SIGHT LINE STABILIZER Russian patent published in 2005 - IPC

FIELD: gyro equipment, in particular, biaxled gyro stabilizers of optical sight lines, operating on movable objects and designed for stabilization and control of the sight line.

SUBSTANCE: the device has a frame, mirror, actuating motors of the azimuth and attitude channels, installed on the hinge lines of the frame and mirror, amplifier monitoring unit of the azimuth and altitude channels, the output of which of them is coupled to the input of the actuating motor of the respective channel, attitude sensor installed on the mirror hinge line, gyroscopic sensor of the azimuth channel pitch rate of the azimuth and the gyroscopic sensor of the pitch rate of the attitude channel. The gyroscopic sensor of the pitch rate of the attitude channel is installed on the reverse side of the mirror so that its sensitivity axis is in parallel with the axis of rotation of the mirror, and the gyroscopic sensor of the azimuth channel angular rate is installed on the frame so that its axis of sensitivity is in parallel with the axis of rotation of the frame. A differentiating device is used in addition, computer determining the tangent of the doubled input value, multiplier, adder, subtracter and an additional gyroscopic pitch-rate sensor installed on the frame so that its axis of sensitivity is perpendicular to the axes of rotation of the frame and mirror.

EFFECT: reduced mass and overall dimensions of the stabilization system, enhanced accuracy of the biaxial controllable gyro stabilizer due to absence of kinematic transmission between the mirror and gyroscopic sensors.
