CONTROL DEVICE FOR THE ATTITUDE AND HEADING REFERENCE SYSTEM Russian patent published in 2023 - IPC G01C19/02 G01C23/00 

FIELD: aircraft.

SUBSTANCE: control device for the attitude and heading reference system consists of a gyrovertical with systems of longitudinal and transverse corrections and an inductive angle sensor mounted on the suspension axis of the inner frame, while the outer frame, on the suspension axis of which the pitch-axis reference is fixed, is cinematically installed in the tilt frame, with the suspension axis of which is cinematically the roll-axis reference and the first testing engine are connected, the input of which is electrically connected to the output of the first amplifier, the directional gyroscope with a horizontal correction system, on the suspension axis of the outer frame of which the heading angle reference is fixed, cinematically installed in the pitch-axis frame, on the suspension axis of which, located perpendicular to the suspension axis roll frame, a pitch angle receiver is installed, electrically connected to the pitch angle sensor, and a second exhaust motor connected to the output of the second amplifier, the input of which is connected to the output of the pitch angle receiver, as well as a roll frame controller made in a certain way.

EFFECT: increased accuracy of operation at unlimited pitch angles.
