A mechanical or electrical technique used in synchro receivers to prevent the rotor from oscillating or spinning?
What is damping.
100
A servo system that contains more than one servo loop,
each loop designed to perform its own function?
What is a multi-loop servo system.
100
A gyro used to detect and measure angular rates of change.
What is a rate gyro.
100
An electromagnetic device that uses one or more saturable
reactors to obtain a large power gain. This device is used in servo systems requiring large amounts of power to move heavy loads.
What is a magnetic amplifier.
200
Systems that transmit data at different transmission
speeds; for example, dual-speed and tri-speed synchro systems.
What is multispeed synchro systems?
200
A component in a servo system that measures position and converts the measurement into a form convenient for transmission as a feedback signal.
What is a position sensor?
200
The tendency of the spin axis of a gyro wheel to remain in a fixed direction in space if no force is applied to it.
What is rigidity.
200
An electromechanical device, used as a position sensor in servo systems, having a terminal connected to each end of a restrictive element, and a third connected to a wiper contact.
What is a potentiometer.
300
The rotating member of a synchro that consists of one or more coils of wire wound on a laminated core.
What is a rotor?
300
A servo system whose end function is to control the position of the load it is driving.
What is a position servo system.
300
The rotation of the spin axis of a gyro in response to an applied force. The direction of precession is always perpendicular to the direction of applied force.
What is precession?
300
Synchros that are designed to meet Navy, rather than
servicewide, specifications.
What is a prestandard Navy synchros.
400
A low voltage used in multispeed synchro systems to prevent false synchronizations.
What is a stickoff voltage.
400
The delay in a servo system between the application of the input signal and the actual movement of the load.
What is time lag.
400
In a gyro, a vector representing the angular velocity of the gyro rotor.
What is a spin vector.
400
An ac or dc amplifier used in servo systems to build up signal strength.
What is a servo amplifier.
500
The process of adjusting a synchro to its electrical zero position.
What is zeroing.
500
A combination of two or more parallel resistors used in servo systems as error detectors. The output of the network is the algebraic sum of the inputs.
What is a summing network?
500
In a gyro, a vector representing the rotary motion applied to change the direction of the rotor axis.
What is torque vector.
500
A small ac or dc generator, sometimes referred to as a rate generator, which converts its shaft speed into an electrical output.
