Aircraft Propeller Torque Measurements

Hi, this may seem stupid but I just have a simple question regarding Torque Measurements.


The basic setup for this Propeller Blade is:

External Sim

Local Rotating Region about Y-axis

Rotation of -500 rad/s (counter-clockwise)

Ambient air conditions (Determining Static Thrust)

SG Torque: applied to all surfaces of all blades

 

I suppose I have two questions:


1. Does the measured torque mean the level of torque required from a motor in order to turn the propeller at given -500 rad/s?


2. Does the negative symbol (SG Torque (Y) -10.655) simply indicated direction of torque (CCW), not an actual negative torque value?

Thank you anyone for your consideration and help,
