Abstract: A method for guiding an artillery projectile to a target. In one embodiment, the method includes providing control commands to change an angle of attack of one or more roll stabilizing fins and providing control commands to change an angle of attack of one or more lift guiding fins; and controlling the roll angle to provide a lift force to guide the projectile along a trajectory, wherein the projectile is configured to spin about its longitudinal axis during flight.

Abstract: A device for improving the aerodynamic feature of a projectile is disclosed. The projectile has a front part and a rear part. The external diameter of the front part of the projectile is larger than the external diameter of the front end of a rear part of the projectile. The front end of the rear part of the projectile is conical having larger diameter at locations behind the front end. The device comprises an annular cut-off cone sleeve slidably disposable over the front part of the projectile. The diameter of the narrower end of the annular cone sleeve is slightly larger than the diameter of the front part of the projectile and the length of the annular cut-off cone sleeve is larger than the distance between the front end of the rear part of the projectile and a location on rear part having a diameter equal to the diameter of the rear end of the annular cut-off cone sleeve.

Abstract: A device for sealing a projectile guiding kit may be used with any kit having a rear unit and a front unit rotatably connectable to the rear unit thereof. The device may include an annular body adapted to envelope at least a front portion of the rear unit and at least a rear portion of the front unit of the kit. The device may include a flexible ring-shaped strip attached to an inner side and at a front end of the annular body and adapted to seal a gap between the rear unit and the front unit of the kit. The annular body may be adapted to slide towards the rear unit of the kit when subjected to a longitudinal acceleration that exceeds a predetermined acceleration value, thereby uncovering the gap and enabling uninterrupted rotation of the front unit with respect to the rear unit of the kit.

Abstract: An apparatus and method for guiding a cannon shell accurately are disclosed. The apparatus includes two main parts adapted to be installed on the leading end of the cannon shell. The front main part of the apparatus is equipped with at least one pair of fins and is rotatable with respect to the rear main part. The pair of fins is controlled to hold the front main part substantially stable with respect to an external reference frame when the cannon shell rotates as it flies towards its target. Control system is comprised within the apparatus that receives location signals and is adapted to provide guiding control commands to the cannon shell via the fins so as to guide the shell accurately to its preprogrammed target. The control system is adapted to activate the detonation chain of the shell according to preprogrammed mode.
