What are the benefits of blended wing body aircraft?
The main advantage of the BWB is to reduce wetted area and the accompanying form drag associated with a conventional wing-body junction. It may also be given a wide airfoil-shaped body, allowing the entire aircraft to generate lift and thus reducing the size and drag of the wings. The BWB configuration is said that the wings, integrated to the larger and wider aerofoil centre body allows the entire aircraft to generate lift and reduce parasite drag, in particular interference drag (Leibeck, 2004; Qin et al.Compared to the Flying Wing design, the BWB features a more defined center body, which contributes to its structural integrity and aerodynamic efficiency.The combined effects of reduced drag and improved lift characteristics result in significant fuel efficiency improvements. BWB aircraft consume 30% less fuel compared to conventional designs which is essential for meeting modern aviation’s environmental and economic challenges.
