Description

The invention relates to the field of military equipment, namely to rockets with detachable or cluster warheads, and can be used to develop devices for separating or opening the warheads of rockets of a wide range.

To successfully deal with many ground targets, rockets are now widely used, equipped with autonomous flight control systems, from which signals can be used to separate monoblock or open cluster warheads of rockets.

Known control systems containing accelerometers, calculators and actuators of the compartment, providing the formation of teams for the separation (opening) of the warheads of missiles (see, for example, Nikolaev Yu.M., Solomonov Yu.S. "Engineering design of guided ballistic missiles with solid propellant rocket engines", M .: Military Publishing House, 1979, pp. 14-20), taken as an analogue.

The objective of this technical solution-analogue was to increase the accuracy of shooting compared to unguided shells.

A common feature with the proposed by the authors of the device for forming the time of opening or separation of the head part is the presence of the executive mechanisms of the Department.

The most general in technical essence and technical result achieved is a missile guidance device built on the basis of a satellite navigation system (see Military Review magazine dated 10.22.11, article “No matter what the shot is, everything is aimed at you!”) (Military website Review ”of 10.22.11, the article“ Whatever the Shot - Everything Is Aim! ”, topwar.ru/7853-chto-ni-vystrel-vse-v-cel.html), taken as a prototype that contains a navigation module as part a shell with a GLONASS signal receiver.

The device adopted for the prototype operates as follows. Shells are fired at targets with known coordinates. In flight, the receiver of the navigation module continuously receives the current coordinates of the projectile, on the basis of which the magnitude of their mismatch with the coordinates of the target is determined, which serves as a control signal for the aerodynamic rudders.

The objective of this technical solution (prototype) was to increase the accuracy of firing a projectile by continuously pointing it to a target using aerodynamic rudders.

The reasons that impede the achievement of the technical result indicated below when using the known device adopted for the prototype include the loss of the required accuracy of projectile guidance in the event of separation or opening of its warhead over the target.

Common features with the invention in the prototype device is the presence of a GLONASS signal receiver, etc.

Unlike the prototype, in the proposed device, the GLONASS or other satellite navigation systems signal receiver is equipped with a unit for subtracting the current coordinates of the projectile from the set coordinates of the separation point or opening the head, and the output of the subtraction unit contains a difference signal generator with a threshold element that is electrically connected to the separation executive mechanism, moreover, the trigger condition of the threshold element is determined by the ratio:

| Δx | ≤ε,

where | Δx | - the magnitude of the difference signal;

ε is the marginal error in determining the current coordinates of the projectile by the receiver of GLONASS signals or other satellite navigation systems.

This allows us to conclude that there is a causal relationship between the totality of the essential features of the claimed technical solution and the achieved technical result.

These signs, distinctive from the prototype and to which the requested amount of legal protection applies, are sufficient in all cases.

The objective of the invention is to provide a device for forming the time of opening or separation of the head of a rocket, providing high accuracy of opening or separation of the head over the target due to the use of the shell of the receiver of GLONASS signals or other satellite navigation systems and an electrical circuit for processing them.

This is achieved by the fact that in the device for forming the time of opening or separation of the warhead of the rocket containing the actuator opening or separation of the warhead and the GLONASS signal receiver with the possibility of pre-setting the coordinates of the separation or opening of the warhead in it, according to the invention, the GLONASS or other signal receiver satellite navigation systems is equipped with a unit for subtracting the current coordinates of the projectile from the set coordinates of the separation point or opening of the warhead, and the output q the subtraction unit contains a differential signal driver, with a threshold element electrically connected to the actuating mechanism of the compartment, and the trigger condition of the threshold element is determined by the ratio:

| Δx | ≤ε

where | Δx | - the magnitude of the difference signal;

ε is the marginal error in determining the current coordinates of the projectile by the receiver of GLONASS signals or other satellite navigation systems.

The device operates as follows.

Before starting, the coordinates of the point of opening or separation of the missile head are set in the GLONASS signal receiver or other satellite navigation systems. Launch a projectile.

In flight, the current coordinates of the missile are subtracted from the established coordinates and the value of the difference signal is determined. As soon as this value falls within the instrumental error of the GLONASS receiver or other satellite navigation systems, an electric impulse is applied to the actuating mechanism for opening or separating the head part and the head of the shell is separated or opened over the target.

Conducted flight tests of rockets with the proposed device confirmed its performance (the possibility of its use) and high accuracy of formation of the moment of separation or opening of the warhead.
