Nonlinear Buckling & Fatique Analysis of a Large Diameter Sphere & Its Complex Ductwork Under Transient External Pressure (MODEL)

In 2001, Openso Engineering was involved in a project with Northrop Grumman Space Technology (formerly TRW), U.S. Air Force, and Lockheed Martin for development of the YAL-1A Airborne Laser (ABL) system. Openso’s responsibility included performing nonlinear buckling and fatigue analysis of a large diameter sphere and its ductwork under transient external pressure. The sphere and ductwork were part of the recharging equipment for a modified Boeing 747 aircraft equipped with a chemical oxygen iodine laser.
