Patent ID: 8317477

Claim:
A pitch-adjustment assembly for selectively adjusting a first rotor blade's pitch, said first rotor blade being contained within a first rotor blade assembly, while selectively simultaneously adjusting a second rotor blade's pitch, said second rotor blade being contained within a second rotor blade assembly, said first rotor blade assembly having operatively connected thereto a first rotor assembly connector, said second rotor blade assembly having operatively connected thereto a second rotor assembly connector, said first rotor assembly connector and said second rotor assembly connector being supported by a frame, said pitch-adjustment assembly comprising: a first mounting bracket supported by said first rotor assembly connector; a first post connected to said first mounting bracket; a first pitch communicator extending at least partially through said first post, said first pitch communicator being operatively connected to said first rotor blade; a first coupler supported by said first post and operatively connected to said first pitch communicator; a first handle supported by said first coupler, said first handle being configured to be manipulated by an operator and further configured such that manipulation of said first handle translates to manipulation of said first pitch communicator and adjustment of said first rotor blade's pitch in a first particular pitch amount; a second mounting bracket supported by said second rotor assembly connector; a second post connected to said second mounting bracket; a second pitch communicator extending at least partially through said second post, said second pitch communicator being operatively connected to said second rotor blade; a second coupler supported by said second post and operatively connected to said second pitch communicator; a second handle supported by said second coupler, said second handle being configured to be manipulated by an operator and further configured such that manipulation of said second handle translates to manipulation of said second pitch communicator and adjustment of said second rotor blade's pitch in a second particular pitch amount; a flexible shafting cord having a first cord end and a second cord end, said first cord end being operatively connected to said first coupler, said second cord end being operatively connected to said second coupler; said pitch-adjustment assembly being further configured such that manipulation of said first handle selectively translates via said flexible shafting cord to manipulation of said second handle and adjustment of said second rotor blade's pitch such that said second particular pitch amount is essentially equal to said first particular pitch amount; wherein operation of said first handle selectively leads to equal pitch adjustment of both second first rotor blade and said second rotor blade.
