Reverse Velocity Rotor System for Rotorcraft

T. D. Verrill / J. R. Ewans

A blade control method and means for helicopter rotors which increases helicopter speed by mixing two/rev. control motion with one/rev. cyclic and collective motion through mechanical summation is provided. Both rotary and vertical motions are imparted to an inner control shaft and these motions are combined to impart vertical oscillatory motions to the rotor head which motions increase the thrust developed by the helicopter rotor.
