Stabilized Gimbal for Moving and Airborne Platforms
A gimbal for airborne and moving platforms that uses a gyroscope as a rotational anchor for payload stabilization. Unlike current stabilized gimbals that sense rotations and correct by using motors, the proposed gimbal uses a passive approach that maintains the payload orientation instead of forcing it back after it rotated out of the desired orientation.
1 . A gimbal for airborne platforms comprised of a fast-spinning mass (gyroscope) and two, primary and secondary frames having orthogonal exes of rotation nested within one another. Said gyroscope is connected to said frames in a way that provides orientational stability to said secondary frame by using the gyroscopic forces developed in said gyroscope.
2 . A gimbal for airborne platforms comprised of a fast-spinning mass (gyroscope), a primary frame rotatable around a primary axis, a secondary frame rotatable around a secondary axis perpendicular to said primary axis and nested within said primary frame, and a linkage. Said gyroscope spins at a fast rotational speed to provide gyroscopic force thus orientational anchoring to said primary frame around said primary axis. Said gyroscope is connected to said primary frame along said secondary rotational axis. Said secondary frame is connected to said primary frame with a pivot axis parallel to said secondary rotational axis. Said linkage connects said gyroscope to said secondary frame in a way that transfers the motion of said gyroscope to said secondary frame around said secondary rotational axis. Said Gimbal with all said components provides orientational stability to said secondary frame regardless of said platform's orientation.

7 . A gimbal for moving platforms comprised of a fast-spinning mass (gyroscope), a primary frame rotatable around a primary axis, a secondary frame rotatable around a secondary axis perpendicular to said primary axis and nested within said primary frame, and a linkage. Said gyroscope spins at a fast rotational speed to provide gyroscopic force thus orientational anchoring to said primary frame around said primary axis. Said gyroscope is connected to said primary frame along said secondary rotational axis. Said secondary frame is connected to said primary frame with a pivot axis parallel to said secondary rotational axis. Said linkage connects said gyroscope to said secondary frame in a way that transfers the motion of said gyroscope to said secondary frame around said secondary rotational axis. Said Gimbal with all said components provides orientational stability to said secondary frame regardless of said platform's orientation. Said gimbal with all said components operational provides orientational stability to said secondary frame regardless of said platform's orientation.
