November 1, 2006 Ground testing of the X-48B Blended Wing Body (BWB) concept will start in the near future in preparation for flight testing early next year. The X-48B ground and flight testing will take place at NASA's Dryden Flight Research Center at Edwards Air Force Base in California, where two high-fidelity 21-foot wingspan prototypes have been delivered. The prototypes were produced to explore and validate the structural, aerodynamic and operational advantages of the BWB concept and were designated X-48B by the U.S. Air Force based on its interest in the design's potential as a future military aircraft. The X-48B's three turbojet engines will allow the 500-pound, composite-skinned, 21-foot wingspan prototype to fly up to 120 knots and 10,000 feet in altitude during flight testing.
