Definitions

the invention relates to a projectile rifle for artillery with the features in the preamble of claim 1.
a problem that occurs with such free-flight launchers is that, on the one hand, a high acceleration of the sled-projectile system is necessary to achieve the highest possible attachment speed, and on the other hand, the direction in which the projectile detaches from the sled during braking is aligned with the tube core axis with high accuracy the weapon must lie so that there is no contact between the projectile and the inside walls of the weapon when flying through the base piece and the cargo space of the weapon, which can lead to damage to the projectile or to the weapon.
the invention has for its object to provide a projectile rifle with the features from the preamble of claim 1 so that even at high acceleration during the braking process no disturbing forces occur that could negatively affect the projectile during the attachment process.
the basic idea of the invention is to brake the carriage by running directly onto the rear end of the gun barrel with the interposition of a shock absorber.
This has the consequence of the very large mass of the gun barrel that no tilting movement of the carriage occurs during the braking process, as is the case when braking is carried out, for example, by stops on the base frame of the guideway of the carriage or by stops in the drive device.
the intermediate shock absorber is arranged on the longitudinal center plane of the slide and preferably runs at least approximately through the center of gravity of the slide, which further ensures that no disturbing moments occur during the braking process.
the carriage has longitudinal guide rails for the projectile and the engagement element arranged at the rear end of the carriage engages the projectile above the central axis of the projectile. This prevents the projectile from performing a movement when it detaches from the slide, with the tip rising upwards. It is rather in reached an absolutely stable position during the acceleration phase even on different storeys.
shock absorber only absorbs a certain proportion of the kinetic energy of the sled when braking, the remaining energy can be used to return the sled to the starting position, the excess energy still present when the starting position is reached being absorbed by another shock absorber which is incorporated into the drive system can be integrated.
a pneumatic system is preferably used to drive the slide, in which the compressed air required to operate the piston-cylinder drive is stored in a compressed air reservoir and is suddenly supplied to the piston-cylinder drive by means of a quick-opening control valve.
Fig. 1 shows the rear end of the gun barrel 1 of an otherwise not shown artillery gun, on which the bottom piece 2 is arranged.
a projectile rifle is arranged with a base frame 3 on which a guide track 5 is fastened, on which a carriage 4 is guided in a direction parallel to the barrel core axis R via slide guides 5.1.
the carriage 4 is coupled via a connecting element 9 to a piston-cylinder drive 6, by means of which it can be accelerated in the direction of arrow B.
a shock absorber 7 is arranged, which will be explained in more detail below and which has a stop 7.3 on its piston rod 7.2 which is led out of the slide to the front.
the projectile 8 to be attached lies on the guide rails 4.3 arranged in the longitudinal direction in the carriage 4.
the carriage 4 with the projectile 8 is shown in the starting position before the acceleration process begins.
the end position of the slide is indicated in dashed lines by the end position of the piston rod 6.3 of the piston-cylinder drive 6 and the end position of the stop 7.3 of the shock absorber 7.
stop 7.3 is located directly at the rear end of the gun barrel 1.
the shock absorber 7 is arranged on the longitudinal center plane M of the carriage 4 and its central axis m runs through the center of mass of the slide 4 in a manner not particularly marked.
a shell-like engagement element 4.1 which, as can be seen from FIGS. 5 and 6, is designed asymmetrically to the longitudinal center plane of the slide, since the projectile 8 is inserted from one side.
the upper edge of the rear wall 4.2 of the engagement element 4.1 runs in such a way that the engagement point lies above the central axis A of the projectile 8 lying on the guide rails 4.3.
the shock absorber 7 shows the structure of the shock absorber 7 in more detail.
the shock absorber 7 has a cylinder 7.1, in which a piston 7.4 is guided, which carries a piston rod 7.2, at the outer end of which, not shown in FIG. 7, the stop 7.3 is arranged.
the piston rod 7.2 is firmly connected to the piston 7.4 and the guide rod 7.7 and is guided in a holder 7.6 when the piston returns via the guide rod 7.7.
a friction spring 7.5 is arranged in the space between the guide rod 7.7 and the inner wall of the cylinder 7.1. Friction springs of this type are generally known and their structure can be seen in FIGS. 7a and 7b, which represent an area at the two spring ends.
the friction spring 7.5 is made up of a number of closed outer and inner rings, the outer rings on their inside and the inner rings on their outside having conical surfaces on which the outer and inner rings touch. If the spring pillar formed from the outer and inner rings is loaded in the direction of the spring axis, the conical surfaces slide into one another and cause the outer rings stretch and the inner rings decrease in diameter. Since outer inner rings are made of spring steel, an elastic compression occurs with correspondingly high forces, the special characteristic of this spring being the strong friction damping due to the friction between the outer and inner rings. In this way, about 2/3 of the energy introduced is converted into thermal energy by friction.
a shock absorber constructed in this way is particularly advantageous for the projectile attachment described, because in this way the greater part, that is to say about 2/3, of the kinetic energy present in the braking position of the slide 4 is converted by friction, while the remainder is used for the return of the slide 4 is available in the starting position.
a shock absorber that converts the entire kinetic energy of the slide when braking and to return the slide to the starting position with the aid of the drive system.
the piston-cylinder drive 6 of the carriage 4 can in principle be driven hydraulically or pneumatically.
a pneumatic drive with a control system as shown in FIG. 8 is particularly advantageous.
the working connection 6.1 of the piston-cylinder drive 6 can be connected via an electromagnetically actuated control valve 10 on the one hand to an outlet and on the other hand to a compressed air reservoir 11.
the compressed air reservoir 11 is connected to a compressed air source 14 in the usual way.
the return connection 6.2 of the piston-cylinder drive 6 is via a quick exhaust valve til 12 on the one hand to an outlet and on the other hand via a second electromagnetically controllable control valve 13 with the interposition of a pressure limiter on the one hand to the compressed air reservoir 11 and on the other hand to an outlet.
the control valve 10 is designed as a quick-opening valve, which is characterized by a very short switching time.
