SYSTEM OF ANGULAR STABILISATION OF REVOLVING JET PROJECTILE Russian patent published in 2010 - IPC F42B10/28 F42B15/01 

FIELD: weapons and ammunition.

SUBSTANCE: proposed system comprises angular deviation transducer with sensitive element representing spherical float accommodating permanent annular magnet accommodated in spherical chamber filled with fluid and linked up with drive. Besides system comprises cylindrical magnetic core, signaling and two bearing windings, signal converter with its inputs connected with aforesaid windings and its output connected with gas-dynamic actuator. Said angular deviation transducer incorporates annular short-circuited coil arranged between spherical float and cylindrical magnetic core in plane perpendicular to spherical chamber rotational axis. Height of cylindrical magnetic core is defined by expression H/h=7.5-9.5, where H is core height, h is height of permanent annular magnet, while time constant of angular deviation transducer is selected from expression 0.4≤T≤1.7, where T is time constant [c], while short-circuited coil represents the case of spherical chamber made from nonmagnetic conducting material.

EFFECT: simplified design, higher accuracy.
