The Blended Wing body configuration is a hybrid shape capable of combining a flying wing with a conventional airplane. In order to assess the feasibility and the possible pros and cons, Flight Test Vehicles (FTVs) design’s are necessary . This represents a low cost and risk based approach compared to the full scale configuration. Six 7% scaled Unmanned Aerial Vehicles (UAVs) for flight tests have already been built and tested at the Center for Aerospace research (CfAR) in order to obtain information on the control and aerodynamics of the aircraft. The in-flight tests conducted showed encouraging results and prompted Bombardier Aerospace investigate further, committing an even larger scale.
