GYRO-STABILISED PAYLOAD STABILISATION SYSTEM OF AN UNMANNED AERIAL VEHICLE Russian patent published in 2021 - IPC G01C21/18 B64C39/00 

FIELD: aircrafts.

SUBSTANCE: invention relates to the field of aircraft systems, in particular, to unmanned aerial vehicles for operational transport infrastructure maintenance monitoring, protection of objects, monitoring of territories, needs of law enforcement authorities, search for people. The gyro-stabilised payload stabilisation system of an unmanned aerial vehicle consists of a three-stage gyroscope, angular momentum sensors, pitch and roll frames, a tracking stabilisation system, and vibration damping elements. The stabilisation system is therein made in the form of a mounting platform, bolted whereon is the lower support of the damper, wherein vibration damping elements are located between the lower and upper supports of the damper, made in the form of twelve round rubber dampers, the damper supports are made of carbon fibre, the pitch frame constitutes a pitch truss made in the form of a platform, bolted whereon is a stool with an electric roll motor installed inside. The roll angle sensor and the roll angle sensor cover are located on the upper part of the stool with the electric roll motor, the panning truss is made in the form of a base with a bolted connection with the electric panning motor, a pitch angle sensor is installed on the panning truss base, wherein a stool with an electric pitch motor installed inside is installed opposite said sensor, the cover whereof is installed in the upper part of the stool with the electric pitch motor. The pitch angle sensor cover is installed on the base by means of a bolted connection, the electric roll motor is bolted to the roll console, attached whereon are a video camera, a video camera control board, and a three-stage gyroscope installed under the video camera. The panning angle sensor cover is therein located on the upper support of the damper and is common for the controller installed on the upper support of the damper and configured to be connected to the autopilot of the unmanned aerial vehicle.

EFFECT: provided possibility of controlling the position of the video camera in order to stabilise the video image and track the target.
