RU116466U1 - DEVICE FOR DESTRUCTION OF LARGE-SIZED SPACE VEHICLES - Google Patents

Abstract

A device for destroying large-sized spacecraft, characterized in that a detonating elongated cumulative-type charge with a detonator, an igniter and a mechanism for protecting against unauthorized operation associated with the activation system is installed on the inner surface of the spacecraft body at predetermined locations.

Description

The utility model can be used in space technology to prevent large fragments of spacecraft that have exhausted their life from falling onto the ground.

A known method of cleaning near-Earth space from space objects and small particles by destroying them and a device for its implementation (see RF patent No. 2092409 with priority dated November 16, 1993)

The inventive large-sized film is launched and deployed into orbit, orienting its plane normally to the direction of flight and maintaining the tension and orientation of the film, including after impact with oncoming objects, by means of jet engines mounted on the ends of the frame sliding rods connected to the rectangular film by to its smaller parties.

This device is expensive, since it requires a special rocket to put it into orbit.

There is also known a method of destroying fragments of space debris (see RF patent No. 2204508 with a priority of 04/22/2002) consisting in the fact that an obstacle in the form of an artificial cloud consisting of fine particles is established on the route of the fragments of spacecraft. An explosive is used as the particle material.

This method is also expensive and does not provide destruction of spacecraft into predefined fragments.

The solved problem of this utility model is to ensure the separation of the spacecraft into certain fragments, which are guaranteed to burn in dense layers of the atmosphere.

The technical result is achieved by the fact that a detonating elongated charge of a cumulative type with a detonator, an igniter and a safety mechanism associated with the activation system, which allows it to be destroyed into fragments burning in dense layers of the atmosphere, is installed in the specified order on the inside of the spacecraft’s hull.

The drawing shows a diagram of a device for the destruction of large spacecraft.

The device contains a detonating elongated charge (DLD) 1 mounted on the inner wall of the spacecraft body 2, an igniter 3, a detonator 4.

In order to prevent unauthorized operation of the remote sensing system, a safety mechanism 5 with a squib 6 and a piston 7 is installed, blocking the channel 8 between the detonator 4 and the igniter 3 in the initial position.

The number of DLDs and their location depends on the required fragment sizes.

The device operates as follows: On command from the activation system (not shown), the igniter 6 is activated and the piston 7 generates a fire channel 8 by the action of gases. The detonator 4 is triggered by the next command to the igniter 3, initiating the ARD 1, and due to the cumulative effect the case material the spacecraft located under the remote sensing system is destroyed and the body is divided into fragments.
