Despite enormous advances in polymeric composite materials and related technologies, the use of composites in commercial transport aircraft is currently limited to vertical and horizontal stabilizers and some secondary structures. More widespread use of composites in commercial aircraft structures has been impeded for many and varied reasons. One of these impediments is the lack of established design procedures for use with these materials. That is, current design procedures and philosophies are more-or-less based on the use of homogeneous isotropic metallic alloys. Composites are highly heterogeneous and anisotropic, which greatly complicates the design process and often invalidates existing design procedures and/or philosophies. Due to these complexities, composite structures may be designed very conservatively, seriously eroding the potential weight-saving made possible by modern structural composites. A computer-based optimization design algorithm known as COSTADE is discussed. The primary focus of the paper is on skin-stringer crown panel design, although the approach used is applicable to fuselage keel and side panel design as well. The underlying design philosophy and methods used to calculate effective panel stiffness, strength, damage tolerance, and buckling rigidity are presented. An analysis in which a crown panel design is optimized is included.
