DECOY

Abstract

The invention relates to a decoy (3) for protecting a fast aircraft (1) against an incoming threat (2), wherein said decoy is non-driven. The decoy (3) has a squib (6) on one end and a molded body (11) on the opening side. If the decoy (3) has an active material container (8), the squib (6) can be attached to the end side thereof and the molded body (11) attached to the opening side thereof. The squib (6) contains a propellant, which is converted into a drive energy. The molded body (11) is heavier than the decoy (3) without the molded body (11) and has the task of preventing the separating of the molded body (3) to the rear. In addition, the molded body (11) should be at least 1.0-1.5 times heavier than the decoy itself. Advantageously, however, the molded body (11) is twice as heavy.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The invention will be explained in more detail based on an exemplary embodiment with a drawing. In the figures:

[0021] FIG. 1 shows a schematic representation of a typical deployment scenario of an aircraft with a dummy target,

[0022] FIG. 2 shows a slightly transparent representation of the dummy target before firing with the essential components,

[0023] FIG. 3 shows a representation of the dummy target from FIG. 2 after firing.

DETAILED DESCRIPTION

[0024] A fast-flying aircraft (fast flyer) 1 is shown in FIG. 1. This representation in FIG. 1 shows the view from a threat 2, in this case the view from a search head.

[0025] To ward off this threat, after detection a decoy 3 is deployed against the threat to simulate a dummy target 3. For this purpose, the fast-flying aircraft 1 has at least one launcher 4, which is designed to be able to eject the decoy 3 forwards in the direction of flight of the fast flyer 1. At least one warning sensor 5 is envisaged as a detection sensor, which detects the incoming threat 2 and activates the launcher 4 or the protection system, which counters the threat 2 with the decoy 3. Due to the property of this decoy 3 and the mode of action of the threat 2, the threat 2 perceives this decoy 3 as a more attractive target and switches to this dummy target 3. The decoy 3 is deployed forwards relative to the aircraft at an angle, preferably in a solid angle to the fast-flying aircraft 1 (FIG. 1).

[0026] The structure of the decoy 3 is shown by FIGS. 2 and 3.

[0027] The decoy 3 comprises an igniter 6, which is attached at the end to an active material container 8 of the decoy 3. For safety reasons, a tube sensor 7 is provided between a sabot 10 and the igniter 6. The active material container 8 is used in turn to accommodate an active material 9.

[0028] At the front or on the muzzle side, a molded body 11 is integrated on the active material container 8. The molded body 11 attached to the active material container 8 on the muzzle side is of a solid construction. The weight of the molded body 11 is greater than the weight of the decoy 3 without the molded body 11. As a rule, the molded body 11 for fast-flying aircraft should be at least 1.0-1.5 times what the decoy 3 would weigh without molded body 11. In practice, it has been shown to be sufficient if the molded body 11 is twice as heavy as the decoy 3 itself without the molded body 11. The molded body 11 can preferably consist of tungsten.

[0029] The molded body 11 and the igniter 6 or the propellant contained therein are coordinated with each other in such a way that the expected recoil is precisely adjusted.

[0030] FIG. 3 shows the decoy 3 shortly after ejection from a launch tube of the launcher 4 that is not shown in detail. With the ignition of an ignition charge (propellant) in the igniter 6, the decoy 3 receives a power input, i.e. a driving force that not only drives it out of the launch tube of the launcher 4, but counteracts a recoil pulse that usually occurs during launch and thus does not allow it to arise. The decoy 3 acted upon by this surplus impulse moves in front of the fast-flying aircraft 1 as a result of the impulse, wherein in this phase the decoy 3 becomes a dummy target 3. For this purpose, the tube sensor 7 releases the ignition channel, which is not shown in detail, wherein the active material 9 is ignited and the dummy target 3 forms.

[0031] The expansion of the dummy target 3 is perceived by the threat 2 as a target, as it is set up in the direction of the fast-flying aircraft 1. The active material 9, in turn, lights up for so long that the threat 2 can no longer lock on to the fast-flying aircraft 1 when it flies past the dummy target 3.
