ASTROS enhancements.

ASTROS (Automated STRuctural Optimization System) is a computer program for the multidisciplinary design and analysis of aerospace structures. ASTROS combines mathematical optimization algorithms with traditional structural analysis disciplines such as static forces, normal modes, static aeroelasticity, and dynamic aeroelasticity (flutter), all in a finite element context, to perform automated preliminary design of an aircraft structure. This report is a complete user's manual that documents the many features of ASTROS through version 12 of the software package. It also provides information on system architecture and other topics of interest. This report is Volume 3 of a set; Volume 1 (WL-TR-93-3025) is the user's manual.In two parts: Part 1, pages i-xxv, 1-434 (chapters 1 -8); Part 2, pages 435-796 (chapters 9 and 10)"This work was performed by Universal Analytics, Inc.
