Torque transmitter
Torque transmitter is attached on the torque limiter, it measures torque
produced by the power turbine by comparing oil pressures (reduction gear
and power turbine) and converts pressure difference into a voltage which is
applied to torquemeter.
Propeller overspeed limiter
Propeller overspeed limiter is installed on left side of the reduction gear box. It
prevents a propeller overspeed in case of main propeller governor failure.
Propeller overspeed limiter is equipped with a test solenoïd which allows
performing ground tests by arming limiter under normal overspeed power.
”PROP O’SPEED TEST” propeller test push–button (Figure 7.6.3) of
overspeed limiter is located on instrument panel near propeller speed
indicator.
Torque limiter
Torque limiter is located on right side of the reduction gear box. It is rated to
limit engine torque to 110 %.
