Description

The invention is intended to modernize existing weapons. It can be used to increase the accuracy of firing from training, hunting, sports, game, combat and other weapons.

Known (0377579 US) is the stabilizer of the angular position of the barrel of a weapon, including a rotating body enclosed in a housing.

The main disadvantage of the known stabilizer should be the impossibility of its use on existing types of weapons, since it is assumed that it should be integrated into the weapon.

The present invention allows the use of a stabilizer in conjunction with a weapon, the development of which the presence of a stabilizer on it was not provided.

In addition, the technical result in the implementation of the invention is associated with quick fine-tuning of the stabilizer after it is installed on the weapon.

This result is achieved through the use of the following distinguishing features:

- the stabilizer is made up of two blocks;

- the first block is a gyroscope block;

- the first block is rigidly attached to the weapon, for which the housing of the first block includes a mount to the weapon;

- the second block is the trigger position sensor block of the trigger;

- the sensor unit is rigidly attached either to the tail of the trigger, or to the trigger guard;

- the second block is connected to the first via wireless radio communication, for which the first block includes a radio receiver, and the second a radio transmitter;

- both units have independent power supply.

At least one of the blocks may include a vibration sensor. The gyro unit can be arranged as follows.

It can include a housing element in the form of a frame in which a rolling bearing is mounted with a body fixed on it (for example, made of tungsten), which is supposed to be untwisted, on the other hand, the body can have an external cylindrical surface that can be fitted into a sleeve. At the end of the body (after the cuff), a coupling (for example, a bellows coupling) connected to the motor shaft can be attached to the latter.

As an electric motor, a DC voltage motor with a variable (depending on voltage) speed can be selected.

Through the control unit and the charger (working when the body is braking to charge batteries), the engine can be connected to a power source (for example, a set of batteries that provide the current and voltage required for the engine).

The case may have a connector for connecting an external charger.

The control unit ensures the stability of the voltage supplied to the motor at the specified signal parameters of the sensor unit.

For this, the control unit must include a radio receiver capable of receiving a signal from the transmitter of the sensor unit.

The control node may include a microprocessor or microcontroller.

The body of the gyroscope unit may have a radiator, a sound-absorbing inner coating, a cover, etc.

The gyro unit must be sealed (waterproof).

The part of the gyroscope unit in which the body is located must also be sealed (it is assumed that the bearing operates under lubrication conditions).

The gyro unit must have a weapon mount. For example, it can be a dovetail plank. The gyroscope unit can be attached to a weapon instead of an optical sight, an under-barrel grenade launcher, and other mounted accessories that are rigidly attached to the weapon.

An aiming device can be integrated into the gyroscope unit.

The gyroscope unit can be attached to the weapon and to a seat specially made in the last place or with the help of clamps directly to, for example, the barrel or butt (to the parts of the weapon that are motionless at the time of the shot, naturally, without interfering with moving).

The control unit may include a vibration sensor (for example, an accelerometer).

In this case, the control unit can be configured to operate in two modes - in the operating mode and in the setting mode.

The sensor unit may include a position sensor (for example, induction, capacitive - based on measuring the distance between the capacitor plates as part of one of which can be considered a trigger, optical - IR - based on the reception of radiation reflected from the trigger), a measurement unit (tester, e.g. LC meter), electrical power supply, and transmitter. In addition, it may include an analog-to-digital converter.

The sensor unit may be made contact, for example, resistive. The sensor unit itself can be mounted on the trigger guard, while the movable element of such a unit can contact the tail of the trigger.

In a non-contact version, the housing of the sensor unit must have a mounting unit to the tail of the trigger or to the trigger guard.

The constituent element of the sensor unit can be a permanent magnet (for example, neodymium), which is made with the possibility of rigid attachment to the trigger or trigger, for example, by means of a lining or glue.

The installation of a stabilizer on a weapon is, for example, as follows.

A permanent magnet is glued to the lower part of the tail of the trigger.

Holes are drilled in the trigger guard using which a sensor unit is screwed to it, for example, with an inductance coil connected to a measurement unit and connected to a magnet by a magnetic field.

In a regular place, for example, on the side rail for attaching an optical sight bracket, a gyro unit is mounted and its position is fixed on the weapon.

The work of the stabilizer.

Work mode.

By means of a control element, for example, a switch, the operating mode of the stabilizer is set. Such a control element can also be in a gyroscope unit.

Turn on the gyro unit. If necessary, turn on the sensor unit.

If the communication between the blocks is two-way (using standard wireless microcircuits), then the inclusion of the gyroscope unit can automatically lead to the inclusion of the sensor unit or vice versa.

When the gyro unit is turned on, the electric motor begins to spin the body (passive rotor of the gyro), bringing its rotation speed to about half of the maximum (for example, up to 20 thousand rpm).

When using a powerful electric motor (400 W), this will take less than 1 s with a moment of inertia of the body of 0.00014 kg⋅m ² (corresponding to the characteristic sizes of objects mounted on the weapon).

The energy of rotation of the body will be about 0.4 kJ.

By gradually pulling the trigger due to a change in the relative position of the permanent magnet and the inductor, the electrical parameters of the latter will change (it is advisable to use a flat spiral coil as a coil), which will affect the operation of the measurement unit, i.e. on its output signal, which will be supplied to the transmitter of the sensor unit.

The radio receiving device of the gyroscope unit, having perceived a change in the signal of the measurement unit, will transmit such a signal to the control unit, which, in accordance with it, will change (increase) the voltage supplied to the engine.

The engine speed will increase from the specified 20 thousand to maximum (for example, up to 45 thousand). The engine will have maximum speed immediately before the shot.

The energy of rotation of the body will be approximately 1.6 kJ (approximately the same energy has a bullet fired from AK at a distance of 100 m). Acceleration from minimum to maximum speed will be no more than 3 s.

Thus, depending on the degree of pulling the trigger, the body’s rotation frequency will change - the more the trigger is pressed, the greater it is.

Setting mode.

When working in this mode, the position of the trigger at the time of the shot is assumed to be unknown.

The control unit captures the moment of the shot with the help of an accelerometer sensitive to the vibration of the weapon during the shot, and reflects, for example, in non-volatile memory, the corresponding signal of the sensor unit.

Thus, henceforth, when working already in the operating mode, the speed of rotation of the body from minimum to maximum will change from the moment the signal of the sensor unit begins to change to a value that is defined as corresponding to the moment of the shot.

The gyroscope unit may have a control element connected to the control unit that allows you to manually set the minimum and maximum body speeds.

The minimum frequency of rotation of the body should be chosen so as to explicitly exclude low-frequency resonant mechanical vibrations during further acceleration (selected depending on the type of weapon).

In addition, the minimum frequency of rotation of the body should correspond to convenient conditions for changing the aiming object (pointing the weapon at a new aiming object).

The maximum frequency should correspond to convenient conditions for influencing the weapon to change its angular position when aiming at the same object (when changing the angular position within a few angular minutes).

When you release the trigger in accordance with the signal of the sensor unit, the control unit will begin to reduce the voltage supplied to the engine. Its rotation speed will begin to decrease. Braking the engine will lead to the generation of electricity, which can be used to recharge the batteries.

When the gyro unit is turned off, the engine rotor will stop.

When the stabilizer is off, it is possible to recharge its batteries from an external power source.
