Munition and guidance navigation and control unit

Abstract

A guidance and control unit assembly for use with a munitions projectile includes a guidance and control unit being roll isolated with respect to the munitions projectile such that roll of the munitions projectile about a projectile longitudinal axis, such roll being imparted to the munitions projectile during the act of launching the munitions projectile, may not be imparted to the guidance and control unit as desired. A munitions projectile is further included.

1 . A guidance and control unit assembly for use with a munitions projectile, the guidance and control unit being roll isolated with respect to the munitions projectile such that roll of the munitions projectile about a projectile longitudinal axis, such roll being imparted to the munitions projectile during the act of launching the munitions projectile, may not be imparted to the guidance and control unit as desired. 
     
     
         2 . The guidance and control unit assembly of  claim 1  including imparting control to the munitions projectile by no more than a pair of opposed, deployable canards. 
     
     
         3 . The guidance and control unit assembly of  claim 1 , including a pair of opposed canards being deployable for effecting roll stabilization of a guidance and control unit member. 
     
     
         4 . The guidance and control unit assembly of  claim 1 , including a first spindle and a second spaced apart spindle. 
     
     
         5 . The guidance and control unit assembly of  claim 1  having a first spindle and a second spaced apart spindle and bearing means interposed between the first and second spindles. 
     
     
         6 . The guidance and control unit assembly of  claim 5 , the bearing means including at least two bearing units. 
     
     
         7 . The guidance and control unit assembly of  claim 6  wherein the two bearing units are disposed substantially adjacent one another. 
     
     
         8 . The guidance and control unit assembly of  claim 6  wherein the two bearing units each include an outer ring and a spaced apart inner ring. 
     
     
         9 . The guidance and control unit assembly of  claim 6  wherein a plurality of roller bearings are captured between a respective outer ring and a corresponding inner ring. 
     
     
         10 . The guidance and control unit assembly of  claim 1  having a total weight of less than 22.0 lbs. 
     
     
         11 . The guidance and control unit assembly of  claim 1  having a total weight of less than 13.2 lbs. 
     
     
         12 . The guidance and control unit assembly of  claim 1  having a total volume that is less than 100.0 cubic inches. 
     
     
         13 . The guidance and control unit assembly of  claim 1  having a total volume that is less than 87.0 cubic inches. 
     
     
         14 . A munitions projectile assembly having a selectively couplable guidance and control unit assembly, a guidance and control unit of the guidance and control unit assembly being roll isolated with respect to a munitions projectile subassembly when coupled to the munitions projectile subassembly such that roll of the munitions projectile subassembly about a projectile longitudinal axis, such roll being imparted to the munitions projectile during the act of launching the munitions projectile, may not be imparted to the guidance and control unit as desired.
