System and method for controlling high spin rate projectiles
First Claim
1. A method for controlling a flight trajectory of a spinning projectile, comprising:
- supporting a nose of said projectile in a manner permitting said nose to be wobbled relative to a base portion of the projectile;
coupling at least one electrically responsive component at a first end to said nose and at a second end to said base portion of said projectile;
sensing an angular position of said nose of said projectile as said projectile flies through an atmosphere after being fired from a weapon; and
controllably applying an electrical signal to said electrically responsive component, in relation to said sensed angular position of said nose, to control an attitude of said nose during flight of said projectile.

Abstract
A method is disclosed for controlling a flight trajectory of a spinning projectile. In one aspect the method may involve supporting a nose of the projectile in a manner permitting the nose to be wobbled. At least one electrically responsive component may be coupled at a first end to the nose and at a second end to a base portion of the projectile. An angular position of the nose of the projectile may be sensed as the projectile flies through an atmosphere after being fired from a weapon. An electrical signal is controllably applied to the electrically responsive component, in relation to the sensed angular position of the nose, to control an attitude of the nose during flight of the projectile.

9. A method for controlling a flight trajectory of a spinning projectile, comprising:
-
supporting a nose of said projectile in a manner permitting said nose to be wobbled; supporting said nose by a plurality of circumferentially spaced apart, electrically responsive components; detecting when said projectile has been fired from a weapon; sensing an angular position of said nose and a rate of spin of said projectile as said projectile flies through an atmosphere after being fired from said weapon; and controllably applying electrical signals having different phases to said plurality of electrically responsive components, in relation to said sensed angular position of said nose, to control an attitude of said nose during flight of said projectile. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A system for controlling a flight trajectory of a spinning projectile, comprising:
-
a projectile having a nose and a body portion, with the nose portion being supported for movement relative to the body portion; a plurality of electrically responsive components coupled between said nose and said body portion; and a subsystem that senses an angular position of said nose after said projectile has been fired from a weapon and generates electrical signals that are applied to said electrically responsive components to counteract said wobbling motion to maintain said nose in a relatively constant, desired attitude during flight of said projectile. - View Dependent Claims (18, 19, 20)
