초록
The present invention relates to a method and a device for correcting the trajectory (7, 8, 10, 11) of a spin-stabilised projectile (12) in azimuth by controlling its rate of spin by devices (18-21) deployable on the outside of the projectile (12) where they act on the airflow.

The expandable stent of claim 2, wherein the substantially "U" shaped elements are connected to one another to define a substantially sinusoidal pattern extending circumferentially along each cylindrical segment, the sinusoidal pattern having an amplitude alternatively defined by the first and second longitudinal lengths. 4. The expandable stent of claim 1, wherein the tubular member comprises a circumference, and wherein the connector further comprises a pair of connectors located opposite one another on the circumference for facilitating articulation of the adjacent cylindrical segments about the longitudinal axis. 5. The expandable stent of claim 1, wherein the connector includes a curved portion extending at least partially circumferentially along a circumference defined by the plurality of cylindrical segments. 6. The expandable stent of claim 5, wherein the curve of the connector defines a sinusoidal shape adapted to extend and compress axially substantially evenly when the adjacent cylindrical segments are subjected to a predetermined bending force about the longitudinal axis. 7. A stent, comprising: a plurality of tubular segments defining a circumference and a longitudinal axis, each tubular segment including an alternating pattern of curvilinear elements extending about the circumference, the alternating pattern including a first set of curvilinear elements having a first resistance to expansion and a second set of curvilinear elements having a second resistance to expansion substantially higher than the first resistance to expansion; and a connector extending between tubular segments that are adjacent to one another. 8. The stent of claim 7, wherein each tubular segment is expandable between a contracted condition, a first expanded condition, and a second expanded condition, the first expanded condition being achieved when a radial force exceeding the first resistance to expansion is applied to the tubular segment, the second expanded condition being achieved when a radial force exceeding the second resistance to expansion is applied to the tubular segment. 9. The stent of claim 8, wherein each tubular segment is plastically deformable between the contracted condition, the first expanded condition, and the second expanded condition. 10. The stent of claim 7, wherein each tubular segment comprises a continuous alternating amplitude zigzag pattern, the first set of curvilinear elements defining a first amplitude and the second set of curvilinear elements defining a second amplitude, the first amplitude being longer than the second amplitude. 11. The stent of claim 10, wherein first and second sets of curvilinear elements comprise "U" shaped elements. 12. The stent of claim 10, wherein the first and second sets of curvilinear elements alternate about the circumference to define the zigzag pattern. 13. The stent of claim 7, wherein each tubular segment comprises a continuous alternating amplitude zigzag pattern, the first set of curvilinear elements comprises a first thickness and the second set of curvilinear elements comprise a second thickness, the first thickness being smaller than the second thickness. 14. A stent, comprising a plurality of tubular segments defining a circumference and a longitudinal axis, each tubular segment including an alternating pattern of curvilinear elements extending about the circumference, the alternating pattern including a first set of curvilinear elements having a first resistance to expansion and a second set of curvilinear elements having a second resistance to expansion substantially higher than the first resistance to expansion, each tubular segment being expandable between a contracted condition, a first expanded condition, and a second expanded condition, the first expanded condition being achieved when a radial force exceeding the first resistance to expansion is applied to the tubular segment, the second expanded condition being achieved when a r
