All trends indicate that composite aerostructures are continually getting more complex. This isdue in large part to the fact that aircraft assemblies have huge volumes of highly interdependentdesign information. Creating the initial designs and making subsequent changes to these complexaerostructures is both time-consuming and error-prone. In this session you will learn how atightly integrated suite of software and services for aerostructure development greatly increasesthe design and manufacturing efficiency as well as the quality of today’s complex compositeaircraft assemblies.In the aftermath of the first intensive, large commercial composite airframe programs,exemplified by the Boeing 787 Dreamliner, many aircraft manufacturers are selecting carbonfiber reinforced plastic (CFRP) as the structural material of choice for the fuselage and/or wingof their next project. This is true for all types and sizes of commercial airplanes, including large,regional, business and general aviation aircraft.In this transitional period into a new age for the aerospace industry, lessons on compositeengineering and manufacturing must be assimilated quickly to transform or adapt the overalldevelopment process to this new reality. The complexity of the multiple interactions betweenmaterial choices, tooling selection, design methodology and manufacturing process must beunderstood and mastered in order to devise the most robust and efficient approach.In this presentation we describe how VISTAGY has been able to draw on more than 15 years ofleadership in composite design and its close association with the major actors of the globalaerospace industry supply chain to propose a global and flexible approach to composite airframedevelopment with fiber placement and tape laying.The main ingredients of composite airframe development are reviewed in the context of a CADintegrated specialized environment including elements such as the overall fiber orientationstrategy over complex shapes, the design methodology, concurrent design and stressoptimization and validation, design for the manufacturing process, composite assemblyengineering and manufacturing and quality control procedures.
