This paper summarizes the aeroelastic activities performed by AIRBUS Defence & Space (AIRBUS-DS) for the preliminary design of the A330-AWACS (Airborne Warning and Control System), which is based on the AIRBUS A330-200 platform that is modified to include a dome-type radar on top of the fuselage. The A330-AWACS general design concept is detailed with emphasis on those features that impact on the Aeroelasticity or the Dynamic Loads of the basic aircraft. Flutter of the dome-struts structure is analyzed in three configurations: isolated clamped-to-floor, isolated clamped-to-fuselage, and dome-struts installed in the A330-200 (complete aircraft simulations). Ground and flight dynamic loads scenarios used for the preliminary design are also detailed. Improvements on both static and dynamic aeroelastic calculations by using CFD computations are briefly described. Finally, further developments and tasks are enumerated.
