Abstract
Official abstract text for this publication.
A bond fixture includes a support structure and a first assembly coupled to the support structure. The first assembly includes a frame defining a chamber and a first pressure pad and second pressure pad coupled to the frame opposite one another and positioned within the chamber. The second pressure pad is movable to control a pressure applied by the first pressure pad and the second pressure pad.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of bonding a fairing to a rotor blade comprising: installing a first fairing to a surface of the rotor blade; positioning a first assembly of a bond fixture about the rotor blade adjacent the first fairing; installing a second fairing to another surface of the rotor blade; positioning a second assembly of the bond fixture about the rotor blade adjacent the second fairing; connecting a support structure of the bond fixture to the rotor blade to restrict movement of the bond fixture relative to the rotor blade, the support structure comprising a brace including a contour complementary to the first assembly and the second assembly; adjusting a position of one or more pressure pads of the first assembly; applying localized and constant pressure to the first fairing via the bond fixture; and adjusting one or more fasteners to contact at least one of the one or more pressure pads of the first assembly or at least one of the one or more pressure pads of the second assembly with the rotor blade. 2. The method of claim 1 , further comprising: adjusting a position of one or more pressure pads of the second assembly; and applying localized and constant pressure to the second fairing via the bond fixture. 3. The method of claim 1 , wherein localized and constant pressure is applied to the first fairing and the second fairing simultaneously. 4. The method of claim 1 , further comprising aligning openings of the support structure with openings of a blade cuff. 5. The method of claim 4 , further comprising inserting pins through the aligned openings to couple the support structure to the rotor blade. 6. A method of bonding a fairing to a rotor blade comprising: installing a first fairing to a surface of the rotor blade; positioning a first assembly of a bond fixture about the rotor blade adjacent the first fairing; installing a second fairing to another surface of the rotor blade; positioning a second assembly of the bond fixture about the rotor blade adjacent the second fairing; connecting a support structure of the bond fixture to the rotor blade to restrict movement of the bond fixture relative to the rotor blade, the support structure comprising a brace including a contour complementary to the first assembly and the second assembly; adjusting a position of one or more pressure pads of the first assembly; applying localized and constant pressure to the first fairing via the bond fixture; and aligning openings of the support structure with openings of a blade cuff. 7. The method of claim 6 , further comprising inserting pins through the aligned openings to couple the support structure to the rotor blade. 8. The method of claim 6 , further comprising: adjusting a position of one or more pressure pads of the second assembly; and applying localized and constant pressure to the second fairing via the bond fixture. 9. The method of claim 8 , further comprising contacting at least one of the one or more pressure pads of the first assembly and the one or more pressure pads of the second assembly with the rotor blade. 10. The method of claim 6 , wherein localized and constant pressure is applied to the first fairing and the second fairing simultaneously.
