In recent years unconventional aircraft configurations, such as Blended - Wing - Body (BWB) aircraft and B2 wing, are being investigated and researched with the aim to develop more efficient aircraf t configurations, in particular for very large transport aircraft that are more efficient and environmentally - friendly. These configurations designate an alternative aircraft configuration where the wing and fuselage are integrated which results essentiall y in a hybrid flying wing shape. The purpose of this research is to assess the aerodynamic efficiency of a blended wing body aircraft with respect to a B2 wing configuration, and to identify design issues that determine the effectiveness of the “Blended Wi ng and B2 wing” performances. The approach was undertaken to develop a new conceptual design of a BWB aircraft using Computational Aided Design (CAD) tools and Computational Fluid Dynamics (CFD) software. The research contains several geometry parameters w hich are varied to investigate the influence on the aerodynamic and stability characteristics of two configurations. In the last part, a special case has been explored in an attempt to improve the stability by changing geometry parameters.
