 4 is an attack element 4.1 arranged.
  • the stop In the End position of the carriage 4, the stop is 7.3 directly at the rear end of the weapon barrel 1.
  • the piston-cylinder drive 6 is controlled by a pneumatic control system 19th driven, which is shown in Figs. 2 and 3 in more detail. As shown in FIG. 2, is the working port 6.1 of the piston-cylinder drive 6 via a quick-opening, electromagnetically actuated control valve 10 on the one hand with an outlet and on the other hand with a pressure reduction unit 20, the will be described in more detail below, and a compressed air reservoir 11 connectable.
  • the pressure reducing unit 20 is in the usual way to a compressed air source 14 connected.
  • the return port 6.2 of the piston-cylinder drive 6 is a quick exhaust valve 12 on the one hand to a Outlet and on the other hand via a second electromagnetically controllable Control valve 13, with the interposition of a pressure limiter 16, on the one hand connectable to the compressed air reservoir 11 and on the other hand to an outlet. Due to the short switching time of the control valve 10 is achieved that the required volume flow quickly at the piston-cylinder drive 6 available stands.
  • the acceleration is initiated, there is a sudden pressure available, through which the piston is guided to the front and the carriage accelerated. This is the one located on the other side of the piston Air column during the acceleration stroke via the quick exhaust valve 12th pushed out. At the end of the acceleration stroke, the carriage 4 is decelerated and the carriage returned to the starting position.
  • the pressure reduction unit 20 which, as shown in FIG. 3, a Proportional pressure control valve 20.1, which has an electrical control unit 18 is controlled.
  • the electric control unit 18 are the determined for the respective elevation of the gun barrel 1 control signals from the fire control system 17 or another position transmitter, e.g. the Encoder 17.1 supplied to the gun. This ensures that at decreasing elevation of the piecing pressure is reduced, according to regularities as explained at the beginning and below of Fig. 4 are illustrated again.
  • the input pressure P 1 of the pressure reducing unit 20 is the pressure supplied by the pressure source 14, while the output pressure P 2 corresponds to the reduced pressure in dependence on the elevation angle.
  • the proportional pressure control valve 20.1 is connected in parallel with a manually actuatable pressure reducing valve 20.3.
  • the proportional pressure control valve 20.1 and the pressure reducing valve 20.3 are selectively connected via an electromagnetic switching valve 20.2 with the quick-opening control valve 10, wherein the circuit is such that the electromagnetic switching valve 20.2 in the de-energized state, ie in an emergency, the manually operable pressure reducing valve 20.3 with the quick-opening control valve 10 leading line connects.
  • FIG. 4 shows the dependency of the attachment speed V Ans on the elevation angle El in graphic representations.
  • the dashed curve ST shows the dependence of the attachment speed from the elevation angle in a conventional Geschoßansetzer after the state the technique in which over the entire elevation range with the same Starting pressure is worked.
  • Curves I and II define upper and lower limits for the range of attachment speeds allowed at certain elevation angles.
