Given a constant speed propeller, the RPM will stay the same because of the governing system which changes the blade angle. But in cruise flight if you add more power and keep the RPM's the same, there is an increase in airspeed.
So when there is an increase in throttle/MP and more fuel/air mixture goes to the cylinders, does that extra combustive force attempt to spin the shaft faster and thus the blade angle increases and takes a "bigger bite of air"? Or is there some aspect of increased torque force pushing harder against the air?
I prefer the first explanation but I have heard some form of the second one being used, but in a more complete way. I honestly can't remember how that was described and I think I just misunderstood that explanation. What am I missing?
