Abstract
In one embodiment, a rotor blade balancing apparatus may include a tube member defining an inner cavity, a plurality of weights, and a biasing member. The tube member may be for the insertion into a cavity of a rotor blade. Each of the weights may be adapted to be slide-ably inserted into the inner cavity of the tube member within a cavity of a rotor blade, and slide-ably removed from the inner cavity of the tube member within a cavity of a rotor blade in order to balance a rotor blade. The biasing member may be for biasing weights, which have been slide-ably inserted into the inner cavity of the tube member within a cavity of a rotor blade, towards an end of the tube member.
