Tandem motor actuator
First Claim
1. 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 including a first fin and second fin, the second pair of opposing steering fins including a third fin and a fourth fin, the actuator system comprising:
- 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,wherein 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.

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.

15. In a projectile having a plurality of steering fins disposed in a first transverse plane of the projectile, the plurality of steering fins including a first fin opposing a second fin, and a third fin opposing a fourth fin, an actuator system for controlling the positioning of the plurality of steering fins comprising:
-
a first forward motor assembly adapted to apply torque to a first output shaft coupled to the first fin and a second output shaft coupled to the second fin such that the first output shaft and the second output shaft rotate in a first rotational direction; a second rearward motor assembly adapted to apply torque to a third output shaft coupled to the third fin and a fourth output shaft coupled to the fourth fin such that the third output shaft and the fourth output shaft rotate in a second rotational direction, wherein 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. - View Dependent Claims (16, 17, 18, 19, 20)
