Abstract

Advanced composite material has attractive potential for reducing the structural mass of modern sailplane components. To achieve this potential, minimum mass design must be provided that simultaneously satisfies a multitude of local and global sailplane design constraints, such as material strength, minimum-gage, buckling, displacement and flutter constraints. An integrated structural design procedure was applied to produce the light weight KORUNDUM sailplane structure. Compared to a conventional design, a mass saving of approximately 6 percent of composite sailplane mass is estimated. The present paper extends an efficient optimality criterion method, and combines system stability constraints with earlier developed material strength, displacement, constraints, etc.
