The invention relates to a rotationally stabilized projectile (1) for launching from a barrel, which projectile (1) comprises a front projectile part (22), a rear projectile part (20) comprising a rotating band (4), and an intermediate projectile part (21) comprising a freely rotatable middle section (2) arranged with guide wings (3) for improving the gliding capability and guidance capability during the gliding phase and end phase of the projectile. The guide wings (3) are arranged extensibly on the freely rotatable middle section (2), and the intermediate projectile part (21) also comprises a regulator device (14) for regulating the rotation of the middle section (2). The invention also relates to a method for guiding a rotationally stabilized projectile.
Rotationally stabilized projectile for launching from a barrel, having improved gliding capability and guidance capability during the gliding phase and end phase of the projectile, which projectile comprises a front projectile part, a rear projectile part comprising a rotating band, and an intermediate projectile part comprising a freely rotatable middle section arranged with guide wings, wherein the guide wings are arranged extensibly on the freely rotatable middle section, and in that the intermediate projectile part also comprises a regulator device for regulating the rotation of the middle section.
Method for guiding a projectile during the gliding and end phase of the projectile, which projectile comprises a front projectile part, a rear projectile part comprising a rotating band, and an intermediate projectile part comprising a middle section rotatable relative to the projectile and arranged with guide wings, wherein the projectile is guided towards its target by extension of the guide wings and by virtue of the fact that the rotation of the rotatable middle section via a regulator device, in response to control signals from a control unit, is regulated to the correct position relative to the projectile.
