The AV-8B composite forward fuselage development structure was designed as a flight vehicle. Thus the design incorporates provisions for all functional systems as they relate to the structure. The final design required efforts in structure layout, functional systems integration, trade studies, materials characterization, process development, and configuration iteration. Primary considerations were low cost and light weight. The approach was to design with as few parts and fasteners as possible. This was accomplished by cocuring large graphite/epoxy structural components which required no secondary bonding operations. Component sizes were based on practical geometric shapes, complex tooling limitations, inspection accessibility, and manufacturing assembly sequences. Nomenclature ARBS = angle rate bombing system AWLS = all weather landing system CL = centerline EMI = electromagnetic interference FSD = full-scale development HUD = head-up display IFF = identification, friend or foe IVD = ion vapor deposition OWE = operating weight empty RCS = reaction control system V/STOL = vertical/short takeoff and landing X = buttock line Y = fuselage station Z = water line Background
