ABSTRACT:
According to embodiments described in the specification, provided is a rotor drum for use with a multiple-rotor wind turbine, the rotor drum being mountable on a generator shaft of a generator. The rotor drum comprises a plurality of rotors, each rotor being configured to permit a mounting of a plurality of blades. The rotor drum further comprises a plurality of cross straps affixed to the plurality of rotors for maintaining each of the plurality of rotors in a predetermined spaced-apart relationship. The rotor drum is provided with a mounting coupler provided on at least one of the plurality of rotors for affixing the rotor drum on the generator shaft.
