Engine torque
18. Engine
torque is used to indicate the power that is developed by a
turbo-propeller engine, and the indicator is known as a torquemeter.
The engine torque or turning moment is proportional to the horse-power
and is transmitted through the propeller reduction gear.
19. A torquemeter system is shown in fig. 12-4. In this system, the axial thrust produced by the helical gears is opposed by oil pressure acting on a number of pistons; the pressure required to resist the axial thrust is transmitted to the indicator.
