Abstract

The present invention relates to a smoke missile (1) with an active smoke mass (2) for generating a camouflage fog and with a decomposing charge (3) for decomposing and igniting the active smoke mass (2). The smoke missile body (1) has a delay charge (4) which causes the decomposition charge (3) to take effect after a delay.

Description

The invention relates to a smoke throwing body according to the preamble of claim 1.

Such smoke projectiles are intended to form a fog curtain to protect vehicles or troops against detection, detection and target tracking. Usually, smoke projectiles are carried on an armored vehicle in a plurality of ejector tubes and, if necessary, ejected by igniting a propellant in a trajectory defined by the angular setting of the ejector tube. After leaving the ejector tube, the pyrotechnic active charge of the smoke throwing body is disassembled and ignited by initiating the bursting charge.

From the WO 03/106913 A1 For example, a smoke throwing device is known which has a plurality of layers of mistletoe tablets which are burnt off via a pyrotechnic active charge on the underside. As a result of the stack formation, the individual, inflamed mists of tablets burn one after the other along the ballistic trajectory of the smoke projectile. The problem here, however, is that due to the burning of the individual mist tablets successively along the trajectory of the smoke throwing body only small nets are generated. Added to this is the problem that the resulting fog wall has a comparatively low fog density.

The present invention has for its object to provide a novel smoke grenade in which in a simple manner after ejection of the smoke throwing body, the mist active mass at a predetermined distance from the object to be protected directly and without influencing incoming air to a voluminous fog wall with high fog density is distributed. This object is achieved by the features of claim 1. Preferred embodiments and further developments of the inventive smoke projectile are described in the subclaims.

The inventive smoke-impacting body has a mist-effect mass for generating a camouflage mist and a bursting charge for dismantling and igniting the mist-effect mass. Furthermore, a delay charge is provided, which causes a delayed effect of the Zerlegerladung. Due to the delay charge according to the invention, it is possible to set the mechanism for generating the camouflage already at launching the smoke throwing in motion, at the same time to shift the actual training of the camouflage to a predefined time after leaving the ejector so that the fog formation at an optimal time and so that it is at an optimal distance to the object to be protected.

The mist active mass is preferably arranged around the Zerlegerladung around. As a result, the fogging compound can be applied in a particularly effective large-volume manner upon initiation of the breaker charge. Particularly preferably, the Zerlegerladung is arranged in a longitudinal channel, which is located in the region of the longitudinal axis of the mist effective mass. As a result, a largely radially symmetrical distribution of the mist effective mass can be achieved.

The delay charge is preferably also arranged in this longitudinal channel, following the Zerlegerladung. This ensures that the delay charge in contact with the burster charge can initiate the burster charge after its burnup.

According to a preferred embodiment of the present invention, an ignition element is arranged at the end of the delay charge, which is opposite to the end of the deceleration charge facing the Zerlegerladung, which is arranged to ignite the delay charge when firing the smoke thrown. It is particularly advantageous if the delay charge comprises a deflagrative converting charge. Namely, when the delay charge is ignited at the contact point between the delay charge and the sacrificial charge opposite end of the delay charge, the delay charge burns deflagrativ with a predetermined time constant in the direction of the contact point between delay charge and Zerlegerladung. This has the particular advantage that the mechanism of mist generation can already be initiated when firing the smoke hatch, without further measures would be necessary below, such. As a signal to initiate the Zerlegerladung from the launching mechanism to the fired smoke projectile or a complex time fuse.

The bursting charge of the smoke throwing body may comprise a pyrotechnic and / or an explosive-based charge. In this case, an explosive-based bursting charge has the advantage that the fogging mass is not only very effectively ignited, but the fogging mass is also very spontaneously and large volume distributed, regardless of a distribution of fog effective mass by the air flowing into the smoke throwing body. This spontaneity of the distribution of the fogging mass can advantageously be increased even further by virtue of the fact that the fogging mass comprises a charge which converts detonatively.

In the case of the present invention, the parts which are ejected preferably dispense with metal parts, so that when the smoke thrown body is ejected, no metal parts which could lead to injuries are brought into the area of one's own troops.

An embodiment of the inventive smoke projectile is shown in longitudinal section in the accompanying drawing and will be described below.

The figure shows an embodiment of the smoke throwing body 1 with a mist effect mass 2 to generate a cloak and with a burster charge 3 for disassembling and igniting the Nebelwirkmasse 2 , The smoke-ball 1 has a delay charge 4 on which a delayed effect of the Zerlegerladung 3 causes.

The burster charge 3 is in one in the region of the longitudinal axis of the Nebelwirkmasse 2 located longitudinal channel arranged. The fog effect mass 2 is cylindrical around the burster charge 3 arranged around.

The delay charge 4 is in the longitudinal channel following the bursting charge 3 arranged. Here is the delay charge 4 with the burster charge 3 such in operative contact that when burning the delay charge 4 to the contact point between the delay charge 4 and bursting charge 3 the burster charge 3 is initiated. This active contact or the active coupling between delay charge is preferably carried out 4 and bursting charge 3 by the heat development when burning off the delay charge 4 ,

At the end of the delay charge 4 which is that of the burster charge 3 facing the end of the delay charge 4 is opposite, is a ignition element 5 arranged, which is set up, the delay charge 4 at launch of the smoke throwing body 1 to light.

About a variation of the length of the delay charge 4 between ignition element 5 and contact point between delay charge 4 and bursting charge 3 can the delay time between launch of the smoke-throwing body 1 and igniting the fogging mass 2 - And thus the removal of the camouflage nebula from the object to be protected - be defined in a defined manner. It is also conceivable, for example, for a given length of the delay charge 3 a variably adjustable delay time can be achieved that several ignition elements 5 lengthwise at the delay charge 4 are arranged. If a shorter delay time is desired, it simply becomes a primer 5 for lighting the delay charge 4 which initiates the contact point between delay charge 4 and bursting charge 3 is closer. The selection of the required ignition element 5 can be carried out automatically within the framework of a fully automated, software-supported high-speed assessment.
