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.

First claim

What is claimed is:

1. A decoy for protection of a fast flyer against an incoming threat and formation of a dummy target, wherein an igniter is attached to an end of the decoy and a molded body is attached to a muzzle side of the decoy, wherein the molded body is heavier than the decoy without the molded body, wherein the igniter contains a propellant charge, wherein the decoy is not driven after ejection.

2. The decoy as claimed in claim 1 , wherein the molded body is greater than 1.0 times heavier than the decoy and up to at least 1.5 times heavier than the decoy.

3. The decoy as claimed in claim 1 , wherein the molded body is twice as heavy as the decoy.

4. The decoy as claimed in claim 1 , wherein the molded body consists of tungsten or gold.

5. The decoy according to claim 1 , wherein MTV is used as a dummy target active material.

6. A fast flyer with a decoy as claimed in claim 1 .

7. The fast flyer as claimed in claim 6 , characterized by a launcher for ejecting at least one decoy and at least one warning sensor for detecting an incoming threat and for activating the launcher.

8. The fast flyer as claimed in claim 6 , characterized by a forward-directed launcher.

9. The fast flyer as claimed in claim 8 , wherein the decoy is deployed forwards at an angle to the fast flyer.

10. The decoy as claimed in claim 1 , wherein the decoy has an active material container to accommodate an active material.
