Next, as an effort of the authors during recent years, the development and BFF investigation of scaled vehicles is introduced. The design, build and test campaigns are detailed, first for a blended wing body (BWB) vehicle, and then for a conventional configuration. Theoretical and experimental correlation study is conducted for the aeroelastic stability of both vehicles. Finally, it is concluded with the pros and cons of the present work. |
