DEVICE FOR FORMATION OF RELAY CONTROL SIGNALS OF SPIN-STABILIZED MISSILE Russian patent published in 2002 - IPC

FIELD: development of missile guidance systems, applicable in guides anti-tank and guided anti-aircraft missile complexes. SUBSTANCE: the device has drivers of control signals in the vertical and horizontal planes, whose outputs are connected respectively to the first inputs of the first and second modulators, summing amplifier, whose first and second inputs are connected respectively to the outputs of the first and second modulators. The device has also a gyroscopic missile roll-angle pick-off, whose first output is connected to the second input of the first modulator, and the second output is connected to the second input of the second modulator; the signals from the first and second outputs of the gyroscopic roll-angle pick-off are relay three-position ones, shifted relative to each other through angle π/2. The device uses a driver of the linearization signal, whose input is connected to the second output of the gyroscopic roll-angle pick-off, logical device, whose input is connected to the second output of the gyroscopic rollangle pick-off, third modulator, whose first input is connected to the output of the driver of the linearization signal, the second input is connected to the output of the logical device, and the output is connected to the third input of the summing amplifier, as well as a two-position relay element (comparator), whose input is connected to the output of the summing amplifier. EFFECT: enhanced accuracy of guidance of spin-stabilized missiles with relay control actuators. 4 dwg
