Abstract:

Blended wing body (BWB), as per the name is a single body comprising both the wings and the body of the aircraft, unlike conventional aircraft where wings are attached to the fuselage and can be distinguished in the aircraft’s structure. The advantages of BWB include drag reduction, high lift to drag ratio of overall body, higher fuel efficiency, increased seating capacity and reduced hangar space at the airport. At present the concept of BWB is not likely to be manufactured due to the limiting constraints of structures, aero-structural integration, issues pertaining to pressurization of the cabin, as well as the large frontal area of the wing that would in turn increase the drag coefficient. To overcome the aeromechanical issues the flow simulation over the BWB is done. The 2-D geometry was developed and kept as close as possible to the real designs gathered from the literature review. The results of the flow simulation fulfil the conditions set forward in the theory. The contours of various parameters depict the accurate variation in the flow regime around the BWB body.
