Description

The invention relates to a multi-barreled drum gun with rotary barrel barrels.

While conventional recoilless weapons are effective in neutralizing the recoil force generated during ignition, but fail because they are not able to bring about an automatic ignition at high speed. This deficiency stems from the relatively long length of recoilless ammunition that is necessary to achieve the take up additional propellant, which develops the forward haul and for the multi-stage ignition cycle usual automatic weapons is necessary. The need to axially ram each projectile into the ignition chamber and axially pulling the used cartridge case out of this, coupled with the relatively large overall length of the normal recoilless ammunition projectile, allows any automatic high-speed fire to

S09S17 / 0445

- Eliminate 2 free weapons.

A certain step towards this technical development has been made with the so-called open chamber locking mechanism done as described, for example, in US Pat. No. 3,041,939.

In general, such an open-chamber gun is distinguished by an open-chamber locking mechanism a locking frame with a chamber containing a rotating cylinder with one or more ignition chambers, which are open laterally through the circumference and longitudinally through the front end of the cylinder. The cylinder is mounted on the locking frame for rotation or swinging movement to sequentially each ignition chamber in an ammunition feed position, an ignition position and, after ignition, a shell-less ammunition in a cartridge case ejector position bring to. In the insertion position, the open side of the ignition chamber is on the side Ammunition insertion opening aligned in the breech frame to allow a lateral insertion movement of an ammunition projectile into the chamber. In ignition position the ignition chamber is closed by the locking frame and open to the front of the projectile borehole to the Prepare locking mechanism for firing the projectile in the chamber. The ejector is in the open side of the ignition chamber aligned with a side ejector opening in the breech frame to a side Allow the spent cartridge case to be ejected from the chamber after ignition. A primary benefit of one Open-chamber locking mechanism consists in its effective two-stage ignition cycle with an initial lateral

809817 / QA4S

Infeed movement of each ammunition in the ignition position and finally the lateral ejection of each spent cartridge case from the ignition position. consequently that is Total path of each ammunition through an open-chamber locking mechanism from insertion "to ejection regardless of but equal to a fraction of the total length of the projectile and is substantially smaller than the entire ammunition path through a conventional closed-chamber locking mechanism. In an open chamber gun with a fixed barrel, each launch tube is attached to the breech frame and remains stationary on it, | and each firing chamber is stationary aligned with the gun barrel during firing.

In contrast, according to the invention, a drum gun is intended be developed in such a way that an actual recoil-free ignition operation is possible with a high ignition sequence is, with the recoil force neutralized and an automatic ignition at high speed without that additional propellants would be required in the ammunition is brought about.

This is achieved according to the invention characterized in that the rotary tube runs connected to the closure frame support _S ind (and the carrier is designed to rotate in the closure frame chamber, such that the ignition chamber can be brought into an ammunition loading position, a firing position in which the open side of the ignition chamber through the closure frame is closed and the ignition chamber is open forward to the bore in the gun barrel, such that a high pressure propellant is generated in the ignition chamber; and that passage means connect this ignition chamber and a venturi device open to the rear in the ignition position, such that a part

609S17 / 0U5

dee propellant gas at high speed through the venturi device escapes while the ammunition is firing and a counter-reverse thrust on the gun, the same and in the opposite direction the recoil force that the gun experiences during ignition.

The passage devices preferably have a calming cam on, which is in the longitudinal direction by at least one of the elements, shutter frame or shutter frame carrier extends and is laterally open in the ignition chamber in the ignition position.

It is useful in one of the parts of the gun, breech frame element and a carrier element rotatable in the closure frame element, a venturi device which is open to the rear is provided, which is open through the rear end of the ignition chamber in the ignition position, so that a part of the propellant gas at high speed exits through the venturi device and a counter reverse thrust at the gun essentially the same and opposite of the return force exerted on the gun during ignition.

The closure frame according to US Pat. No. 3,041,939 and thus the cylinder chamber, on the other hand, is in the rear end closed by an end wall, whereas according to the invention the cylinder is closed by a rear opening in the closure frame exposed and the cylinder chambers are open to the rear against Venturi passages, which in turn are through the rear end of the cylinder are open, so that during the firing of ammunition in the rotary cylinder part of the Propellant gas is expelled backwards from the cylinder during the firing process to generate a counterforce.

- 5 -609817 / 0-U5

The venturi devices on the closing frame that open to the rear and that are in connection with the ignition chamber stand, allow some of the high pressure propellant gas to pass through the venturi devices at high speed derive and trigger a back-up thrust on the gun, which is essentially the same and opposite to the return force exerted on the pipe.

Ignition chambers and venturi devices can be installed via Ireibgas calming rooms are in connection, which extends in the longitudinal direction through the locking frame and extend the cylinder and laterally with the ignition chamber through the openings in the inner wall of the ignition bracket and the side walls of the Zündkamner are in connection.

It should be recalled at this point that with the reverse milling open chamber gun according to the invention jacketed, semi-flammable and caseless ammunition can be ignited. It should be in this In connection with the aforementioned patents, in which various types of ammunition 3 and reference were made to the related patent applications
