RU2584183C1 - Catcher for models of missiles - Google Patents

Abstract

FIELD: sport.

SUBSTANCE: invention relates to bench equipment used for collection of models of missiles at development of underwater start. Said task is solved by fact that proposed invention is used catcher consisting of two sections: top and bottom. Lower section consists of metal frame, on which there are several layers of wooden boards with metal sheets, folded in form of tiles. Layers are spaced apart in height by means of wooden frames arranged along perimeter of each layer. Upper section is mounted on supports mounted on lower section, and consists of metal frames with fixed on them metal elastic net. Between metal frames there is high-strength woven material. Number of layers on lower section and metal frames with mesh top section are determined depending on dynamic and weight and dimension characteristics of models. For determination of firing accuracy to metal frame lower section target made of woven material with marking applied on it is attached.

EFFECT: technical result consists in improvement of reliability of catcher using high-energy models projectiles and possibility of determination accuracy of fire.

Description

The invention relates to bench equipment used for catching mock-ups of rockets when practicing underwater launch.

The well-known "Trap for a high-speed aeroballistic model with the test material" (RF patent No. 98238, F41J 1/08), made in the form of a barrier of three sections mounted across the direction of movement of the model, the first of which is equipped with screens made of plastic film with air gaps in the longitudinal direction, the second is filled with fluffy tow, and the third is filled with polyethylene granules.

The disadvantages of this device are:

- the impossibility of catching a mock-up of a rocket projectile having high-energy characteristics, since having a significant supply of kinetic energy, the mock-up easily overcomes this barrier;

- lack of a target, which does not allow to determine the accuracy of shooting.

The objective of the proposed technical solution is to develop a catcher for high-energy models of rockets.

This problem is solved by the fact that in the present invention uses a catcher, consisting of two sections: lower and upper. The lower section consists of a metal frame on which several layers of wooden boards with metal sheets are laid. Metal sheets are folded in the form of tiles. The layers are spaced apart in height using wooden frames installed around the perimeter of each layer. Separation of layers is necessary to eliminate projectile rebound due to the fact that when introduced into the first layers of the lower section of the catcher, the projectile acquires a steady direction of movement until it stops completely. The upper section is mounted on supports installed on the lower section and consists of metal frames with an elastic metal mesh fixed on them (such as a panzer net or netting net). Between the metal frames, a high-strength woven material (such as rubber tarpaulin) is laid. The number of layers on the lower section and metal frames with a mesh of the upper section are determined depending on the dynamic and mass-dimensional characteristics of the layouts.

To determine the accuracy of shooting, a target made of woven material with markings applied on it is attached to the metal frame of the lower section.

In FIG. 1 shows a catcher for models of rockets.

The catcher consists of the lower 1 and upper 2 sections. The lower section consists of a metal frame 3, on which layers of wooden boards 4 with metal sheets 5 are laid through a wooden frame 6. A target 7 is attached to the metal frame 3. The upper section is mounted on supports 8 and consists of several layers of metal frames with a net 9. Between woven fabric 10 is laid in frames. FIG. 2 shows the target 7 bottom view of the catcher.

The proposed device operates as follows:

- missile mock-up is placed in the test bench and lowered under water to the depth of launch;

- after launch, a mock-up of a missile pierces the target 7, enters the lower section 1 of the trap and is inhibited by layers of wooden shields 4 with metal sheets 5;

- depending on the depth of launch, the mock-up of a missile afterwards may have sufficient speed to overcome the lower section, so the catcher has an upper section 2 consisting of several layers of mesh 9 and strong fabric 10 for the final damping of the layout speed due to the elastic and strength properties of the barrier.

- on the metal frame 3 of the lower section 1 is mounted target 7 with which the accuracy of fire is determined.

The design of the trap makes it possible to reliably rescue a prototype of a missile launching from under the water, and after performing a defect, use it again, replacing the broken metal sheets of the trap, which reduces material costs for working out.

Claims (2)

Catcher for mock missiles when practicing underwater launch, made in the form of a barrier installed in the transverse direction relative to the flight path of the layout, characterized in that the barrier is made of two successively installed sections, the lower of which is a metal frame onto which several layers of wooden boards with metal sheets are laid through a wooden frame, and the upper one is mounted on supports installed on the lower section, and consists of layers of metal frames with fastening on them of elastic mesh, which is located between the high-strength woven fabric. 2. A catcher according to claim 1, characterized in that a target made of woven material with markings applied to it is attached to the metal frame of the lower section.
