What are the advantages of blended wing body?
Advantages of the blended wing-body concept include high fuel efficiency, low noise and a large payload volume for the size of the aircraft. Blended-Wing-Body Aircraft Design The blended-wing-body (BWB) aircraft eliminates the division between main aircraft body and wings, enabling the entire aircraft to generate lift and reduce aerodynamic drag. Improved aerodynamics directly improves fuel efficiency and payload.The blended wing body aircraft will allow the U. S. Air Force to learn and apply capabilities for increased efficiency, endurance and capacity for future missions. Blended wing body aircraft have the potential to significantly reduce fuel demand and increase global reach.A blended wing aircraft body enables 20% more volumetric space and 30% better fuel efficiency for freight cargo when compared to traditional aircraft design.Blended-Wing-Body (BWB) layout is a new type of aircraft configuration that has an appearance between the flying wing and the conventional ‘tube and wing’ aircraft. The highly blended wing and fuselage can provide some amount of lift; hence, BWB aircraft have a larger lift-to-drag ratio than conventional aircraft.
What is the most common application of blended wing bodies?
The BWB design delivers multiple compounding benefits that address the aviation industry’s most pressing challenges. The list of challenges for a BWB in scheduled service is long. The cabins will have to make do with fewer windows—a significant change for passengers. Passengers sitting nearer the plane’s extremities in particular will have to be prepared for noticeable vertical acceleration when the aircraft starts to turn.
What is the future of blended wing body aircraft?
Blended wing body aircraft represent a radical shift in commercial aviation design, with the potential to drastically improve fuel efficiency, reduce carbon emissions, and enhance passenger experience. By reducing drag, Blended Winglets increase fuel efficiency and boost range. Blended Winglets enhance longitudinal and directional stability, thereby providing better handling in turbulence.
Are blended wing body aircraft more stable?
Since BWB aircraft eliminate the horizontal tail and use a small-area V tail instead of a vertical tail, the longitudinal and directional static stability of the aircraft is significantly reduced. The pitch and yaw damping of BWB aircraft is small, and the aerodynamic and stability characteristics are strongly coupled. 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.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.
