Abstract

The proposed two-gyroscopic SE is designed to measure acceleration and belongs to the area of acceleration measurements on a moving base and can be used in stabilization systems. The purpose of the article is to increase the accuracy of acceleration determination. To do this, it is necessary to eliminate methodical errors of gyroscopic moments-obstacle from the cross angular velocities of the base and from the angular velocity of the Earth's rotation. The proposed two-gyro SE consists of a three-stage gyroscope located in the inner and outer frames, equipped with an inter-frame correction system, which includes an angle sensor located on the axis of the inner frame of the gyroscope, the output of which is connected to a moment sensor located on the axis of the outer frame.

What is new in the two-gyro SE stabilizer is the application on the axis of the inner frame of the gyroscope with the possibility of rotating the rotor in the opposite direction of the main gyroscope, equipped with an inter frame correction system, which includes an electric angle sensor located on the axis of the inner frame of the gyroscope, to the output of which the control winding of the electric moment sensor is connected. Located on the axis of the outer frame, and both gyroscopes are equipped with two additional angle sensors located on the axes of the outer frames, the outputs of which are connected to two additional moment sensors located on one axis of the inner frame, the centers of gravity of the two three-stage gyroscopes are equally shifted to one side along the axes of rotation gyroscope rotors relative to the axes of the outer frames.
