The invention relates to practice ammunition including a marking agent.
In the use of practice ammunition of this kind—such as practice shells and practice bombs—it is important to mark the impact site so as to obtain optimum practice results. To this end, the practice ammunition comprises a head with a chamber containing a marking agent, preferably a powder with a reddish color. The head is made of a material which when striking a target will burst and release the colored powder. The powder is scattered within some radius about the impact site, thus marking the latter optically. However, the colored powder is visible only under conditions of sufficient brightness; under low light or at night it will not be visible unless powerful night viewing equipment is used.
The U.S. Pat. No. 5,018,450 discloses a practice projectile in which the marking agent is contained in a burstable hood at the head of the practice projectile. The marking agent has chemical components contained in separate frangible compartments which are mixed and react chemically as the compartments burst when the practice projectile strikes its target, this chemical reaction causing the optical marking to be produced. A practice projectile of this kind will make its impact visible at night as well.
The German Patent Publication No. DE-AS 11 99 660 discloses a practice projectile to be fired from a barrel-type weapon and also having a marking agent comprising chemical components contained in a plurality of separate frangible compartments. In this projectile, these compartments are designed to burst when the projectile leaves the muzzle. This will cause the practice projectile to come apart and to eject from the muzzle of the barrel a mushroom-shaped cloud of smoke visible from a great distance. The firing of live ammunition will thus be simulated in a more realistic manner.
It is a principal object of the present invention to improve upon a practice ammunition projectile of the type described above including a chemically reactive marking agent, and to enable its trajectory to be observed, if desired.
This object, as well as further objects which will become apparent from the discussion that follows, are achieved, in accordance with the present invention, by providing compartments for the chemical components, which are adapted to be broken up by the initial acceleration forces and/or the centrifugal forces applied to the projectile when it is fired, and by providing a hood, surrounding the compartments, which is formed of optically transparent material to enable the trajectory of the practice projectile to be tracked.
In accordance with the invention, the compartments containing the chemical components are broken up as early as in the initial and/or the twist acceleration phases. The compartments are individually contained in a hood made of an optically transparent material and located at the head of the practice projectile. On impact, the hood will burst and release the marking agent to identify the impact side. At the same time, the optically transparent hood enables the marking—such as the chemoluminescent effect of the chemically reacting components—to be perceived along the entire trajectory of the practice projectile. The chemical components are selected to produce a sustained luminous effect lasting for an extended period of time, enabling the practice projectile to be optically tracked along its entire trajectory, and additionally to mark the impact site.
The duration of the chemical reaction, as well as the frequency and the brightness of the emitted light, may be adjusted within broad ranges by properly selecting the chemically reactive components. The reaction preferably produces sustained luminous effects so that the trajectory of the practice ammunition may be optically tracked, and so that the impact site will be marked.
The present invention preferably uses starting materials which, when chemically reacted, emit light in the visible or infrared ranges. If emitted in the infrared range, the marking light may be observed with night viewing equipment.
Swiss Patent No. CH 381 565 discloses a practice projectile comprising a transparent hood at the head thereof which will burst on impact, such hood containing a marking material such as a colored powder. However, this optically transparent hood is intended only to recognize the color of the powder so as to distinguish various types of projectiles, such as practice projectile and live ammunition. It is not possible with like designs to track the trajectory of the projectile.
For a full understanding of the present invention, reference should now be made to the following detailed description of the preferred embodiments of the invention as illustrated in the accompanying drawings.
The preferred embodiments of the present invention will now be described with reference to
When the partition is broken up by the force of the acceleration generated during firing, for example, the chemical reaction of the two chemical components causes chemoluminescent light to be emitted which is visible through the transparent hood while the projectile is flying. On striking the target, the hood bursts, causing the end products of the reaction to be scattered in the vicinity of the impact site, whereby the emitted light marks that site optically and is visible from great distances.
There has thus been shown and described a novel practice ammunition projectile which fulfills all the objects and advantages sought therefor. Many changes, modifications, variations and other uses and applications of the subject invention will, however, become apparent to those skilled in the art after considering this specification and the accompanying drawings which disclose the preferred embodiments thereof. All such changes, modifications, variations and other uses and applications which do not depart from the spirit and scope of the invention are deemed to be covered by the invention, which is to be limited only by the claims which follow.
