Description

FIELD OF TECHNOLOGY

The claimed technical solution relates to the field of weapons, specifically to devices for testing ammunition by throwing while checking the operation of the fire chain of contact fuses of shells and missiles.

BACKGROUND

Checking the operation of contact fuses of shells and missiles in most cases is carried out by firing on the ground, which in addition to significant costs creates difficulties in firing and evaluating the results. This is due to the need to fix the angles of the projectile’s meeting with the surface of the firing range (especially for fuses with a side-mounted device), specially prepare the firing range to avoid rebounding.

Known methods for testing the units of artillery shells by throwing (Karpov P.P. Initiation means: Textbook - KKAP: OBORONGIZ, 1945. P. 2-53. Karpovsirl945.djvu). Devices for such tests are provided in OCT B84-1098-75 “Mechanical and Electromechanical Products. Casting test methods "

The closest analogue (prototype) is a type II stand for testing products by casting according to method A according to OCT B84-1098-75.

The type II stand consists of a lifting device 1, column 2, a guiding device 3, a control panel 4, an obstacle 5, a load (object) 6, a device for hanging and throwing 7. When dropped to test the operation of a contact fuse, it is rigidly attached to the load 6, a cast object is created. After lifting the object to a predetermined height, the device for hanging and throwing 7 releases the object and it falls along the guiding device 3 onto the obstacle 5, which is installed at a given angle of meeting with the fuse.

The disadvantage of this technical solution is that with a large lifting height of the cargo (3-10 m) and the mass of the cargo exceeding the mass of the fuse by 100-1000 times, the guide device, usually made in the form of a steel pipe, the diameter of which is several times more than the diameter of the tested fuse to ensure free fall of the load, due to the "yaw" of the protruding end of the fuse, the accuracy of the angle of the meeting with the obstacle is not ensured. This is especially often manifested at small angles of encounter with an obstacle, imitating the rebound phenomenon. The design of the guide device, which provides more accurate movement of the object during a fall, greatly complicates its design and operation.

The problem to which the claimed technical solution is directed is to create a simple device that ensures, when throwing, the accuracy of the angle between the fuse and the obstacle.

This problem is solved due to the fact that the barrier is rigidly connected with an additional guide tube, slightly exceeding the maximum diameter of the fuse in internal diameter, and the fuse with an additional sleeve mounted on it as a shank directed towards the load is suspended inside the additional pipe and held on the level of the end of the pipe due to the stoppers until the moment of meeting with the load, which freely falls along the guide device; however, after meeting with the barrier, the sleeve protrudes above the end of the additional pipe, preventing the pipe end from touching the load. The length of the additional pipe is selected based on the possibility of installing the fuse in the initial position under the lower end of the guiding device (or its opening part) and removing the device or cargo after being dropped.

At small angles between the fuse and the obstacle (more than 20 °, characteristic of the occurrence of a “rebound”) at a distance of 5-15 mm from the projection onto the obstacle of the contact surface of the fuse on the obstacle from the side of the smallest surface rise, a collar is made.

The technical result of the utility model is to ensure the accuracy of the angle of the fuse with the obstacle due to the fact that the fuse moves in an additional pipe strictly vertically due to the small clearance between the fuse body and the pipe and the insignificant travel along the pipe from the initial position to the obstacle. At the same time, the fuse receives the moment of inertia necessary for the operation of the side-by-side mechanism, and when hit by an obstacle, a load of a given mass acts on it.

The design of additional units of the device is extremely simple and does not cause technical difficulties in execution.

DISCLOSURE OF A USEFUL MODEL.

The utility model is illustrated by a description and a drawing (Fig. 1).

The device consists of: a lifting device 1, a column 2, a guiding device 3, a control panel 4, a barrier 5, a load 6, a device for hanging and throwing 7, an additional guide tube 8, rigidly fixed to the barrier, an additional sleeve 9, fixed from the side the fall of the load on the fuse 10, which is held at the end of the pipe due to the stoppers 11 until it encounters a load 6 freely falling along the guiding device 3. The surface of the barrier 5 is made at a predetermined angle of the fuse with the barrier. If necessary, a bead is made on the barrier.

IMPLEMENTATION OF A USEFUL MODEL.

The fuse 10, inserted into the pipe 8, is held at the end of the pipe by stoppers 11 made, for example, in the form of copper wires inserted into the holes in the sleeve 9. The load 6 rises to a predetermined throwing height and, after the device for hanging and throwing 7 is triggered, falls along the guide the device 3 onto the sleeve 9. When the stopper 11 is hit, the fuse 10 with the sleeve 9 receives the acceleration of the load 6 and, together with the load, falls vertically onto the obstacle 5. Thus, the fuse receives acceleration and the accuracy of the angle meeting with an obstacle at a rather simple addition of existing test bench for throwing weapons.
