COMPUTATIONAL AERODYNAMIC ANALYSIS OF BLENDED WING BODY MAV DESIGN

Md. Akhtar khan, Arjun Jagini

Abstract: The Blended Wing Body (BWB) configuration has the potential to change the way subsonic transport airplanes are designed. In the past ten years, fuel efficiency and noise reduction have become the two biggest challenges for aircraft manufacturers. This paper deals with the computational aerodynamic analysis of a BWB airplane at subsonic speeds using Ansys CFD as a simulation tool and ICEM CFD as a modeling tool. The study will focus on the aerodynamic characteristics such as the pressure, velocity variation over the body at different angle of attack. We are also calculating the aerodynamic efficiency (lift force to drag force ratio) so that we can compare the performance of a BWB aircraft with a conventional aircraft.
