RU2244247C2 - Method for simulation of bullet hit - Google Patents

Abstract

FIELD: methods for simulation of action of combat shots, in particular, of small arms, may be used in cinematography.

SUBSTANCE: the object is fired on from weapon by shots made in the form of capsules, which contain a filler and are destroyed at n impact. Components, whose color, dispersivity, density or physical state are selected proceeding from the possibility of provision of simulation of the preset visual effect from bullet hit in the object surface, are used as the filler.

EFFECT: simplified procedure, reduced time and expenditures connected with preparation and realization of the special effect.

Description

The invention relates to methods for simulating the effects of warheads, namely, simulating the effects of small-caliber ammunition on various objects during firing.

There are situations when the use of firearms is unacceptable. So, for example, when conducting training events with the participation of people or when shooting a feature film. In such cases - use imitating means.

In the military sports game “Paintball”, the role of firearms is played by pneumatic guns - paintball markers, and instead of live ammunition they use paint balls. Such shells are not dangerous to humans. The method of imitation consists in direct shelling of objects with shells-balls, which, hitting the target, are easily destroyed, leaving a trace of paint at the point of impact, visible in the presence of lighting. Since the game involves the participation of people, the action of paint balls is intended to simulate a bullet entering a person. The identity of the visual effect of a bullet in this game is not required.

Sometimes, for events in the absence of lighting, a phosphorescent substance is added to the filler (US 6298841). Shooting with such shells is visually similar to firing tracer ammunition. However, the effect of hitting a fluorescent projectile is similar to the effect of the action of a paintball.

Closest to the problem being solved is the method of creating visual effects, disclosed in a well-known source (Likhachev V. A. Pyrotechnics in cinema, "Art", M., 1963). This method is implemented using pyrotechnic means.

According to this source, small pyrotechnic devices, including a pyrotechnic charge and a means of initiation, are installed on the surface of the object (and, sometimes, at a shallow depth) in the place of "hit by a bullet" or along the alleged line of "firing." Upon initiation, the pyrotechnic charge is triggered and creates the necessary effect.

This method is used when shooting films not only to simulate shooting at various objects, but also to reproduce the effect of a projectile hitting a person. The universality of this method is not disputed. However, the use of pyrotechnic means is associated with the conduct of quite dangerous and labor-intensive work.

The preparation time for firing simulations for one shooting take may take several days.

The proposed method is not intended to simulate shooting at a person, but allows you to create as close to life as possible the visual effect of a firearm projectile being hit, i.e. simulate a bullet getting into various objects and materials.

The method of simulating the entry of a bullet according to the invention is carried out by shelling an object from a pneumatic weapon with shells containing a spherical-shaped capsule that collapses upon impact and a filler released when the capsule is destroyed. In this case, solid and / or liquid components are used as filler.

Since the filler does not contain dye, these shells cannot be used as marking agents.

As a pneumatic weapon for firing simulated shells, you can use paintball markers.

Objects of fire can serve various solid objects, surfaces and materials, such as soils, stones, brick and reinforced concrete walls, iron, glass, water.

The material and size of the capsules are selected depending on the properties of the surface on which it is necessary to shoot, so that when they hit the surface, the capsule is easily destroyed, releasing the filler.

The filler, its color, dispersion and density are also selected depending on the properties of the surface and on the desired effect in a particular case. So, for example, to simulate firing of firearms on a concrete surface, shells with a diameter of 17.0 mm with dispersed gray filler, such as concrete chips, on brick with a red finely dispersed component such as brick dust, on an iron surface and can be used stones - with a spark-forming component, and on water with a colorless component.

To improve the quality of the special effect, as well as regulating the speed and range, the composition of the filler can be made heterogeneous both in color, dispersion and density, and in the state of aggregation of the components used.

The way to carry out simulation work using this tool is many times simpler, safer and more economical than the known counterpart. The use of a new method of imitation in cinematography could greatly simplify the process of shooting, reducing the time and cost of preparing and implementing a special effect.
