Just curious. Anyone here studied the translational lift generated by a gyroplane rotor system. Like percent of total lift attributed to the forward motion of the gyroplane.

100% of the lift generated by a gyro rotor in level flight is due to the deflection of the 'relative wind' downwards. Here's a drawing due to Jean Claude:

What about during a vertical descent in which a gyroplane has no forward speed?
That's an special case. The rotor is powered by the relative wind blowing from below the disk, and the rotor does indeed produce a certain amount of lift, that has the same value and opposite direction as the weight of the gyro. Hence, the machine falls at a constant velocity...
