Magazine, cartridge and method for launching a countermeasure
A magazine for storing and launching countermeasures arranged in cartridges, comprising a plurality of longitudinal cartridge cases forming the magazine, where the magazine comprises a tilting means adapted to tilt the cartridge cases, such that the openings of the cartridge cases can be directed in a selected direction, and where the magazine comprises a tracking system comprising an active position sensor adapted to detect the position of an incoming object. The advantage of the invention is that a countermeasure can be directed towards an incoming object before it is launched.
1. A magazine ( 2 ) for storing and launching countermeasures ( 5 ) arranged in cartridges ( 12 ), comprising a plurality of longitudinal cartridge cases ( 6 ) forming the magazine ( 2 ), wherein:
the cartridge cases ( 6 ) are arranged to each other in a slidable manner in a longitudinal direction,
the magazine ( 2 ) comprises a tilting means ( 25 ) configured to tilt the cartridge cases ( 6 ), such that an opening ( 14 ) of a cartridge case ( 6 ) is oriented in a selected direction, and
the magazine ( 2 ) comprises a tracking system ( 26 ) comprising an active position sensor ( 27 ) configured to detect a position of an incoming object.
2. The magazine according to claim 1 , wherein the active position sensor ( 27 ) is configured to detect the speed of an incoming object as well as the distance and the aspect angles to an incoming object.
3. The magazine according to claim 2 , wherein the active position sensor ( 27 ) is a radar based sensor.
4. The magazine according to claim 2 , wherein the active position sensor ( 27 ) is a laser based sensor.
5. The magazine according to claim 2 , wherein the active position sensor ( 27 ) is a vision based sensor.
6. The magazine according to claim 5 , wherein the magazine ( 2 ) comprises an electronic control unit ( 29 ) configured to, with the tilting means ( 25 ), control a tilting angle of the magazine ( 2 ) in dependency of a signal from the active position sensor ( 27 ).
7. The magazine according to claim 6 , wherein the electronic control unit ( 29 ) is configured to launch a countermeasure ( 5 ) in dependency of the signal from the active position sensor ( 27 ).
8. The magazine according to claim 1 , wherein the magazine comprises communication means ( 30 ) configured to transfer a signal from the active position sensor ( 27 ) to an electronic control unit ( 32 ) arranged externally of the magazine ( 2 ).
9. The magazine according to claim 8 , wherein the magazine ( 2 ) is configured to receive a launch signal from the electronic control unit ( 32 ) in order to launch a countermeasure ( 5 ).
10. The magazine according to claim 1 , wherein the magazine ( 2 ) is configured to tilt from a resting position ( 50 ) to an active position ( 51 ) in dependency of a signal from the tracking system ( 26 ) before a countermeasure ( 5 ) is launched.
11. The magazine according to claim 1 , comprising the magazine ( 2 ) comprises a fine tracking sensor ( 28 ) configured to track an incoming object detected by the active position sensor ( 27 ).
12. A tracking cartridge ( 12 ) ( 31 ) configured to be used in a magazine ( 2 ) according to claim 1 , wherein the cartridge ( 31 ) comprises an active position sensor ( 27 ) configured to detect the position of the incoming object, and communication means ( 30 ) configured to transfer a signal from the active position sensor to an electronic control unit ( 29 , 32 ) arranged in the magazine ( 2 ) or externally of the magazine ( 2 ).
13. The tracking cartridge ( 31 ) according to claim 12 , wherein the cartridge ( 31 ) further comprises an electronic control unit ( 29 ) configured to determine the position of an incoming object in dependency of the signal from the active position sensor ( 27 ).
14. A method for launching countermeasures ( 5 ) from the magazine ( 2 ) of claim 1 , the method comprising the steps of: tilting the cartridge cases ( 6 ) from a resting position ( 50 ) to an active position ( 51 ) in dependency of a signal from the tracking system ( 26 ), and launching at least one of the countermeasures ( 5 ) upon tilting of the cartridge cases ( 6 ) into the active position ( 51 ).
15. An aircraft comprising at least one magazine according to claim 1 .
