An apparatus for securing first and second skins to a core in a composite rotor blade includes an elongated member configured to be installed through a passage in the core of the composite rotor blade. The elongated member has a first end configured to be attached to an outer surface of the first skin and a second end configured to be attached to an outer surface of the second skin. The apparatus also includes a first patch configured to adhere the first end to the outer surface of the first skin, and a second patch configured to adhere the second end to the outer surface of the second skin such the elongated member extends from the outer surfaces of the first and second skins through the passage in the core.

Securing assembly for a rotor blade

A method of assembling a rotor blade includes determining first spanwise and chordwise moments of a first component of the blade and comparing the first spanwise and chordwise moments to respective target first spanwise and chordwise moments. The first spanwise and/or chordwise moment(s) of the first component is/are adjusted based upon corresponding results of the comparison to provide balancing of the first component. Second spanwise and chordwise moments of a second component of the blade are determined and compared to respective target second spanwise and chordwise moments. The second spanwise and/or chordwise moment(s) of the second component is/are adjusted based upon corresponding results of the comparison to provide balancing of the second component. The balanced first and second components are assembled to each other so that target spanwise and chordwise moments of the blade are met.
