METHOD FOR FORMATION OF CONTROL SIGNALS OF ROLL-STABILIZED AMMUNITION, ROLL-STABILIZED AMMUNITION Russian patent published in 2003 - IPC

FIELD: guided ammunitions that are fired from gun barrel and designed for hitting of ground armored targets. SUBSTANCE: in the method for formation of control signals of roll-stabilized ammunition arbitrally installed in roll at loading in the gun barrel the information of the gyro roll sensor at a sine-cosine conversion and summation of the yawing and pitching control signals is formed in the form of a reflected binary code with a reference mark of a turn in the axis of symmetry of the roll sensor curtain, compensation of the lag of response of the control actuator consisting of two components is effected by the angular advance of the function of the reflected binary code relative to the control surfaces, the first component of the advance is inserted beforehand at alignment of the control surfaces relative to the curtain, and the second component of advance is generated in the ammunition angular velocity electronic equipment. The controlled roll-stabilized ammunition, containing a control actuator, electronic control equipment, gyro with a roll sensor with a caging device, spherical pendulum, body and a warhead, additionally uses an on-board electronic function generator, type OR-gate, whose input is coupled to a gyro roll angle transmitter, and the output - to the input of the control equipment, the gyro with the roll angle transmitter is of a spring type with a matched type gyromotor and an optronic roll sensor, in which the curtain of the "yes-no" type is freely installed on the axle of the outer gyroscope frame and connected to the load of the physical pendulum, and the two optopairs of the gyroscope are shifted relative to each other through 90 deg and positioned in the body, the axis of symmetry of the curtain and the reference point of the function of signal transduction in the electronic function generator are shifted relative to the vertical axis of the pendulum and coinciding with the instantaneous position of the control surface respectively through the advance angles of the response of the control surfaces in the direction against the rotation of the body, the alignment of the optopairs relative to the control surface is made through the setting angle equal to the angular position of the optopairs relative to the vector of the kinematic moment. EFFECT: enhanced accuracy and reliability of ammunition operation due to the complete compensation of the phase errors in the control system both predicted beforehand and appearing in the process of the guided flight. 2 cl, 4 dwg
