I forgot to mention the amount of flex in the rotor blade and amount of flapping is all dependent upon forward airspeed and the load being transmitted to the disc. How much does the aircraft have to lift , fuel load , cargo load and external freight, it will all have an effect. So for each...
A somewhat brief answer to your question. The advancing rotor blade increases in forward velocity. Known as the leading blade. The retreating blade decreases its forward velocity. The lagging blade. So the advancing blade speeds up and the retreating blade slows down. As the advancing blade...
