What is the difference between blended wing body and hybrid wing body?
A blended wing body (bwb), also known as blended body, hybrid wing body (hwb) or a lifting aerofoil fuselage, is a fixed-wing aircraft having no clear dividing line between the wings and the main body of the craft. 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.
Are there any blended wing body prototypes?
The U. S. Air Force has selected innovative aerospace startup JetZero and Northrop Grumman to design, build and fly a full-scale blended wing body aircraft (BWB), which aims to demonstrate enhanced capabilities for improved efficiency, endurance and cargo capacity on multi-mission military and commercial platforms. Unlike traditional aircraft that are limited by cylindrical fuselage constraints, the BWB configuration can accommodate more diverse mission payloads while maintaining efficiency. Future iterations of BWB aircraft could offer additional options across several mission sets for both DoD and commercial markets.
