Question about the Basics of Torque
I'm trying to wrap my head around what torque is in a turbine helicopter.
I get that in a helicopter like the B206, the N1 turbine drives the turbine compressors, and that it's output flow drives N2 turbine without a mechanical connection.
From here I get fuzzy. I am thinking that the N2 turbine drives the rotor via the transmission and mechanical connections.
So, given the above, I get what N1, N2, and Nr are measuring, but not Torque.
Thanks for the help,
Patrick
