Ground-Projectile Guidance System

摘要

A guidance unit system is configured to be used for a ground-launched projectile. The system includes a housing configured to be attached to a ground-launched projectile. The housing is coupled to an attachment region that attaches to the projectile, wherein the housing is configure to rotate relative to the attachment region. A motor is contained within the housing and a bearing surrounding the motor. The bearing is rigidly attached to the housing such that the motor rotates with the housing and shields the motor from inertial loads experienced by the housing.

1. A guidance unit system for a ground-launched projectile, comprising:
a housing configured to be attached to a ground-launched projectile, the housing having a bullet-nosed region and an attachment region, wherein the attachment region inserts into the projectile, wherein the bullet-nosed region of the housing rotates relative to the attachment region of the housing; at least two canards attached to the housing; a motor contained within the housing; a bearing surrounding the motor such that the motor is contained entirely within the bearing, the bearing being rigidly attached to the housing such that the motor rotates with the housing and shields the motor from inertial loads experienced by the housing, wherein the bearing rotates about an axis perpendicular to a long axis of the ground launched projectile.
