METHOD FOR MINIMIZING THE AVERAGE FLIGHT ALTITUDE OF AN AIRCRAFT MOVING NEAR AN UNEVEN SURFACE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2022 - IPC G08G5/00 B64C13/02 G05D1/08 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation and can be used in aircraft control systems (AC). The desired value of the track angle and the maximum allowable deviation from it is set, its current value and the rate of change are measured. The difference in the true geometric heights of the left side of the wing and the right, rate of change thereof is determined. The control signal is generated and transmitted to a direction rudder which is non-linearly dependent on the difference of these values, the rate of change thereof, the difference between the predetermined and current values of the track angle and the rate of change thereof, the maximum allowable deviation from the track angle. The device comprises radar altimeters, a vertical velocity Doppler sensor, three vertical acceleration inertial sensors, the outputs of which are connected to a module for calculating the average sea level, true geometric and absolute heights, a steering unit directly acting on the elevator height.

EFFECT: invention makes it possible to minimize and increase accuracy of stabilization of average height of AC movement.
