Description

Technical field

The invention relates to a firing device for a cartridge-less ammunition weapon which can be used in automated artillery and tank systems achieving high cadence without direct operator intervention.

BACKGROUND OF THE INVENTION

Previously known launch systems are directly provided by the operator, by inserting the initiator directly into the breech mechanism after each wound, or using a drum magazine for 6 to 10 initiators stored in the butt of the barrel. The disadvantage of these systems is the necessity of the presence of the operator, lengthy and often risky insertion of the initiator in the conclusion of a sharply loaded weapon, problematic replacement of the initiator in the event of failure, problematic handling of the small initiator in gloves in winter conditions. The use of the drum magazine is an advancement, but there are problems with sealing the transitions between the magazine, the butt and the barrel, which in powerful weapons can lead to erosion of the contact surfaces from the prefushes and thus necessitate replacement of individual components. A major disadvantage is the multi-angle opening, which increases the energy requirement of the initiator. Another disadvantage is the small number of initiators in the magazine, the high demands on the stopping space and the demands on operation in mode firing. Attempts to initiate a charge by an electric discharge are known only from literature searches, without known practical introduction.

SUMMARY OF THE INVENTION

These deficiencies are eliminated by the firing device of the cartridge-free ammunition, the essence of which is a programmed initiator slider slidably mounted directly in the breech mechanism of the weapon, including the hole, while the initiators are stored in a double-row straight magazine. A small stroke firing pin, an initiator puller and an initiator ejector are housed in the initiator plug. The initiator plug is mechanically operated by a spring and a tensioning hammer, which also serves as a lock within the shot. The tensioning hammer is mounted at one end of the pin with the firing pin, the other end being the lever of the slip mechanism. The firing pin is operated via a spring pin, whereby the pressure pin serves as a safety lock for locking the slide. A straight bore opening is provided in the axis of the initiator inserter, one end of which forms the charge chamber of the initiator and the other end opens into the cartridge chamber of the weapon. The firing device is formed on one side by a bracket for the container and handling and on the other side ended with a sealing ring with a fuse.

A new, higher effect of the launcher is that it can fire at least 30 rounds in an automatic cycle without operator intervention. It radically increases charging safety, as the initiator does not insert into the bore hole until the operator has completely locked the slide. In case of accidental failure of the initiator with the same electro-pulse, it throws the failed and fires a new one without the necessity of the operator. The sieve hole is short, straight, solid without transitions, which increases the safety and reliability of firing. In the case of electrical failure is the possibility to manually control the device with a simple launch lever directly from the cabin of the commander. The device is simple, easy to dismantle and replaceable. It does not place increased demands on operator training. After a simple replacement of the cartridge by the operator, a further 30 rounds can be fired in burst mode.

BRIEF DESCRIPTION OF THE DRAWINGS

The technical solution is explained in more detail by means of drawings. In FIG. 1 is a cross-sectional view of the entire apparatus; FIG. 2 shows a section through the pin of the slip mechanism and FIG. 3 cut through the firing pin and initiator puller.

DETAILED DESCRIPTION OF THE INVENTION

The initiator plug 1 is slidably mounted in the rear body 2 of the weapon breech mechanism 39. It is actuated by a spring A 3 and a tensioning hammer 4 which is mounted on pin A 5 with bushes 6. The initiator insert 1 comprises a firing pin 8 actuated by a spring B 9 and a puller 11 of an initiator actuated by a spring C 12. determines the bayonet cap 10 of the firing pin. The initiator puller 11 is mounted on pin B 13, with its barb 14 extending into the space of the initiator chamber 15. On pin A 5, together with a tensioning hammer 4, is a firing pin 16 operated by a pin 17 and a spring D18. In the rear body 2 there is a recess 26 for the magazine and for receiving the ejector 27, which is fastened over the washer 28 by screws C 29. The bracket 30 is mounted in the rear body 2 on the flange A 31 and fastened by screws D 32. F 34 forms a stop position in the butt of the barrel. The flange B 35 with the insert A 36 encloses the space 37 of the initiator insert 1, while on the other side of the space 37 there is an insert B 38 for guiding and directing the initiator into the initiator chamber 15. The front body 19 is connected to the rear body 2 by means of bolts B 20. The front body 19 is formed at one end by a charge chamber 15 of the initiator with a through hole 21. The other end 22 of the front body 19 is formed by a sealing ring 23 with a spring-operated fuse 24.

By pivoting the pin A 5 from the basic position in the direction of the arrow, the initiator plug 1 is first unlocked and then moved to the extreme position. Simultaneously with the pin A 5, a firing pin 16 is rotated, which compresses the spring D 18 via the pin 17. If there is an empty cartridge in the initiator chamber 15, it is extracted by the initiator puller 11. After reaching the limit position, the initiator plug 1 returns to the home position by means of the spring A 3. At the same time as the initiator plug 1 is moved, the tensioning hammer 4 is pivoted. When the charging edge of the initiator plug 1 reaches the edge of the bore 26 where the cartridge magazine is, the cartridge is pulled out and inserted into the initiator cartridge chamber 15. Just before the initial position of the initiator plug 1, the tensioning hammer 4 is rotated such that the initiator plug 1 is locked against the base body 2 while the tensioning hammer 4 throws the firing pin 16 from its extreme position. The spring D 18 pushes the firing pin 16 through the pin 17 and just before the initial position the firing pin 16 strikes the firing pin 8 and charges are initiated. The flame is passed through the flame opening 21.
