APPARATUS FOR ANGULAR STABILISATION OF A ROTATING ROCKET Russian patent published in 2021 - IPC F42B10/00 F42B15/01 

FIELD: weapons.

SUBSTANCE: invention relates to military equipment, namely, to control systems of rotating rockets, and can be used, e.g., for angular stabilisation of rockets of multiple launch systems, usually implemented on the active section of the flight path for several seconds after separation of the rocket. The apparatus for angular stabilisation of a rotating rocket comprises a misangulation sensor with a sensing element in the form of a spherical float equipped with a permanent magnet, placed in a spherical chamber made inside the rotor installed in the body on roller bearings, filled with a liquid and mechanically coupled with an electric drive, a signal and reference windings, a signal conversion unit and an executive element, characterised by the fact that the rotor on the side of the end surface is provided with two filling holes located symmetrically relative to the axis of rotation thereof, communicating with the spherical chamber and the hermetically sealed plugs, wherein the value of the radial and axial disbalance of the float is not greater than 2.5∙10^-3 mm, and the surface of balls and races of the ball bearings is equipped with a B 05 grade "Efren-K" fluorine coating.

EFFECT: increase in the accuracy of stabilisation of the angular position of the longitudinal axis of the rocket.
