Abstract

A dispenser for storing and launching countermeasures from an aircraft, comprising an elongate body provided with at least one launch opening where the countermeasures are stored in cartridges, where the cartridges are interconnect to each other in a slidable manner, and where the cartridges are adapted to be tilted by a tilting means to a selected angle, such that the openings of the cartridges can be directed in a selected direction. The advantage of the invention is that a countermeasure can be directed in a desired angle before it is launched.

First claim

The invention claimed is:

1. A dispenser ( 2 ) for storing and launching countermeasures ( 5 ), comprising an elongate body ( 8 ) provided with at least one launch opening ( 10 ) and configured for storing the countermeasures ( 5 ) in cartridges ( 12 ), wherein:
the dispenser comprises a plurality of cartridges ( 12 ) forming a magazine ( 11 ), wherein each cartridge comprises an opening ( 14 ) and a center axis ( 15 ),
the dispenser is configured to be mounted on an aircraft ( 1 ) with a longitudinal direction of the elongate body ( 8 ) essentially coinciding with a direction of motion of the aircraft ( 1 ), wherein the cartridges ( 12 ) are arranged to each other in a slidable manner in a direction coinciding with the center axis ( 15 ), and
the cartridges ( 12 ) of the magazine ( 11 ) are configured to be tilted by a tilting means ( 20 ) in a selected angle with reference to the direction of motion of the aircraft ( 1 ) and dependent on the relative azimuth and elevation angle to an incoming threat, such that the openings ( 14 ) of the cartridges ( 12 ) are oriented in a selected direction.

2. The dispenser according to claim 1 , wherein:
each of the cartridges ( 12 ) comprises longitudinal interconnection means ( 16 ) arranged in parallel with the center axis ( 15 ), and
adjacent ones of the cartridges ( 12 ) are interconnected to each other in a slidable manner by the interconnection means ( 16 ).

3. The dispenser according to claim 2 , wherein the interconnection means ( 16 ) comprises longitudinal grooves ( 17 ) and tongues ( 18 ).

4. The dispenser according to claim 3 , wherein the interconnection means ( 16 ) extend on a plurality of longitudinal external sides ( 19 ) of each of the cartridges ( 12 ).

5. The dispenser according to claim 1 , wherein the cartridges ( 12 ) are configured to be tilted from a resting position ( 30 ) to an active position ( 31 ).

6. The dispenser according to claim 5 , wherein the resting position ( 30 ) is a position in which the cartridges ( 12 ) are directed rearwards between 0-10 degrees relative a vertical direction ( 26 ).

7. The dispenser according to claim 6 , wherein the active position is a position wherein the cartridges ( 12 ) are directed forwards or rearwards between 10-60 degrees relative the vertical direction ( 26 ).

8. The dispenser according to claim 7 , wherein the cartridges ( 12 ), in the active position, can also be tilted in a sideway direction.

9. The dispenser according to claim 1 , wherein the dispenser ( 2 ) is configured to tilt from a resting position ( 30 ) to an active position ( 31 ) before a countermeasure is fired and to tilt back to the resting position ( 30 ) after a countermeasure is fired.

10. The dispenser according to claim 1 , wherein the tilting means ( 20 ) comprises one fixed hinge-point ( 21 ) attached to the elongate body ( 8 ) and the magazine ( 11 ).

11. The dispenser according to claim 1 , wherein the tilting means ( 20 ) comprises a sliding bar ( 23 ) positioned at a distance from the hinge-point ( 21 ), wherein the sliding bar slidably interconnects the cartridges ( 12 ) via sliding bar connections ( 24 ) attached to the cartridges ( 12 ) which allows for tilting of the magazine ( 11 ) by an actuating means ( 22 ).

12. A method for launching countermeasures ( 5 ) from the dispenser ( 2 ) of claim 1 when mounted on an aircraft ( 1 ), the method comprising the steps of: tilting the cartridges ( 12 ) from a resting position ( 30 ) to an active position ( 31 ) with reference to the direction of motion of the aircraft ( 1 ) and dependent on the relative azimuth and elevation angle to the incoming threat, launching at least one of the countermeasures ( 5 ) toward the incoming threat, and following the launching tilting the cartridges ( 12 ) back into the resting position ( 30 ).

13. The method according to claim 12 , wherein the cartridges ( 12 ), in the resting position ( 30 ), are directed rearwards relative a vertical direction, and wherein the cartridges ( 12 ), in the active position ( 30 ), are directed in a forward direction relative the vertical direction.

14. The method according to claim 13 , wherein the cartridges ( 12 ) are also directed sideways in the active position.
