Target defense system comprising a projectile launcher device
View Patent ↗The invention relates to a defense system for a target against an attacking projectile of the type incorporating a launcher for defensive projectiles and control means for the device after the attacking projectile has been detected, wherein the launcher device comprises a cupola mobile in bearing with respect to the target and a launcher integral with the cupola and articulated in elevation in the bearing range of the cupola to ensure the compactness of the whole assembly with respect to the target.
1. A defense system, comprising:
a cupola having a circular seat for rotating about a central axis, said circular seat having a lateral wall whose height is less than half its external diameter;
a launcher comprising at least two projectile launch tubes, said projectile launch tubes being aligned parallel to each other, said projectile launch tubes each having a length substantially equal to the diameter of said circular seat, said projectile launch tubes being positioned next to each other, an end of said launcher being pivotally attached to said cupola, wherein said launcher is articulated in elevation with respect to said circular seat around trunnions whose ends are fixed along a secant of said circular seat; and
a hydraulic unit located under said launcher and attached to said circular seat, said hydraulic unit for controlling the elevation of the launcher with respect to said circular seat.
2. The defense system according to claim 1 , further comprising a hinge pin integral to said cupola to which said launcher is pivotally attached.
3. The defense system according to claim 2 , wherein said hydraulic unit comprises a jack and a jack rod, said jack attached to said circular seat and said rod attached to said launcher.
4. The defense system according to claim 3 , further comprising a lever having two ends, said lever attached at one end to the rear part of said launcher, the other end of said lever attached to said rod, said lever being pivotally attached to said hinge pin between the two ends of said lever.
5. The defense system according to claim 4 , wherein said launcher may be elevated 10 degrees below horizontal and 70 degrees above horizontal.
6. The defense system according to claim 3 , wherein said jack rod is parallel to a plane of rotation of said cupola when said launcher is at zero elevation.
7. The defense system according to claim 1 , wherein said cupola is rotated with a rack and pinion assembly.
8. The defense system of claim 7 , wherein said pinion is integral with said cupola.
9. The defense system of claim 8 , wherein said rack is attached to a double-acting jack whose piston is activated by a second hydraulic unit.
10. The defense system according to claim 9 , wherein said piston is substantially parallel to said cupola's plane of rotation.
