摘要

This paper describes the conceptual development of a novel flying boom for air-to-air refuelling of passenger aircraft. This operational approach is currently evaluated within the EC project RECREATE as a possible means to achieve significant increase in overall fuel efficiency. While in military aviation aerial refuelling is performed with the tanker flying ahead and above the receiver aircraft, in case of passenger aircraft, an inverted set up is suggested to increase safety, cost and comfort criteria. This unconventional refuelling configuration would require a different refuelling boom, able to extend from the tanker towards the cruiser, against wind and gravity. A MDO computational framework is set up in order to investigate a number of boom design options, accounting for the various involved disciplines (structure, control, aerodynamics and static aeroelastics). The obtained feasible solutions are subsequently analysed in accordance with the current certification specifications for dynamic stability. A feasible design space is found where the proposed concept appears to be fully controllable and free of static and dynamic aeroelastic instability.
