Abstract
A disc-shaped member-to-be-aimed is mounted for tilting about two mutually perpendicular tilt axes rotatable about a third and mutually perpendicular boresight axis that affords a conical field of view for the member in the presence of any asymmetry in its tilting about the tilt axis. A multi-gimbal assembly accommodates such multiple-axis movement freedom, and torque motors disposed in an axialwise direction at one side of the member-to-be-aimed affords radial compactness for the gimbal assembly.
Claims8
A directional assembly comprising:
- a generally cylindrical roll gimbal rotatable about a boresight axis at its center;
- a member-to-be-aimed mounted on said roll gimbal for tilting about a tilt axis perpendicular to said boresight axis;
- a torque motor mounted on said member-to-be-aimed at one side thereof;
- said torque motor having a rotary output shaft extending radially inward toward said boresight axis;
- a reaction rod extending generally along said boresight axis;
- device means connecting one end of said reaction rod to said output shaft;
- and,
- means at the center of said roll gimbal in axialwise and radialwise sliding cooperation with the opposite end region of said reaction rod.
