THREE-MEMBER ANGULAR VELOCITY METER Russian patent published in 2003 - IPC

FIELD: measurement technology. SUBSTANCE: proposed three- member angular velocity meter includes first, second and third gyroscope transmitters of angular velocity with relatively perpendicular measuring axes, first, second and third two-input summers with first inputs of first second and third summers being connected with outputs of first, second and third angular velocity transmitters, respectively. First and second delay devices, first and second signal cycle meters first, second and third three-input multipliers are introduced additionally. Output of first angular velocity transmitter is connected with input of first delay device whose output is connected is connected with second input of third multiplier. output of third angular velocity transmitter is connected with input of second delay device whose output is connected with second inputs of first and second multipliers. Output of first angular velocity transmitters connected also with input of first signal cycle meter whose output is connected with third input of third multiplier. output of third angular velocity transmitter is connected with input of signal cycle meter whose output is connected with third inputs of first and second multipliers. first input of first multiplier is connected with output of first angular velocity transmitter, and input of second angular velocity transmitter is connected with first inputs of second and third multipliers. Output of second multiplier is connected with second input of first summer, output of first multiplier is connected with second output of second summer and output of third multiplier is connected with second input of third summer. So, use of invention makes it possible to measure angular velocities which have no components caused by effect of noncommutativity of final turnings. EFFECT: reduced errors in measurement of angular velocity. 1 dwg
