METHOD AND DEVICE FOR IMPROVING STABILIZATION AND MANOEUVRING ABILITY OF UNMANNED FLYING VEHICLES (UFV) USING A GYROSCOPIC EFFECT

摘要

The proposed invention (a method and a device) is related to control systems and is intended for improving UFV stability and manoeuvring ability; it can be used for control and correction of various dynamic objects including small-size satellites. The objective of the invention is decreasing UFV sensitivity to influence of wind and turbulence without increasing flying speed, and improvement of stability and manoeuvring ability at the same time. For improving the above-listed parameters, UFV, together with compensation of the gyroscopic moment and propeller moment reaction, must increase the kinetic moment by means of a gyroscope. This is attained by that the gyroscope is installed, relative to the UFV centre of gravity, opposite the propeller (in case of a rear position of the propeller, the gyroscope is installed in the front part), rotation of the gyroscope rotor is directed contrary to the propeller rotation (rotation axles of the gyroscope rotor and the propeller are in alignment); the device having a high kinetic moment becomes less sensitive to influence of wind and turbulence, stability of flying increases; to change the flight path, the rotation axle of the gyroscope rotor is turned by means of electric motors (stabilization and moments motors) and reduction gears mounted on rotation axles of rotatable frames so that direction of generated gyroscopic moments coincide with the UFV turning direction. Coincidence of directions of gyroscopic moments with moments of the elevation rudder and directional rudder improves UFV manoeuvring ability. Stabilization and changing the angular position of UFV heel about the longitudinal axis are performed by increasing or decreasing the rotational speed of the gyroscope rotor with an adjustable inertia moment.
