he ASTROS (Automated Strucutral Optimization System) procedure provides multidisciplinary analysis and design capability for aerospace structures. The engineering analysis capabilities in the system include structural analysis (static and dynamic), aeroelastic analysis (static and dynamic) and automated design. A specifically designed data base and executive system were implemented to maximize the system's efficiency, flexibility, and maintainabilit The charts used in the ASTROS User Training Workshop, conducted by the Air Force and Northro are presented in this report. .

FOREWORD Contract F33615-83-C-3232, entitled "Automated Strength-Aeroelastic Design of Aerospace Structures," was initiated by the Analysis and Optimization Branch (FDSR) of the Air Force Wright Aeronautical Laboratories. The objective of this contract was to develop a computer procedure which can assist significantly in the preliminary automated design of aerospace structures. This report consists of materials used at the ASTROS User Workshop. Northrop Corporation, Aircraft Division, was the primary contractor for this program with Universal Analytics. Inc. (UAI) and Kaman AviDyne acting as subcontractors. The principal contributors to this report were: E. H. Johnson, the overall Program Manager at North:op D. J. Neill, Project Co-Principal investigator, D. L. Herendeen, the Project Manager at UAI, and R. A. Canfield, the Air Force Project Engineer. Capt R. A. Canfield was the Air Force Project Manager while Dr V. B. Venkayya initiated the program at the Air Force and provided overall program direction. Th_ work reported on in this report was performed from 01 July 1983 through 24 June 1988. The authors would like to acknowledge those who acted as instructors at the ASTROS User Training Workshop held at Wright-Patterson AFB from 20 June to 24 June, 1988: Capt Robert Canfield Mr Mark French Mr David Ferguson Mr David Herendeen Dr Erwin Johnson
