What are the advantages of a blended wing?
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. Meet the Z4, a blended-wing-body (BWB) aircraft with a highly aerodynamic and lightweight airframe that JetZero says will deliver up to a 50% reduction in fuel burn and greenhouse gas emissions compared with traditional tube-and-wing airplanes that are currently in service, even while using the same conventional .The blended-wing–body (BWB) is an example of an advanced aircraft design with low-noise features. The design differs from the traditional tube-and-wing configuration; the vehicle has overwing-mounted engines that introduce shielding of engine noise, as well as simplified high-lift devices that reduce airframe noise.
How does blended wing body save fuel?
By better integrating the fuselage and wing, the aircraft achieves more lift and therefore can utilize smaller engines which will reduce fuel consumption by 30% while simultaneously providing 30-40% more usable interior space. A low-wing aircraft generally has less drag when compared to a high-wing aircraft, making it more efficient in cruise performance; this means faster speeds and lowers fuel consumption.
