M esd Multidisciplinary Aspects of Design E5D 71 Emphasis is on the multidisciplinary nature of the complex engineering systems design process. Aero space vehicles are a particular class of such systems Structures Control Emphasis in recent years has been on advances that can Aerodynamics be achieved due to the inter- action of two or more disciplines o Massachusetts Institute of Technology -Prof de Weck and Prof. Willcox
