Boeing To Begin Ground Testing Of X-48B Blended Wing Body Concept
Edwards CA (SPX) Oct 30, 2006 In cooperation with NASA and the U.S. Air Force Research Laboratory, Boeing Phantom Works soon will begin ground testing of its X-48B Blended Wing Body (BWB) concept 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. They were designated the "X-48B" by the U.S. Air Force based on its interest in the design's potential as a future military aircraft. "Earlier wind-tunnel testing and the upcoming flight testing are focused on learning more about the BWB's low-speed flight-control characteristics, especially during takeoffs and landings," said Norm Princen, Boeing Phantom Works chief engineer for the X-48B program. "Knowing how accurately our models predict these characteristics is an important step in the further development of this concept." X-48B Ship 1 completed extensive wind tunnel testing at the Old Dominion University NASA Langley Full-Scale Tunnel this summer before being shipped to NASA Dryden as a backup to Ship 2, which will be used for flight testing early next year. In preparation for first flight, the X-48B Ship 2 will undergo ground testing to validate its engine- and fuel-system integrity, battery endurance, telemetry link communication, flight-control software, and low- and high-speed taxiing characteristics. 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. The X-48B research project is led by Phantom Works, Boeing's advanced R&D unit chartered to provide innovative technology and system solutions to meet future aerospace needs. Cranfield Aerospace, Ltd., in the United Kingdom built the two X-48B prototypes for Phantom Works in accordance with Boeing requirements and specifications. NASA's participation in the project is focused on fundamental, edge-of-the-envelope flight dynamics and structural concepts of the BWB, while AFRL is focused on the BWB's potential as a flexible, long-range, high-capacity military aircraft.

Cool Under Pressure At The Cape Cape Canaveral FL (SPX) Oct 30, 2006 Drama builds as the countdown clock ticks down toward another space shuttle launch. Dressed in bright-orange protective suits and prepared for the mission, an elite group boards a van and the convoy heads to the launch pad where the shuttle awaits. But this crew isn't made up of astronauts headed for space. It's the "Ice Team." |
