DEVICE FOR ATTITUDE STABILIZATION OF SPIN-STABILIZED MISSILE Russian patent published in 1999 - IPC

FIELD: military equipment, in particular, spin-stabilized missiles, applicable in development of devices for attitude stabilization of guided missiles of salvo missile systems. SUBSTANCE: device uses an angular deviation sensor with a sensing element connected to an electric drive, converter unit and an actuator; in contradistinction to the prototype, according to the invention, the angular deviation sensor is furnished with signal and reference coils; the sensing element of the angular deviation sensor is fitted with a permanent magnet, and the converter unit is furnished with two inverters and series-connected demodulator and low-pass filter, whose output is connected to the actuator input; the demodulator is made in the form of two electronic switches, whose outputs are connected as the demodulator output; the output of the signal coil is connected to the signal input of the first switch directly, and via the first invertor - to the signal input of the second switch; and the output of the reference coil is connected to the control input of the first switch directly, and via the second inverter - to the control input of the second switch. EFFECT: enhanced accuracy of fire due to enhanced accuracy of attitude stabilization. 1 dwg
