Helicycle belt tension is carefully set so the belts will slip in an overtorque so as not to exceed transmission limitations.
The Helicycle turbine is also set up to prevent overspeed by shutting the fuel to idle via a different control than a throttle chop.
And the only way to find that out was to have an actual overtorque and overspeed. It would not show up in ground checks.
But if "over torque" only causes the belts to slip, then one could overspeed it on the ground checks to confirm fuel shut off to idle is set correctly, right?
