Definitions
- the invention relates to an arrangement for preventing premature ignition of an active charge of a projectile to be ignited by an adjustable delay detonator, which is fired by a discharge charge from a launch tube, according to the preamble of patent claim 1.
- an arrangement is known from DE-PS 35 43 939 known.
- the acceleration sensor and the tube sensor are prestressed into an end position, the acceleration sensor is coupled via a locking bolt to a delay sensor loaded by a spring, and a transfer charge is located between the delay piece and the active charge, which can be displaced by a spring braked by an inhibitor.
- the object of the present invention is therefore to design the known arrangement in such a way that the production costs are considerably reduced, but at the same time the safety and functional reliability is increased still further.
- the solution to this problem results from the characterizing features of patent claim 1.
- the fuse arrangement is accommodated in the base region of the throwing body and represents the connecting link between the discharge charge or a special ignition charge assigned to it and the active charge or a special ignition charge assigned to it.
- the arrangement has two mutually parallel pyrotechnic delay sets, which extend in the firing direction (arrow A), hereinafter referred to as delay sections, namely a first delay section 10 and a second delay section 11.
- the first delay section 10 is followed coaxially by a firing pin 12, the tip of which 12a in extends into a channel 13 which extends transversely to the firing direction A.
- a tube sensor 14 in the form of a bolt with a retracted shaft is slidably accommodated in the channel 13, the tip 12a of the firing pin 12 resting on the shaft of the tube sensor in the position shown in FIG. 1, or the firing pin 12 otherwise from the tube sensor 14 in the starting position is held.
- a short pipe section 15 extends from the channel 13 in the firing direction A, at the bottom of which there is a central firing cap 16 which is used to ignite the not-shown effective charge of the projectile.
- the already mentioned second deceleration piece 11 also opens into the channel 13, as well as a channel 17 which also extends in the firing direction A and in which an acceleration sensor 18 slides.
- the acceleration sensor 18 engages with its tip 18a in a recess 14a on the jacket of the tube sensor 14.
- the arrangement also has elastic locking rings 19 which serve as catches for the sliding parts of the arrangement, that is to say for the firing pin 12, the tube sensor 14 and the acceleration sensor 18.
- Fig. 1 the arrangement is shown in the safety position.
- the tube sensor 14 lies with its shaft between the firing pin 12 and the percussion cap 16, whereby the ignition chain is interrupted by the delay piece 10 for active charging.
- the tube sensor 14 is secured in this position in two ways, on the one hand by the wall of the launch tube indicated at 20, in which the projectile with its casing 21 is inserted, and on the other hand by the acceleration sensor 18, which has its tip 18a in the recess 14a of the pipe sensor 14 engages. If the ejection charge is now ignited via a usually electrical igniter, then there is a sequence as indicated in FIG. 2. This means that the hot gases of the ignition charge set the projectile in motion and at the same time ignite the two delay pieces 10, 11. As soon as the projectile has reached its maximum acceleration, the acceleration sensor 18 moves out of its detent (upwards in FIG.
- the acceleration sensor 18 is therefore dimensioned in such a way that it only moves into its position releasing the pipe sensor 14 when the projectile has reached an acceleration which is sufficient for the projectile to be shot ballistically beyond the zone of the foreline safety. Should the projectile be braked strongly by some obstacle within the fore-pipe safety zone after leaving the pipe, despite this acceleration, then the acceleration sensor 18 moves again in the opposite direction into the pipe sensor 14, who has not yet moved outward, locking position back.
- the delay time of the delay piece 11 is set so that at the time of its burn-through the - correctly accelerated - projectile has reached the end of the fore-pipe safety zone.
- the delay time of the delay piece 10 is set to the desired point in time of the ignition of the active charge, so that in any case the delay time of the delay piece 10 is longer than that of the delay piece 11. Should the delay time of the delay piece 10 be shorter than that of the delay piece due to a malfunction 11, the ignition chain remains broken and in safety.
