CFD ANALYSIS OF BLENDED WING BODY AND B2 WING
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 2
Abstract
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 aircraft 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 essentially 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 Wing 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 which 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.
