PROCEDURE FORMING INSTRUCTION FOR ROLL CONTROL OVER REGULARLY SPINNING ROCKET MISSILE WITH USE OF AERODYNAMIC FORCES AND GEAR FOR ITS IMPLEMENTATION Russian patent published in 1999 - IPC

FIELD: development of missile guidance systems. SUBSTANCE: procedure can be used in complexes of antitank and antiaircraft guided missile systems. In agreement with invention formed program-time signal is additionally modulated with signal of first or second degree of relation of roll rotational speed of missile at moment of start of control to roll running rotational speed of missile. Prior to modulation with signal of roll rotational speed of missile there is formed signal in correspondence with dependence , where U(t) is program-time signal; is roll rotational speed of missile at moment t₀ of start of control; is roll running rotational speed of missile; n=1, 2. Gear for formation of instruction for control over missile has source of program-time signal and roll meter and modulator connected in series. Gear is supplemented with meter of period of roll signal which input is connected to output of roll meter, storage which input is linked to output of meter of period of roll signal, time unit which output is connected to controlling input of storage, divider which divisible input is connected to output of meter of period and input of divider is linked to output of storage, functional exponentiation converter which input is connected to output of divider and second modulator whose first input is connected to output of source of program-time signal, whose second input is linked to output of functional exponentiation converter and whose output is coupled to second input of first modulator. EFFECT: increased accuracy of guidance of missile due to diminished error emerging from action of gravitational force on missile. 2 cl, 1 dwg
