blended wing body, or bwb, designates an alternative airframe design which incorporates design features from both a traditional tube and wing design into a hybrid flying wing configuration. the claimed advantages (see potential advantages below) of the bwb approach are efficient high-lift wings and a wide airfoil-shaped body. this enables the entire craft to contribute to lift generation with the result of potentially increased fuel economy.
currently, both nasa and a maior airlines constructor are exploring bwb designs under the designation x-48. studies suggest that bwb aircraft, configured for passenger flight, could carry from 450 to 800 passengers and achieve fuel savings of over 20 percent. nasa has been developing, since 2000, a remotely controlled model with a 21 ft (6.4 m) wingspan. this research is focused on establishing the base data concerning the lift, stall and spin characteristics inherent in a blended wing body design. 打印准备: 否
