ABSTRACT:
The present invention discloses a main rotor collective pitch control assly for rotary wing aircraft. The assembly uses segmented rotor blades. The collective pitch of each movable segment may be independently varied, or may be adjusted in unison with one or more other segments on the same or different rotor blades. Control inputs may be made manually by the pilot or may be made by a computer which interprets data pertaining to the vibrational level and velocity of each rotor span. The pilot may override the computer in the event of system failure or if otherwise desired.
