Thrust is a function of velocity, the fan is basically a positive displacement pump so if rpm increases in a bench test the load/thrust increases. Only burried in poor designed ducting will this not happen. Even if the inlet ring is left off the rpms and thrust will rise and fall together.
The CS70 is loaded up with so much pitch the motor becomes critical, if it cant make enough torque it wont have good performance at higher voltages.
