Abstract:
1. A projectile with incidence steerable control surfaces comprising at least two control surfaces, each control surface being rotatable with respect to the projectile around a pivot axis perpendicular to a longitudinal axis of the projectile, wherein the projectile comprises: central means for controlling the control surfaces comprising at least a sphere, a center of the sphere being on the longitudinal axis, the sphere being arranged in a housing of the projectile, a control arm secured to the sphere and adapted to rotate the sphere at least around the pitch and yaw axes of the projectile passing through the center of the sphere, for each control surface, a transmission member cooperating with the sphere by a first side and with a foot of the control surface by a second side, wherein the transmission member is intended to transmit to the control surface rotation movements of the sphere around the pivot axis of the control surface, means for positioning the control arm adapted to position an end of the control arm in a position determined with respect to an absolute frame centered on the longitudinal axis of the projectile.
