US12710256 - Projectile and fuze with fin

The patent describes a projectile equipped with a target finder and extensible fins that induce a controlled oscillating movement, enhancing the target scanning area. This design allows for improved targeting accuracy by adjusting the oscillation characteristics based on fin shape, extension, and movement parameters.

Claim 1

1 . A projectile adapted to be launched from a launching device, the projectile comprising a target finder, and one or more extensible fins, wherein the one or more fins, upon launching of the projectile and extension of the fins, cause the projectile to be put into a controlled oscillating movement to provide a conical scan area of increased size compared to a non-oscillating target scan area for the target finder around the original trajectory, said oscillating movement characteristic of one or more of a selected fin shape of the one or more fins, an amount of fin extension of the one or more fins, a frequency or interval of fin extension of the one or more fins, a speed of fin extension of the one or more fins, and an acceleration of fin extension of the one or more fins, and wherein the target finder controls the projectile flight after locating an identified target and delimits the oscillations to focus on the identified target.
