Definitions

  • the invention relates to a free-flight rifle for artillery projectiles with a loading trough in a predetermined distance behind the gun, flush with the cargo space, into which the projectile can be inserted, and to a mechanical acceleration member acting on the rear of the projectile, which is designed as the free end of a pivotable attachment lever , which is connected to a cylinder drive via a path transmission device with a transmission ratio greater than 1.
  • Rack and pinion attachments are based on a principle similar to that of chain attachments, in which a gear drives a rack forward, which causes the attachment process. Above all, this device has the disadvantage that a long space must be available behind the gun to accommodate the rack, which, as a rule, cannot be the case with tank artillery guns.
  • Telescope attachments have also become known in which the attachment process is carried out by a telescopic pneumatic cylinder takes place, which is arranged behind the gun.
  • This arrangement is more suitable for being integrated into armored artillery guns, but in turn also has the disadvantage of being quite slow and in particular taking up valuable time for the withdrawal process.
  • this acceleration is generated either on the basis of a prestressed spring or by means of a controllable hydraulic cylinder.
  • An advantage of the free flight attachments is the high speed with which the attaching process takes place and in particular the fact that no time is wasted for withdrawing the attachers from the cargo space.
  • a major disadvantage of the known free-flight attachments is that the effort for control technology, valves, pressure and compensation accumulators in hydraulic and mechanical systems is so great that in addition to the uncomfortably high effort, which reduces the reliability of the system, there is also a lot of space inside a vehicle is required to integrate the system.
  • free-flight attachments with a preloaded spring there is still the problem that the spring cannot be preloaded sufficiently when using small loading quantities.
  • the invention is based on a free-flight attachment with the features described at the beginning and in the preamble of claim 1.
  • a free-flight attachment is described, for example, in DE-A-2 320 398.
  • the pivotable attachment lever acting on the rear of the projectile is connected to a hydraulic cylinder via a planetary gear.
  • BE-A-656 276 describes a projectile rifle in which the projectile is pushed into the loading position under the action of a hydraulic cylinder without the interposition of a path translation device. It is also proposed in this connection to use a pneumatic cylinder instead of the hydraulic cylinder.
  • the invention has for its object to design a free flight attachment of the type mentioned in such a way that, on the one hand, it can be started at high speed, but on the other hand only very little technical effort is required, the functional reliability is independent of the loading quantity and very little space is required .
  • the invention is based on the basic idea of generating the force required to accelerate the projectile (approx. 5000 Nm) using a pneumatic cylinder. Since large forces have to be made available very quickly when artillery shells are used, but the positioning accuracy is insignificant, a pneumatic system is considerably superior to the hydraulic system.
  • a particularly large pneumatic cylinder with a short stroke can be used, the path of which is translated by the path translation device, for example in a ratio of 5: 1.
  • the pneumatic cylinder is chosen so large that despite the translation of 5: 1, for example, the necessary force (approx. 5000 Nm) is still available at the point of impact of the projectile.
  • a slow pressure build-up in the cylinder which is normally out of the question, is preceded by a compressed air accumulator upstream of the pneumatic cylinder, and the pneumatic cylinder is connected to the compressed air accumulator via a quick-opening control valve with a particularly large cross-section. It is advantageous if the pressure accumulator and pneumatic cylinder are designed in such a way and the pre-pressure prevailing in the pressure accumulator is so much above the maximum permissible pressure of the pneumatic cylinder that after opening the control valve and the sudden pressure equalization in the compressed air accumulator and pneumatic cylinder that the maximum pressure permissible for the pneumatic cylinder prevails .
  • the rear end 1 of a gun barrel is shown in a highly schematic representation, on which a free-flight attachment is arranged, with a loading trough 2 arranged in alignment with the cargo space 3 of the gun barrel 1, into which a projectile A can be inserted.
  • the actual gun barrel 5 with trains and fields connects to the cargo space 3 via a conical part 4.
  • the free flight attachment furthermore has an attachment lever 6 which can be pivoted about a pivot axis 9, the free end of which engages on the rear side of the projectile A inserted into the loading trough 2 via a guide roller 7.
  • a transmission linkage 13 engages, which is connected via an articulated connection 14 to the piston 11 of a pneumatic cylinder 10, the piston movement of which takes place against a return spring 12.
  • the articulation point 8 on the attachment lever 6 is selected so that the ratio of the distance of the free end of the attachment lever 6, i.e. the distance of the guide roller 7, from the pivot axis 9 to the distance of the articulation point 8 from the pivot axis 9, which is the ratio of the translation of the movement by Attachment lever 6 is about 5: 1.
  • the inlet 15 of the pneumatic cylinder 10 is connected via a quick-opening control valve 17 with an electromagnetic actuating part 18 to a compressed air reservoir 19, which in turn is connected via a further control valve 20 with an electromagnetic actuating part 22 to a compressed air source 21.
  • the cylinder outlet 16 of the pneumatic cylinder 10 can be connected to the outside air via a control valve 25 with an electromagnetic actuating part 26.
  • the electromagnetic actuating parts 18, 22 and 26 are in an electrical control circuit, the actuating part 18 being switchable by a switch 24, the actuating part 22 by a switch 23 and the actuating part 26 by a switch 27.
  • FIGS. 1 to 3 The operation of the free-flight adapter shown in FIGS. 1 to 3 is as follows: In the starting position shown in FIG. 1, the projectile A is inserted into the loading trough 2 manually or by a loading mechanism. The free end of the attachment lever 6 is located behind the floor and lies with the guide roller 7 on the floor of the floor.
  • the compressed air reservoir 19, controlled by the filling valve 20, is filled with compressed air.
  • the control valve 17 is opened via the electromagnetic actuating part 18 and the compressed air is suddenly introduced into the pneumatic cylinder 10.
  • the piston 11 moves upwards at high speed, and in its end position, equality of pressure between the compressed air reservoir 19 and the pneumatic cylinder 10 is achieved.
  • the movement of the piston 11 is transmitted via the connecting rod 13 to the attachment lever 6, the entire arrangement being chosen so that the connecting rod 13 is subjected to tension, which reduces the risk of buckling.
  • the attachment lever 6 transmits its moment to the floor A in the loading trough 2 and this starts in the direction of the cargo space 3 in motion. This state is shown in Fig. 2.
  • the projectile A is in the cargo space 3 on the flight towards the piecing cone 4.
  • the articulated connection 14 between the linkage 13 and the piston 11 compensates for the lateral deviation of the movement of the piecing lever 6.
  • vent valve 25 is opened by switching on the switch 27 via the actuating part 26, as a result of which the pneumatic cylinder 10 is vented and the piston 11 returns to its starting position under the action of the return spring 12.
  • the pivot axis 9 of the attachment lever 6 is in a plane E1, which is perpendicular to the longitudinal axis L of the loading trough 2, between the front and rear ends of the loading trough 2 and at a predetermined distance Arranged from this longitudinal axis L and the attachment lever 6 is guided from the plane E1 into a plane E2, which is arranged perpendicular to the longitudinal axis L behind the loading trough 2, the attachment lever 6 at Reaching the plane E2 has a bend, so that its free end 6a lies essentially in this plane E2. 3, this arrangement and design has the advantage that the return of the gun barrel 1 in the direction R when firing the shot, which can be done up to the position shown in dashed lines in FIG. 3, is not hindered by the attachment lever 6 .
  • the described free-flight adapter can be constructed from very few modules which can be arranged in a compact manner. This opens up the possibility of redundant expansion in that two identically constructed free-flight attachments can be arranged very close to each other on a gun barrel.
  • a piston cylinder is used as the pneumatic cylinder.
  • a pneumatic membrane cylinder with a large cylinder area can also be used, by means of which the device can be activated particularly quickly.
