The Boeing X-48 is an American experimental unmanned aerial vehicle (UAV) built to investigate the characteristics of blended wing body (BWB) aircraft. Boeing designed the X-48 and two examples were built by Cranfield Aerospace in the UK.

Apr 17, 2013 · The X-48C model, which was formerly the X-48B Blended Wing Body aircraft, was modified to evaluate the low-speed stability and control of a low-noise version of a notional, future Hybrid Wing Body (HWB) aircraft design.

Jun 8, 2013 · The X-48C is a version of NASA’s X-48B blended wing body aircraft modified to evaluate the low-speed stability and control of a low-noise version of a notional hybrid-wing-body design.

Sep 17, 2009 · “The other one we just tested in the Langley Full-Scale Tunnel is the X-48C. It’s been modified to make it even quieter. We’re assessing the aerodynamic effects of those modifications.” Those changes include reducing the number of engines from three to two and the installation of vertical fins to shield the engine noise.

Aug 7, 2012 · The X-48C is a scale model of a heavy-lift, subsonic vehicle that forgoes the conventional tube-and-wing airplane design in favor of a triangular aircraft that effectively merges the vehicle's wing and body.

Apr 12, 2013 · The X-48C is a modified version of the X-48B aircraft, which flew 92 times at NASA Dryden between 2007 and 2010. The X-48C is configured with two 89-pound thrust turbojet engines, instead of three 50-pound thrust engines on the B-model.

Boeing X-48C aircraft is an upgraded version incorporated with dimensions similar to those of the X-48B. The upgraded aircraft features new flight control system software and flight control limiters developed to keep the airplane flying within a safe flight envelope.

Apr 16, 2013 · Now that the X-48C’s tests have been completed, NASA and Boeing have announced plans to build a fourth blended-wing aircraft capable of demonstrating transonic flight.

Apr 15, 2013 · The X-48C Blended Wing Body (BWB, aka Hybrid Wing Body) research aircraft made its 30th and final flight as part of an eight month flight testing campaign last week.

Aug 7, 2012 · Edwards AFB, Calif. — The remotely piloted X-48C aircraft successfully flew for the first time Tuesday at Edwards Air Force Base in California’s Mojave Desert.
