Abstract
An apparatus for controlling a trajectory of a projectile includes a planetary drive train, a yaw drive assembly engaged with the planetary drive train, and a pitch drive assembly engaged with the planetary drive train. The apparatus further includes a plurality of fin assemblies linked with the planetary drive train such that, as the planetary drive train is actuated by at least one of the yaw drive assembly and the pitch drive assembly, corresponding displacements are produced in the plurality of fin assemblies.
Claims71
An apparatus for controlling a trajectory of a projectile, comprising:
- a planetary drive train;
- a yaw drive assembly engaged with the planetary drive train;
- a pitch drive assembly engaged with the planetary drive train;

An apparatus for controlling a trajectory of a projectile, comprising means for epicyclically actuating a plurality of fins using outputs from at least one of a roll actuator, a yaw actuator, and a pitch actuator.
An apparatus for controlling a trajectory of a projectile, comprising:
- means for linking a plurality of fins to a yaw actuator and a pitch actuator via a planetary gear train;
- and
- means for driving the yaw actuator and the pitch actuator to displace the plurality of fins.
A projectile, comprising:
- a flight control system disposed within the fuselage, wherein the flight control system comprises:
- a planetary drive train;
- a yaw drive assembly engaged with the planetary drive train;
- a pitch drive assembly engaged with the planetary drive train;
- and
- a plurality of fin assemblies extending through the fuselage and linked with the planetary drive train such that, as the planetary drive train is actuated by at least one of the yaw drive assembly and the pitch drive assembly, corresponding displacements are produced in the plurality of fin assemblies.
An apparatus for controlling a trajectory of a projectile, comprising:
- means for steering the projectile;
- means for producing a mechanical output corresponding to a yaw and a pitch of the trajectory;
- and
- means for epicyclically linking the means for producing the mechanical output and the means for steering the projectile.
