{{Short description|Aircraft design with no clear divide between fuselage and wing}}
[[File:JetZero blended wing body aircraft prototype concept art.jpg|thumb|300px|A rendering of the [[US Air Force]] blended wing body aircraft project]]

A '''blended wing body''' ('''BWB'''), also known as '''blended body''', '''hybrid wing body''' ('''HWB''') or a '''lifting aerofoil fuselage''',<ref>{{cite book |title=A Dictionary of Aviation |first=David W. |last=Wragg |isbn=978-0-85045-163-4 |edition=first |publisher=Osprey |year=1973 |page=177}}</ref> is a [[fixed-wing aircraft]] having no clear dividing line between the wings and the main body of the craft.<ref name=burl/> The aircraft has distinct wing and body structures, which are smoothly blended together with no clear dividing line.<ref name="Crane">Crane, Dale. ''Dictionary of Aeronautical Terms, third edition''. Newcastle, Washington: Aviation Supplies & Academics, 1997. {{ISBN|1-56027-287-2}}. p. 224.</ref> This contrasts with a [[flying wing]], which has no distinct [[fuselage]], and a [[lifting body]], which has no distinct [[wing]]s. A BWB design may or may not be [[tailless aircraft|tailless]].

The main advantage of the BWB is to reduce [[wetted area]] and the accompanying [[form drag]] associated with a conventional wing-body junction. It may also be given a wide [[airfoil]]-shaped body, allowing the entire craft to generate [[lift (force)|lift]] and thus reducing the size and drag of the wings.

The BWB configuration is used for both [[aircraft]] and [[underwater glider]]s.

==History==
[[File:NASA N3-X hybrid wing aircraft.jpg|thumb|The N3-X NASA concept]]

In the early 1920s Nicolas Woyevodsky developed a theory of the BWB and, following wind tunnel tests, the [[Westland Dreadnought]] was built. It stalled on its first flight in 1924, severely injuring the pilot, and the project was cancelled. The idea was proposed again in the early 1940s for a [[Miles M.26]] airliner project and the [[Miles M.30]] "X Minor" research prototype was built to investigate it. The [[McDonnell XP-67]] prototype interceptor also flew in 1944 but did not meet expectations. The 1944 [[CBY-3 Loadmaster|Burnelli CBY-3 Loadmaster]] was a blended wing design intended for Canadian bush operations.<ref name=JAWA1947>{{cite book |title=Jane's all the World's Aircraft 1947 |editor1-last=Bridgman |editor1-first=Leonard |year=1947 |publisher=Sampson Low, Marston & Co |location=London|pages= 96c–97c}}</ref>

[[NASA]] and [[McDonnell Douglas]] returned to the concept in the 1990s with an [[artificial stability|artificially stabilized]] {{convert|17|ft|adj=on}} model (6% scale) called BWB-17, built by [[Stanford University]], which was flown in 1997 and showed good handling qualities.<ref name="Liebeck2004">{{cite journal |author=Liebeck, R.H. |author-link=Robert H. Liebeck |date=January–February 2004 |title=Design of the Blended Wing Body Subsonic Transport |url=http://www.vicomplex.hu/arep/BoeingBWB.pdf |journal=Journal of Aircraft |volume=41 |issue=1 |pages=10–25 |doi=10.2514/1.9084 |url-access= |doi-access=}}</ref>{{rp|16}} From 2000 NASA went on to develop a remotely controlled research model with a {{convert|21|ft|adj=on}} wingspan.

NASA has also jointly explored BWB designs for the [[Boeing X-48]] [[unmanned aerial vehicle]].<ref>[http://www.boeing.com/Features/2012/08/corp_x48_08_07_12.html "A flight toward the future."] {{webarchive |url=https://web.archive.org/web/20121204000341/http://www.boeing.com/Features/2012/08/corp_x48_08_07_12.html |date=December 4, 2012 }} ''[[Boeing]]'', August 7, 2012 Retrieved: November 23, 2012.</ref> Studies suggested that a BWB airliner carrying from 450 to 800 passengers could achieve fuel savings of over 20 percent.<ref name=Liebeck2004/>{{rp|21}}

[[Airbus]] is studying a BWB design as a possible replacement for the [[Airbus A320neo family|A320neo family]]. A sub-scale model flew for the first time in June 2019 as part of the MAVERIC (Model Aircraft for Validation and Experimentation of Robust Innovative Controls) programme, which Airbus hopes will help it reduce CO2 emissions by up to 50% relative to 2005 levels.<ref>{{cite news |last1=Reim |first1=Garrett |title=Airbus studies blended-wing airliner designs to slash fuel burn |url=https://www.flightglobal.com/singapore-air-show-2020/airbus-studies-blended-wing-airliner-designs-to-slash-fuel-burn/136662.article |work=Flight Global |date=11 February 2020 |language=en}}</ref>

The N3-X NASA concept uses a number of superconducting electric motors to drive the distributed fans to lower the fuel burn, emissions, and noise. The power to drive these electric fans is generated by two wingtip-mounted gas-turbine-driven superconducting electric generators. This idea for a possible future aircraft is called a "hybrid wing body" or sometimes a blended wing body. In this design, the wing blends seamlessly into the body of the aircraft, which makes it extremely aerodynamic and holds great promise for dramatic reductions in fuel consumption, noise and emissions. NASA develops concepts like these to test in computer simulations and as models in wind tunnels to prove whether the possible benefits would actually occur.{{cn|date=June 2021}}

=== 2020s ===
In 2020, [[Airbus]] presented a BWB concept as part of its [[Airbus ZEROe|ZEROe]] initiative and demonstrated a small-scale aircraft.<ref>{{Cite press release |url=https://www.airbus.com/en/newsroom/press-releases/2020-09-airbus-reveals-new-zero-emission-concept-aircraft |publisher= Airbus |date=21 September 2020 |title=Airbus reveals new zero emission concept aircraft}}</ref><ref name=AvWeek1jun2023>{{Cite news |title=Opinion: Why It Is Time For The Blended Wing Body |work= Aviation Week |url=https://aviationweek.com/aerospace/aircraft-propulsion/opinion-why-it-time-blended-wing-body |date= June 1, 2023 |author= Kevin Michaels }}</ref>

Following this development, JetZero has received [[Federal Aviation Administration|FAA]] clearance for test flights of its Pathfinder, a 'blended-wing' demonstrator plane designed to significantly reduce drag and fuel consumption. This innovative design could potentially lower emissions by 50%. Scheduled for full-scale development by 2030, JetZero plans to create variants for passengers, cargo, and military use. The project faces challenges in certification and integration with current airport infrastructures.<ref>{{Cite web |last=Prisco |first=Jacopo |date=2024-04-04 |title=JetZero: Groundbreaking 'blended-wing' demonstrator plane cleared to fly |url=https://www.cnn.com/travel/jetzero-pathfinder-subscale-demonstrator/index.html |access-date=2024-04-14 |website=CNN |language=en}}</ref>

==Characteristics==

The wide interior spaces created by the blending pose novel structural challenges. NASA has been studying foam-clad stitched-fabric [[carbon fiber composite]] skinning to create uninterrupted cabin space.<ref>{{cite web|last=Bullis|first=Kevin|date= January 24, 2013|title=NASA has demonstrated a manufacturing breakthrough that will allow hybrid wing aircraft to be scaled up |url= http://www.technologyreview.com/news/509916/hybrid-wing-uses-half-the-fuel-of-a-standard-airplane/|work=[[MIT Technology Review]]}}</ref>

The BWB form minimizes the total [[wetted area]] – the surface area of the aircraft skin, thus reducing [[skin drag]] to a minimum. It also creates a thickening of the wing root area, allowing a more efficient structure and reduced weight compared to a conventional craft. NASA also plans to integrate [[High bypass#Extreme bypass jet engines|Ultra High Bypass (UHB) ratio]] jet engines with the hybrid wing body.<ref>{{cite web| first1 =Michael | last1 = Braukus | first2 = Kathy | last2 = Barnstorff|date=Jan 7, 2013|title= NASA's Green Aviation Research Throttles Up Into Second Gear|url= http://www.nasa.gov/home/hqnews/2013/jan/HQ_13-002_ERA_Phase_2.html|access-date=Jan 26, 2013|publisher= [[NASA]]}}</ref>

A conventional tubular fuselage carries 12–13% of the total [[Lift (force)|lift]] compared to 31–43% carried by the centerbody in a BWB, where an intermediate lifting-fuselage configuration better suited to [[narrowbody]]-sized airliners would carry 25–32% for a 6.1–8.2% increase in [[Fuel economy in aircraft|fuel efficiency]].<ref name= "AW160822">{{cite web| first =Graham | last = Warwick|date=Aug 22, 2016|title= Finding Ultra-Efficient Designs For Smaller Airliners|url= http://aviationweek.com/commercial-aviation/finding-ultra-efficient-designs-smaller-airliners|work=Aviation Week & Space Technology}}</ref>

===Potential disadvantages===
*Evacuating a BWB in an emergency could be a challenge. Because of the aircraft's shape, the seating layout would be theater-style instead of tubular. This imposes inherent limits on the number of exit doors.<ref>{{cite book | first1 =E. R. | last1 = Galea |first2=L. |last2=Filippidis |first3=Z. |last3=Wang | first4 = P.

*A BWB has more empty weight for a given payload, and may not be economical for short missions of around four or fewer hours.<ref name="Leeham3apr2018" />
*A larger wing span may be incompatible with some airport infrastructure, requiring [[Folding wing|folding wings]] similar to the [[Boeing 777X]].
*It is more expensive to modify the design to create differently-sized variants compared to a conventional fuselage and wing which can be stretched or shrunk easily.<ref name= "Leeham3apr2018" />
*Pitch control and lift capability at low speed have presented challenges for blended-wing designs. JetZero has proposed a novel landing gear design to address these issues for its Z-5 BWB concept.<ref name="AW 21Apr2023" />
