초록

A spin-stabilized projectile has a collar around the middle of its spun fuselage, longitudinally spanning a center of mass of the projectile. The collar includes lift-producing aerodynamic surfaces. Positioning the collar relative to the spinning fuselage produces a direct lift force on the projectile that may be used to steer the projectile. Since the projectile is constantly spinning, the positioning may be accomplished by a brake, such as a magnetic brake or a fiction brake, that allows the collar to be positioned substantially fixed relative to inert...

청구항

1. A projectile comprising: a spin-stabilized fuselage; anda collar having lift-producing aerodynamic surfaces;wherein the collar is positionable relative to the spin-stabilized fuselage by relative rotation about a longitudinal axis of the projectile; andwherein the collar longitudinally spans a center of mass of the projectile. 2. The projectile of claim 1, wherein the aerodynamic surfaces have a fixed angle of attack. 3. The projectile of claim 1, wherein the aerodynamic surfaces have a variable angle of attack. 4. The projectile of claim 1, further c...
