TARGET MARKING MUNITION

MUNITIONS A MARQUAGE DE CIBLE

English Abstract

In order to mark the point at which a projectile (10, 11) strikes a target, a container (3) that holds an agent to mark the target is incorporated into the ogive area of the projectile (10, 11). When the projectile (10, 11) strikes the target, the container (3) is broken so that the marking agent can escape through holes (2) made in the ogive (4) or the rear section. In order that the marking agent can escape in this form, an over-pressure is generated within the projectile (10, 11). This can be done by a gas cartridge (7) with a release mechanism (8) or by a plunger (9).

French Abstract

Pour marquer le point auquel un projectile (10, 11) frappe une cible, un contenant (3) renfermant un agent destiné à marquer la cible est incorporé dans la zone ogivale du projectile (10, 11). Lorsque le projectile (10, 11) frappe la cible, le contenant (3) se brise afin que lagent de marquage puisse séchapper par des trous (2) pratiqués dans logive (4) ou la partie arrière. Pour que lagent de marquage puisse séchapper sous cette forme, une surpression est générée à lintérieur du projectile (10, 11). Cela peut être accompli au moyen dune cartouche de gaz (7) comportant un mécanisme de libération (8) ou par un plongeur (9).

Target Marking Munition
The present invention relates to a target marking munition, in particular for
mortars
and artillery.
Because of the use of training munitions that mark targets by pyrotechnic
means
(hot, burning particles) or if live munitions such as high explosive, smoke,
and
illuminating munitions, are used, there is a danger that fires, in particular
ground
fires, will be started. So-called forest fires in the area also play a role in
such
situations.
In order to conduct exercises in areas of this kind, inert projectiles that
have no
teiminal effect are used. This is problematic, particularly in the case of
target
practice that involve observers in the area of the target, since it is
impossible or
extremely difficult to locate the point of impact of the projectile. Thus it
is made
difficult for the observer to report back to the weapon crew and enable them
to aim
the weapon.
DE 10 2005 053 Al describes a projectile that marks the point of impact. This
training projectile has a hollow ogive that accommodates a first, chemically
inactive
and a second, chemically active marking agent. The first marking agent
generates a
colour effect, and the second marking agent generates a light effect. The
ogive itself
must burst in order for this to happen.
It is the objective of the present invention to create a munition that marks
the point
of impact in a simple manner by temporary visual marking.
The present invention is based on the idea that in order to mark the point of
impact
of a projectile at a target, a container (3) is incorporated in the ogive area
of the
1

projectile. This container holds an agent to mark the target. When the
projectile strikes the
target, the container is broken so that the agent that marks the target can
escape through holes
in the ogive or in the rear of the projectile. In order that it can escape in
this form, an over-
pressure is generated within the projectile. This pressure can be generated by
a gas cartridge
with a release mechanism, or by a plunger or the like.
The body of the projectile incorporates a plunger or a gas cartridge that
generates internal
pressure when the projectile impacts and a liquid that is preferably
luminescent is expelled
through holes. This liquid is characterized in that it can be used for marking
targets by day or
by night.
The plunger is displaced either by the gas cartridge or mechanically by
deformation
(preferably defined), axially to the build-up of the internal pressure. The
gas cartridge is
punctured by a release mechanism that is, in its turn, punctured directly when
the projectile
impacts or by a detonator. The container that holds the liquid releases the
liquid through holes
in the ogive or in the base of the projectile so as to mark the target. The
mass, which is
preferably luminescent, is released without pyrotechnic means or damage to the
body of the
projectile with the fragmentation. The defined deformation of the plunger can
be effected by a
detonator that is incorporated in the base of the projectile.
The advantages are that there is no more danger of fires being started and
that the visibility of
the wreath-like point of impact is good in both daylight and in darkness,
without the need to
generate colour marking and a light effect. Furthermore, fragmentation of the
ogive is not
necessary. The projectile is simple and safe to handle and is the ballistic
equivalent of existing
projectiles.
In some embodiments, there is provided a projectile with a tracer substance
for marking the
impact point of the projectile on a target, at least one container being
integrated in the ogive
region of the projectile containing at least one means for marking the target,
and the container
being destroyed as the projectile impacts the target, wherein the means for
marking emerges
via bores introduced in the ogive or in the rear region, for which purpose
overpressure is
generated in the projectile, wherein the container is destroyed by a gas
cartridge located in
2

front of it that is pierced by the trigger mechanism, and the gas cartridge
generates the
overpressure.
In some embodiments, there is provided a projectile with a tracer substance
for marking the
impact point of the projectile on a target, at least one container being
integrated in the ogive
region of the projectile containing at least one means for marking the target,
and the container
being destroyed as the projectile impacts the target, wherein the means for
marking emerges
via bores introduced in the ogive or in the rear region, for which purpose
overpressure is
generated in the projectile, wherein the container is destroyed by a piston
located in front of it,
the piston generating the overpressure.
The present invention will be described in greater detail below on the basis
of embodiments
shown in the drawings appended hereto. These drawings show the following:

Figure 1: a projectile with a gas cartridge, in cross section;
Figure 2: a projectile with a plunger, in cross section.
Figure 1 shows a projectile 10, in this instance a training mortar bomb, with
a gas
cartridge 7 and release mechanism 8 for the cartridge 7 in a stylized cross
section. A
detonator bears the number 1. One hole, or preferably a plurality of holes, is

numbered 2, and a container is numbered 3. In this case, the container 3 holds
a
liquid. This is enclosed by an ogive 4 that protects the complete system and
also
accommodates an inert mass 5 that serves to ensure ballistic equivalence.
Within
the rear section 6, as in a mortar bomb, there are various holes through which
a
propellant charge (not shown in detail herein) is ignited.
It is preferred that the holes 2 be spaced equidistantly around the periphery
of the
ogive 4 or in the rear section of the projectile.
Figure 2 shows another projectile 11 that is also a practice mortar bomb that
instead
of the gas cartridge 7 and release mechanism 8 incorporates a plunger 9. These

function as follows:
When the projectile 10 or 11 impacts, the shock generated by the impact causes
the
gas cartridge 7 with the release mechanism to be punctured or the plunger to
be
moved. The liquid container 3 is destroyed by the over-pressure within the
projectile 10, 11. The liquid contained therein, which is preferably
luminescent,
mixes as it leaves the ogive 4 through the holes 2. As a result of this, the
target
within the target area is marked for all practical purposes simultaneously as
the
projectile 10, 11 impacts and is thereby indicated to an observer (not shown
herein).
A detonator is incorporated in the rear area of the ogive 4 so as to assist
the function
of the gas cartridge 7 or the plunger 9.
