2010年2月11日 · The two X-48B Blended Wing Body technology demonstration aircraft were built by Cranfield Aerospace in the United Kingdom to Boeing’s specifications. The sub-scale prototypes have a wingspan of 20.4 feet, with prominent vertical fins and rudders at the wingtips and elevons along the trailing edges of the wings.

NASA has also jointly explored BWB designs for the Boeing X-48 unmanned aerial vehicle. [6] Studies suggested that a BWB airliner carrying from 450 to 800 passengers could achieve fuel savings of over 20 percent. [5]: 21 Airbus is studying a BWB design as a possible replacement for the A320neo family.

2020年12月7日 · This book details the remarkable efforts to develop a new aircraft configuration known as the Blended Wing-Body (BWB). Responding to a challenge from NASA, McDonnell Douglas Corporation initiated studies in the early 1990s to determine if this new configuration could bring about significant advantages over conventional sweptwing, streamlined ...

2023年8月23日 · With its spin parachute tail stinger extending aft, Boeing's sub-scale X-48B BWB technology demonstrator showed off its clean semi-triangular shape. The unique manta-ray shaped planform of the Blended Wing Body X-48B is evidenced as the subscale demonstrator soars over Edwards...

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. Boeing began flight testing the X-48B version for NASA in 2007.

The Blended-Wing-Body (BWB) concept has shown substantial performance benefits over conventional aircraft configuration with part of the benefit being derived from the absence of a conventional empennage arrangement.

X-48B是 NASA 和波音鬼怪工程部 (Phantom Works)共同合作的X飞机实验计划最新作品；翼身融合设计可比帅气的“塞拉旅馆” ( sierra hotel)战斗机更实用，能产生更大的升力、更小的阻力，以及具有更小的雷达反射截面，可说是创新世代的战斗飞机发明。

Blended-Wing-Body (BWB) concept evolved though a series of NASA funded design studies conducted by the McDonnell Douglas Corporation (later Boeing) during the early 1990’s.1,2 The concept has shown potential for improved efficiency over the classic tube and wing transport configuration with reductions in both takeoff weight and fuel burn.2 A ...

Propulsion installation design analyses, supported by CFD, were performed on a Blended Wing Body (BWB) aircraft with advanced, turbofan engines mounted atop the aft end of the aircraft.
