RU2616963C1 - Laser cartridge - Google Patents

Abstract

FIELD: weapons and ammunition.

SUBSTANCE: main purpose of this device is training a shooter for a fast-moving target, i.e., choosing the right lead depending on the angular speed of the target, distance to it, and the flight speed of a projectile. The laser cartridge for training in shooting small arms is mono-ray, i.e. it emits one ray, and for training in shooting hunting arms it is multi-ray imitating shot scree. The proposed laser cartridge greatly exceeds the known interactive and electronic simulators and shooting ranges by the criterion of "effectiveness-cost".

EFFECT: increasing the accuracy of training fire simulation.

Description

The invention relates to the field of training shooting from a hunting and small arms. A well-known training laser cartridge for training firing from a hunting rifle, for example, RU (11) 2221983 (13) C2. A laser cartridge is used in most electronic shooting simulators, for example, LASER - ST, PROFI.

The well-known laser cartridge does not allow the training of shooters on fast-moving targets (“fast” when the target changes its position significantly during the charge flight), since the laser beam propagation velocity is many times higher than the projectile’s flight speed, so the laser beam “hits” the target instantly after a shot, and when using a real cartridge, the target is hit with a time delay depending on the firing range and the speed of the projectile, which requires the development of skills for the shooter to take the rules th preemption.

1. The subject of the invention is a laser cartridge for firing of small arms, comprising a sleeve, a laser diode, a laser diode control unit, a sleeve with a mechanical impact element for issuing a signal to the control unit, batteries and springs, characterized in that, for the purpose of its use for training in shooting at fast-moving targets, a delay line with control elements placed on the case body has been introduced into the control unit. Control elements (bodies) must provide for setting the delay time -Tz from zero to Tz max,

Тз = 2Д / (Vо + Vд), where:

- D - firing range;

- Vo - the initial velocity of the projectile;

- Vd - projectile flight speed at firing range.

The value of Tm max obtained at maximum firing range and the value of the projectile speed at maximum range.

The values of T3, as a function of D, Vo and Vd, are calculated in advance and are set on the cartridge before firing.

2. The subject of the invention is a laser cartridge for firing a hunting rifle. The laser cartridge according to claim 1, characterized in that, in order to simulate a scree of scree, an additional 2n laser diodes with elements for adjusting the angles of their radiation are introduced into it so that the laser beams can form a cone.

In practical implementation, n≥3, and the adjustment elements should provide a change in angle from 0 to A degrees. The value of A is determined by the standard of smooth-bore gun shooting, the shooting of which is carried out on a target with a diameter of 75 cm, from a distance of 35 m, which is taken as the distance of guaranteed target destruction,

A = arg tg (0.375 / 35) = 0.6 deg.

The obtained value acts at a distance of up to 35 m. With an increase in the firing range over 35 m and up to its limit value (45-50) m, the angle A decreases in proportion to the range, and when it reaches the limit value, A = 0, so the laser cartridge can be used successfully for training bullet shooting at a range of 45-50 m or more.

Fractional charge, along with scattering, has the property of stretching along the trajectory, this feature, approximately, can be taken into account by the duration of the laser pulse, given that the magnitude of the stretching of the charge is approximately 0.1D, and the average velocity of the shot charge is about 300 m / s, for an average distance (30 m), the pulse duration will be 0.01 s.

The laser cartridge can be used in conjunction with a moving electronic target or with a screen on which a fast-moving target is displayed using a laser beam.
