Longitudinal static stability of a blended wing-body unmanned aircraft with canard as longitudinal control surface / Rizal E. M. Nasir, Wahyu Kunjoro and Wirachman Wisnoe

Blended wing-body (BWB) aircraft, while having good aerodynamic efficiency, is hampered with issues related to its flight stability and control. To ensure longitudinal stability, a control canard is incorporated on Baseline-II E-2 BWB design. Mathematical representations of aerodynamic characteri...
