A spin-stabilized projectile is steered by taking air from an air intake at the front of the projectile, and expelling the air along an outer surface of the projectile to alter its trajectory toward the desired impact location. Air taken in through the air intake is directed toward a rotor that is able to rotate relative to the rest of the projectile. The rotor has an outlet that may direct the air taken in at the air inlet out in a direction having both radial and circumferential components. The force produced in the radial direction provides a steering force substantially normal to the projectile axis, used to steer the projectile. The force produced in the circumferential direction is used to provide impetus to spin the rotor. A brake is used to control the rotational speed of the rotor, to control the direction that the air is expelled from the projectile.

What is claimed is: 1. A module for a spin-stabilized projectile comprising:a module body;a rotor mechanically coupled to the module body, wherein the rotor has an inlet passage and an outlet passage in fluid communication with each other, with the outlet passage expelling air in a different direction from that in which air is received at the inlet passage; anda control system for controlling rotation and positioning of the rotor.
