“…This chapter lays out basic methods for modeling a paneled morphing skin that covers a morphing mechanism, called variable geometry wingbox (VGWB). The theory, analysis, motion control, and optimization of the VGWB was presented in [41]. The basic design of the VGWB is depicted in Figure 3-1, and this mechanism is capable of morphing all six DOFSs, covering the four morphing modes, namely, dihedral, sweep, twist, and span.…”
