    摘要： When two structural components are to be joined, for example, when an aircraft skin section is to be secured to a stringer by an adhesive bonding, it is important that the joining surface areas are plane to avoid the formation of air inclusions in the joint because air inclusions weaken the mechanical strength of the joint. Thus, a surface topography that is not plane must be smoothed out prior to the joining. For this purpose the surface areas to be joined are optically scanned to provide topographical information for each surface area that needs to be smoothed out for providing a plane joining surface. The topographical information is processed to ascertain the configuration and volume of the surface topography that needs to be filled with a filler material to produce a plane surface or at least a smooth surface without hills and dales. A respective control signal is produced and fed to a dosing equipment which supplies the exact volume of filler material required for planing or smoothing the surface topography. When smoothing is completed the two components are ready for joining for example by the application of pressure and heat to the filler material.

    摘要： A global optimization tool may be used to predict characteristics of a multiple ply layered composite as a condition of one or more continuous variables and/or one or more binary variables. For example, the global optimization tool may predict characteristics of a composite for a large range of fiber orientation angles of each of layer of the ply. The optimization tool may include solving a mixed integer nonlinear programming (MINLP) model to obtain a multiple ply layered composite design that is optimized relative to objectives, such as areal weight and cost. Thus, the global optimization tool may be able to identify composite designs with lower areal weight and/or lower cost than the composite designs identified by prior art trial and error methods or heuristic algorithms. When a composite design is identified as meeting certain criteria that are input to the global optimization tool, that composite design may be manufactured.
