Previous set of "T" Terms
TORQUE. A measure of how much load a machine can turn. This measurement is expressed either in
ounce-inches for torque synchro systems or in pound-feet for heavy machinery.
TORQUE DIFFERENTIAL RECEIVER (TDR). A type of differential synchro that takes two electrical
inputs, one to the rotor and one to the stator, and produces a mechanical output. The output is the
angular position of the rotor that represents the algebraic sum or difference of the two electrical inputs.
TORQUE DIFFERENTIAL SYNCHRO SYSTEM. A synchro system containing either a TDX or a
TDR. This system is used in applications where it is necessary to compare two signals, add or subtract
the signals, and furnish an output proportional to the sum or difference between the two signals.
TORQUE DIFFERENTIAL TRANSMITTER (TDX). This type of synchro is functionally the same as
the CDX, except that it is used in torque systems rather than control systems.
TORQUE GRADIENT. A term used in the rating of torque synchros. It is expressed in the number of
inch-ounces of torque required to pull a specific synchro 1 degree away from its normal position; for
example, 0.4 inch-ounce per degree.
TORQUE RECEIVER (TR). A type of synchro that converts the electrical input supplied to its stator
back to a mechanical angular output through the movement of its rotor.
TORQUE SYNCHRO SYSTEM. A synchro system that uses torque synchros to move light loads such as
dials, pointers, and other similar devices.
TORQUE TRANSMITTER (TX). This type of synchro is functionally the same as the CX, except that it
is used in torque synchro systems.
TORQUE VECTOR. In a gyro, a vector representing the rotary motion applied to change the direction of
the rotor axis. The torque vector represents the axis about which the applied force is felt.
TOTAL RESISTANCE. (RT) The equivalent resistance of an entire circuit. For a series circuit: RT = R1 +
R2 + R3 ...Rn. For parallel circuits:
TOXIC VAPORS.Vapors emitted by a substance that can do bodily harm.
TR RECOVERY TIME. Time required for a fired tr or atr tube to deionize to a normal level of
conductance.
TRACK. Operational phase of a fire-control or track radar during which the radar beam is kept on the
target.
TRACK RADAR. Radar that provides continuous range, bearing, and elevation data by keeping the RF
beam on the target. [Radar Terms]
TRANSCONDUCTANCE. Transconductance is a ratio of the change in plate current to a change in grid
voltage with the plate voltage held constant. Transconductance (gm) is usually expressed in micromhos
or millimhos.
TRANSFORMER EFFICIENCY. The ratio of output power to input power, generally expressed as a percentage.
TRANSFORMER, STEP-DOWN. A transformer so constructed that the number of turns in the secondary winding is less than the number of turns in the primary winding. This construction will provide less voltage in the secondary circuit than in the primary circuit.
TRANSFORMER, STEP-UP. A transformer so constructed that the number of turns in the secondary winding is more than the number of turns in the primary winding. This construction will provide more voltage in the secondary circuit than in the primary circuit.
