Abstract
A device for driving in rotation fins of a projectile, the fins being of the deployable type integral with fin heads which are able to be oriented along an axis of spin (X, Y) substantially orthogonal to a projectile's longitudinal axis (Z), wherein the fin heads are driven in rotation by motors and substantially ring sector-shaped sliders which slide in a circular groove.
Claims9
A device for driving deployable fins of a projectile having a longitudinal (Z) axis, the device comprising:
- a body with a central axis (Z′) and being connectable to a projectile, with its central axis (Z′) generally coinciding with a longitudinal axis (Z) of such a projectile;
- rotatable fins extending radially outwardly from the body along spin axes (X′, Y′) generally orthogonal to the central axis (Z′);
- motors mounted within the body with the axis of rotation of each motor generally parallel to central axis (Z′);
- a fin head connecting each fin to only a corresponding one of said motors through a corresponding slider of ring sector shape;
- the body having a circular groove therein centered on and orthogonal to central axis (Z′) said groove in a plane that is orthogonal to the longitudinal (Z) axis of the projectile;
- and
- the ring sector-shaped sliders are located in the circular groove, and each motor is connected to one of the sliders for driving said one slider in the circular groove thereby rotating the fin connected to said corresponding slider.
