    摘要： A method (100) for repairing a composite member (200) includes assembling (110) a composite stack (205) on a surface (300). The composite stack includes a first book (215) nested with a second book (225). An adhesive (210) is disposed between the first book and the second book. At least one of the first book and the second book includes a first pattern of slots. The method further includes setting (120) the composite stack to yield a composite repair piece (240). The method further includes attaching (130) the composite repair piece to the composite member. Also disclosed is a composite repair piece. The composite repair piece includes a first book and a second book. The second book is stacked on top of the first book. An adhesive is disposed between the first book and the second book. At least one of the first book and the second book includes a first pattern of slots.

    摘要： Systems and methods are provided for fabrication of frames for aircraft. One such method for fabricating a frame (150) for an aircraft (10) comprises receiving a frame (150), advancing the frame (150) through one station of an array (160) of stations arranged in an arc and/or through a series of stations in a helical arrangement corresponding to a shape of the frame (150) and performing work on the frame (150) via at least one of the stations.
    One such system for fabricating a frame (150) of an aircraft (10) comprises an array (160) of stations that are arranged in an arc, and that perform work upon the frame (150) at the same time and/or the system comprises a helical stack (1750) comprising a curved track (1720) that proceeds vertically at a pitch angle in a helical shape; and stations (1722) disposed along the curved track (1720) that perform work on the frame (150) as the frame (150) advances along the curved track (1720) and a drive unit (102) that advances the frame (150) through the stations.

    摘要： A laser alignment system (42) for adjusting a mounting bracket (70, 72) of a lamp (68, 74) is disclosed. The laser alignment system (42) includes an alignment bracket (44) including a body portion (142) defining one or more target features (54A, 54B, 54C) and a plurality of index features (42A, 42B, 42C). The one or more target features (54A, 54B, 54C) include a target (180) that is configured to align with a laser beam (62) and the plurality of index features (42A, 42B, 42C) that are configured to position the alignment bracket (44) along a surface. The laser alignment system (42) also includes a laser alignment tool (46) including a base (56), a mount (58), and a laser device (60). The mount (58) holds the laser device (60) in place, and the laser device (60) is configured to emit the laser beam (62). The base (56) of the laser alignment tool (46) is shaped to fit within the mounting bracket (70, 72) for the lamp (68, 74) and the laser device (60) directs the laser beam (62) towards a corresponding one of target features (54A, 54B, 54C) of the alignment bracket (44).
