Abstract
A projectile has the ability to generate and provide power to components located in two sections of the projectile which have relative rotation to each other. The projectile has a pair of generators allowing the powering of components in two sections. The projectile has a force-producing device for altering the direction of the projectile as the projectile moves along the longitudinal axis of the projectile and the relative rotational position of the force-producing device on the projectile is controlled by a generator.
Claims23
A projectile comprising:
- a shell having a charge;
- a guidance and control assembly, having a front section and a rear section, the sections rotatably mounted to each other;
- the rear section of the guidance and control assembly secured to the shell;
- the front section of the guidance and control assembly having an aerodynamic device for influencing the relative rotation of the front section of the guidance and control assembly relative to the rear section and the shell;
- a first generator having an armature and a field, the field carried by one of the sections of the guidance and control assembly and the armature carried by the other section;
- a second generator having an armature and a field, the field carried by the section carrying the armature of the first generator and the armature carried by the section carrying the field of the first generator;
- and
- one of the generators scavenging power from relative rotation of the front and rear sections to power at least one electrical component located in the front section of the guidance and control assembly, the other generator scavenging power to power at least one electrical component located in the rear section of the guidance and control assembly and in the shell.

A projectile comprising:
- a shell having a charge;
- a guidance and control assembly, having a front section and a rear section, the sections rotatably mounted to each other;
- the rear section of the guidance and control assembly secured to the shell and having a detonator;
- the front section of the guidance and control assembly having an aerodynamic device for influencing the relative rotation of the front section of the guidance and control assembly relative to the rear section and the shell;
- a generator having an armature and a field, the field carried by one of the sections of the guidance and control assembly and the armature carried by the other section, the generator scavenging power from the relative rotation to power at least one component;
- and
- a force-producing device for exerting a force substantially perpendicular to the longitudinal axis of the projectile to alter the path of the projectile.
4 more elements
A method of targeting a projectile, the method comprising the steps of:
- firing the projectile from a gun;
- creating a rotation of the projectile along a longitudinal axis of the projectile due to the rifling of the barrel of the gun;
- rotating a front section of the guidance and control assembly of the projectile relative to a rear section of the guidance and control assembly and a shell of the projectile by a plurality of aerodynamic devices carried by the front section interacting with the air as the projectile moves through the air;
- creating power in the projectile by having a pair of generators in the guidance and control assembly wherein each generator has a field and armature and the field of one of the generators and the armature of the other generator is carried by the front section and the armature of the one of the generators and the field of the other generator is carried by the rear section;
- and
- powering at least one component in each of the sections of the guidance and control assembly with power from the respective generator.
