DE102011009154A1 - Method for defensive threat by dispending of camouflage smoke, involves utilizing movement grenades for discharging visual camouflage smoke effective masses before attacking unit - Google Patents

Abstract

The method involves utilizing movement grenades (19) for discharging visual camouflage smoke effective masses (18) before an attacking unit (13) that detects endangered objects endangered objects (12). A time fuse (20) is re-adjusted over a radio link (21) or wire connection (22) according to instantaneous approximation conditions of the attacking unit. An independent claim is also included for a device for applying defensive technique.

Description

The invention relates to the measures according to the two main claims.

From the EP 1 930 685 A1 It is known to equip an object on land or sea for self-protection in addition to launch tubes for defensive grenades with thrower tubes for spreading camouflage pots, as they are approximately in the DE 102 26 507 A1 are described in detail for a preferred pyrotechnic design. By temporarily sealing the acutely threatened object behind a self-built, impenetrable in the visible spectrum and an infrared sensor as a result of strongly emitting infrared spectrum oversteering, Tarnnebelwolke loses the attacker, in particular the Zielsuchsteuerung an approaching missile, the target contact; and, moreover, in the case of a non-stationary object, it can perform evasive maneuvers in the protection of its in-fumigation, that is to say no longer recognizable to the attacker.

However, there is the problem that for objects operating in convoy or otherwise composite, it is usually not possible to know in time which of them is in fact acutely threatened by the detected and now to be defended attacker. Therefore, as a precautionary measure, at least several of the objects operating adjacent to one another must fog in the event of an alarm; with the result that they are now invisible to each other, making coordinated operations at least very difficult.

In recognition of such circumstances, the present invention is based on the technical problem of ensuring, despite camouflage nebulization, the operability of endangered objects, in particular in combination; and possibly even more defense options against the current attacker to open.

This object is achieved by the features specified in the two main claims. Thereafter, the protective Tarn Nebula cloud is no longer built directly on the attacked object, but now spent from this in the direction of the attacker at a distance; namely by the camouflage-producing active mass is no longer merely spent from a mere lance, but now an ammunition with such material ammunition grenade with Luftsprengpunkt ignition device is shot against the attacker. This not only provides the advantage of preventing the target contact of the attacker at a greater distance than only when an immediate fogging is achieved, and thus also making it uncontrollable out of the final approach pathway, so to speak, purely kinematic hits unlikely; this solution also makes it possible to optimize the use of the Abwartsnarn nebula of convoy-operated objects in that the attacker of several objects and thereby under different directions overlapping, at least closely adjacent Tarnnebelwolken be pre-set, thereby, in their dense sequence , for the attacker's seeker, the more impenetrable. And because of the continuation of the Tarnnebelwolken away from the endangered objects these remain in the absence of direct fogging in undisturbed operation contact.

To place the transport grenades with the camouflage-forming active masses in front of the approaching attacker, the latter is detected by means of introduced reconnaissance and fire-control systems which are operated aboard at least some of the objects operating in the network or otherwise, for example off-site. The transport grenades can be equipped with a proximity fuse for discharging the camouflage-forming active masses. However, it is more precise and even more cost-effective to equip the transport grenades with a time fuse which is set at, or at least soon after, tube exit, taking into account the muzzle velocity and, if possible, the approach speed of the attacker to be repelled. This can be done in the air burst ammunition (ABM) introduced as such by magnetic Zeitzünderkodierung at the muzzle. In radio or wire connection to the transport grenade, the ignition point, ie the approach distance for discharging the Tarnnebelwolke as close as possible in front of the attacker, even during the approach transmitted or updated continuously. The proximity conditions can be obtained by the reconnaissance system or decentralized in at least one of the group of endangered objects and transmitted to the time fuse of the grenade, but in principle also be determined on board the transport grenade.

As a transport grenade is preferably the imported 40 mm infantry grenade with radio adjustable detonator running time, the air strike point is now placed on a predetermined point along the projectile trajectory, close to the attacker.

In addition to this so-called soft-kill effect of the invention according to the invention no longer the object itself, but as close as possible to the still distant attacker generated Tarnnebelwolke promotes a superposition of several such Tarnnebelwolken of various adjacent operating objects from a Hardkill defense with splinter or with blast defense grenades by bombardment of the attacker clearly marked by the cluster of Tarn Nebula clouds in the hemisphere.

Additional refinements and alternatives to the solution according to the invention will become apparent from the other claims and, in terms of their advantages, from the following description of a defensive scenario according to the invention in comparison to the previous use of Tarnnebelwolken. The drawing shows, in an in-scale to the function necessary abstracted sketches, with

1 a conventional Tarnnebel use in a convoy and

2 the defense method according to the invention.

A convoy 11 from endangered objects 12 , especially land or sea vehicles, gets in the sights of an attacker 13 in the form of a missile here 14 with infrared seeker 15 , That will be on board at least some of the objects 12 , or even operated by a stationary or mobile offside reconnaissance system 16 , detected.

Traditionally, the objects do 12 for the attacker 13 invisible, each by means of camouflage bodies clouds 17 to raise themselves out of camouflage mist; of what, as in 1 sketched, also still closely adjacent operating objects 12 be recorded. These are the objects 12 for the attacker 13 become invisible before or at least in its last phase of approximation; in the absence of a target, the target seek control fails, or the seeker fails 15 controls the attacker 13 into the void. However, there is no visual connection between adjacent objects 12 of the convoy 11 more. Therefore, spontaneous coordinated evasive reactions of the objects 12 out of the apparently endangered area, at least as a result of collision risks.

In contrast, after 2 the camouflage-forming active substances 18 not just by projectiles close to the objects 12 but by means of transport grenades 19 to the enlightened attacker 13 spent to. They are with Zeitzündern 20 equipped to the Tarnnebelwolken 17 now from the objects 12 distanced, namely the attacker 13 towards offset. Remaining distance and approach speed of the attacker 13 be from the separately operated reconnaissance system 16 and / or decentralized on board at least some of the objects 12 determined. The timers 20 are accordingly on magnetic coding when Rohrverlassen (not outlined) or thereafter still on radio or wire connections 21 . 22 adjusted or readjusted so that the Tarnnebelwolken 17 now, inevitably slightly offset, each other more or less overlapping immediately before the attacker 13 form. This leads to a desirable increase in the density of the resulting Tarnnebelwolke 17 ; while coordinated operations of the objects 12 no longer be affected by their foggy environments.

The effect of the use of camouflage nebulae to protect objects that are in acute danger in asymmetric combat scenarios 12 against an identified attacker 13 So it increases when the objects 12 no longer self-fogging, but now according to the invention by means of transport grenades 19 overlapping Tarn Nebula clouds 17 immediately, at least as close as possible, in front of the seeker's head 15 a distantly detected attacker 13 be raised. Such a for the seeker 15 practically impenetrable cluster of clouds of relatively low but deliberately spent Nebelwirkmasse 18 can then also as a target for hard-kill defense measures by the endangered objects 12 themselves or on the part of combat stations accompanying them. Above all, however, remain by such laying the Tarnnebelwolken 17 from the objects to be protected 12 away the view at the objects 12 and thus also the visual connection between in the composite - in a convoy 11 - operating objects 12 unobstructed and therefore, as a result of always good view of the surrounding conditions, the position control fully maintained even under camouflage fog.
