ABSTRACT:
The invention relates to an actuator system for a projectile having a first and second pair of opposing steering fins disposed in a transverse plane of the projectile. The first pair of opposing steering fins includes a first fin and second fin. The second pair of opposing steering fins includes a third fin and a fourth fin. The actuator system comprises a first motor assembly configured to control the position of the first pair of opposing steering fins, and a second motor assembly configured to control the position of the second pair of opposing steering fins. The first motor assembly and second motor assembly are mounted axially along an axis of the projectile such that a first portion of the first motor assembly is telescopically received within a second portion of the second motor assembly.
