8th Symposium on Multidisciplinary Analysis and Optimization.
A new framework consisting of distributed objects for rapid multidisciplinary analysis is developed and applied to a high-speed civil transport configuration. The framework is based on the Common Object Request Broker Architecture (CORBA), a specific
