I think that the gearbox efficiency in the horizontalAxisWindTurbinesADM.C (Line 869) is defined incorrectly. Writing out the equation from this line (in continuous time) leads to:
J_r\dot{\omega}_r = \eta_gT_r\rho - GT_g
by doing the derivation myself, I would think that the gearbox efficiency should be at the generator side, like this:

Do you agree? Or am I missing something?
