A static rotor blade assembly balancing apparatus, the apparatus comprising:
- a vertical rod having a top end;
- a tip located at the top end on a vertical axis of the rod;
- and
- a sleeve having a bore terminating at a socket, in use the rod is disposed in the bore and the tip and the socket form a pivot connection, wherein the sleeve is balanced to settle in a level position with a vertical axis of the sleeve coaxial with the vertical axis of the rod and wherein the sleeve has an outer profile configured to mount a hub of a rotor blade assembly.
A method for balancing a rotor blade assembly, the method comprising:
- connecting a sleeve in a hub of a rotor blade assembly, the sleeve having a bore terminating at a socket;
- mounting the sleeve and the rotor blade assembly on a vertical rod having a tip, wherein the vertical rod is disposed in the bore and the tip and the socket are in pivoting contact at a pivot point;
- measuring a balance of the rotor blade assembly;
- and
- balancing the rotor blade assembly if it is not balanced.
