Aerodynamic Analysis of Blended Wing Body Business Jet

Abstract

Aerodynamic analysis of the BWB business jet is performed to analyze the flow field around the aircraft at high subsonic flight speed. Because of the cabin height, center body section is designed relatively thicker than general transonic airfoils. REA 5212 airfoil is selected for wing section. ANSYS Fluent is used for aerodynamic analysis of the BWB business jet. Because of the center body section produces less lift than wing section, strength of local shock on the center body is weaker than wing section. The weaker shock on the center body has advantage of locating the engine intake.
