Team Uses Historic NASA Tunnel to Test Blended Wing Body
An historic NASA wind tunnel is helping to test the prototype of a new, more fuel-efficient aircraft design.
Boeing Phantom Works, St. Louis, Mo., has partnered with NASA's Aeronautics Research Mission Directorate and the U.S. Air Force Research Laboratory, Wright Patterson Air Force Base, Ohio, to explore and validate the structural, aerodynamic and operational advantages of an advanced concept called the blended wing body or BWB. A BWB looks very different than most airplanes flying today. It's a modified triangular-shaped wing.
The team has produced two high-tech, 21-foot wingspan prototypes of the BWB for wind tunnel and flight-testing. The Air Force has designated the vehicles as the "X-48B" based on its interest in the design's potential as a multi-role, long-range, high-capacity military aircraft.
"One big difference between this airplane and the traditional tube and wing aircraft is that -instead of a conventional tail - the blended wing body relies solely on multiple control surfaces on the wing for stability and control," said Dan Vicroy, senior research engineer at NASA's Langley Research Center in Hampton, Va. "What we want to do with this wind tunnel test is to look at how these surfaces can best be used to maneuver the aircraft."
X-48B Ship No. 1 began wind tunnel testing April 7 at the Langley Full-Scale Tunnel at NASA Langley. The Langley Full-Scale Tunnel, operated by Old Dominion University in Norfolk, Va., was built in 1930 and has been used to test everything from World War II fighters, to the Mercury capsule, to concepts for a supersonic transport and now a blended wing body prototype.
When testing is completed in mid-May, the prototype will be shipped to NASA's Dryden Flight Research Center, Edwards Air Force Base, Calif., to serve as a backup to Ship No. 2, which will be used for remotely-piloted flight tests later this year. According to the team, both phases of testing are focused on learning more about the low-speed flight-control characteristics of the BWB concept.
"The X-48B prototypes have been dynamically scaled to represent a much larger aircraft and are being used to demonstrate that a BWB is as controllable and safe during takeoff, approach and landing as a conventional military transport airplane," said Norm Princen, chief engineer for the X-48B program at Boeing Phantom Works.
The Boeing, NASA and the Air Force Research Laboratory (AFRL) cooperative agreement on the X-48B program culminates years of BWB research by NASA and Boeing. AFRL is interested in the concept for its potential future military applications of the concept.
"We believe the BWB concept has the potential to cost effectively fill many roles required by the Air Force, such as tanking, weapons carriage, and command and control," said Captain Scott Bjorge, AFRL’s X-48B program manager. "This research is a great cooperative effort and a major step in the development of the BWB. AFRL is inspired to be involved in this critical test program."
Cranfield Aerospace Ltd., Cranfield, England, built the ground breaking X-48B prototypes to Boeing Phantom Works' specifications. Made primarily of advanced lightweight composite materials, the prototypes weigh about 400 pounds each. They are powered by three turbojet engines and can fly up to 120 knots or 138 miles an hour as high as 10,000 feet in altitude during flight-testing.
Cranfield Aerospace also provided the ground-control station. That's where a pilot will remotely control the X-48B during research flight tests.

Boeing Phantom Works to Lead Research on X-48B Blended Wing Body Concept
HAMPTON, Va., May 04, 2006 -- In cooperation with NASA and the U.S. Air Force Research Laboratory, the Phantom Works organization of Boeing [NYSE: BA] is taking another step toward exploring and validating the structural, aerodynamic and operational advantages of a futuristic aircraft design called the blended wing body, or BWB.
Two high-fidelity, 21-foot wingspan prototypes of the BWB concept have been designed and produced for wind tunnel and flight testing this year. The Air Force has designated the vehicles as the "X-48B," based on its interest in the design's potential as a flexible, long-range, high-capacity military aircraft.
X-48B Ship No. 1 began wind tunnel testing on April 7 at the Langley Full-Scale Tunnel at NASA's Langley Research Center. When testing is completed in early May, it will be shipped to NASA's Dryden Flight Research Center in California to serve as a backup to Ship No. 2, which will be used for flight testing later this year.

NASA also is committed to advancing the BWB concept. NASA and its partners have tested six different blended wing body models of various sizes over the last decade in four wind tunnels at the Langley Research Center.
"One big difference between this airplane and the traditional tube and wing aircraft is that -- instead of a conventional tail -- the blended wing body relies solely on multiple control surfaces on the wing for stability and control," said Dan Vicroy, NASA senior research engineer at the Langley Research Center. "What we want to do with this wind-tunnel test is to look at how these surfaces can be best used to maneuver the aircraft."

Powered by three turbojet engines, they will be capable of flying up to 120 knots and 10,000 feet in altitude during flight testing.
Boeing also contracted with Cranfield Aerospace to provide the ground-control station, in which a pilot will remotely control the X-48B during flight research testing.
As part of Boeing's long-range business strategy, its Phantom Works advanced research and development organization defines and develops innovative technologies and systems such as the blended wing body concept to meet future aerospace needs.
