Boeing 797

Boeing 797
Boeing is preparing a new 1000-passenger airplane. The new Boeing 797 with it's Blended-Wing-Body (BWB) design, was designed in Cooperation with NASA. The new airplane is a response to Airbus's A380 which can carry up to 555 passengers (in three-class configuration), and up to 853 passengers in a full economy configuration.

The 797, with a 265ft wingspan, has a 3ft longer wingspan than the A380, which has a wingspan of 262ft. The 797's BWB design has several big advantages, such as the lift-to-drag ratio, which will have a 50% increase over the A380, combined with the 25% less overall weight than the A380, the 797 is expected to have about 33% efficiency over the Airbus's A380. The BWB shape also decreases the stress on the air frame, and reduces turbulence, therefor increasing the body rigidity and efficiency. Link>>>>>
