Blended Wing Body
A blended wing body (BWB), also known as blended body, hybrid wing body (HWB) or a lifting aerofoil fuselage, is a fixed-wing aircraft having no clear dividing line between the wings and the main body of the craft. The aircraft has distinct wing and body structures, which are smoothly blended together with no clear dividing line.Crane, Dale. ''Dictionary of Aeronautical Terms, third edition''. Newcastle, Washington: Aviation Supplies & Academics, 1997. . p. 224. This contrasts with a flying wing, which has no distinct fuselage, and a lifting body, which has no distinct wings. 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 underw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CBY-3 Loadmaster
The Burnelli CBY-3 Loadmaster is an unconventional transport aircraft that was designed by American engineer Vincent Burnelli and built in Canada in 1944 by Canadian Car and Foundry. Design and development The CBY-3 " lifting fuselage" was an evolution of the earlier Burnelli UB-14. Burnelli worked as a designer at Canadian Car and Foundry (CanCar) in Montreal, and the CBY-3 was intended for bush operations in northern Canada. The sole prototype was extensively tested but failed to gain a production contract. Burnelli had a lifelong career devoted to exploiting the advantages of the lifting body airfoil concept that characterized many of his earlier aircraft designs. His last design, the CBY-3 was manufactured by CanCar in Montreal, but ownership reverted to Burnelli, when the CBY-3 was unable to gain a production contract. The name of the aircraft, CBY-3, was derived from the name of the three partners involved in its creation: CanCar, Burnelli and Lowell Yerex and "3" from ...

Airbus ZEROe
Airbus SE ( ; ; ; ) is a Pan-European aerospace corporation. The company's primary business is the design and manufacturing of commercial aircraft but it also has separate defence and space and helicopter divisions. Airbus has long been the world's leading helicopter manufacturer and, in 2019, also emerged as the world's biggest manufacturer of airliners. The company was incorporated as the European Aeronautic Defence and Space Company (EADS) in the year 2000 through the merger of the French Aérospatiale-Matra, the German DASA and Spanish CASA. The new entity subsequently acquired full ownership of its subsidiary, ''Airbus Industrie GIE'', a joint venture of European aerospace companies originally incorporated in 1970 to develop and produce a wide-body aircraft to compete with American-built airliners. EADS rebranded itself as ''Airbus SE'' in 2015. Reflecting its multinational origin, the company operates major offices and assembly plants in France, Germany, Spain, and th ...

Superconducting Electric Machine
Superconducting electric machines are electromechanical systems that rely on the use of one or more superconducting elements. Since superconductors have no DC resistance, they typically have greater efficiency. The most important parameter that is of utmost interest in superconducting machine is the generation of a very high magnetic field that is not possible in a conventional machine. This leads to a substantial decrease in the motor volume; which means a great increase in the power density. However, since superconductors only have zero resistance under a certain superconducting transition temperature, ''Tc'' that is hundreds of degrees lower than room temperature, cryogenics are required. History DC homopolar machines are among the oldest electric machines. Michael Faraday made a Homopolar motor in 1831. Superconducting DC homopolar machines use superconductors in their stationary field windings and normal conductors in their rotating pickup winding. In 2005 the General A ...

Airbus A320neo Family
The Airbus A320neo family is an incremental development of the A320 family of narrow-body airliners produced by Airbus. The A320neo family (''neo'' being Greek for "new", as well as an acronym for "new engine option") is based on the enhanced variant of the previous generation A319, A320, and A321, which was then retroactively renamed the A320ceo family (''ceo'' being an acronym for "current engine option"). Re-engined with CFM International LEAP or Pratt & Whitney PW1000G engines and fitted with sharklet wingtip devices as standard, the A320neo is 15% to 20% more fuel efficient than prior models, the A320ceo. It was launched on 1 December 2010, made its first flight on 25 September 2014 and was introduced by Lufthansa on 25 January 2016. By 2019, the A320neo had a 60% market share against the competing Boeing 737 MAX; in 2023, the Chinese designed Comac C919 joined these two as another direct competitor. , a total of 11,128 A320neo family aircraft had been ordered ...

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV) or unmanned aircraft system (UAS), commonly known as a drone, is an aircraft with no human pilot, crew, or passengers onboard, but rather is controlled remotely or is autonomous.De Gruyter Handbook of Drone Warfare; 2024. e-ISBN (PDF) 978-3-11-074203-9.H. Pan; M. Zahmatkesh; F. Rekabi-Bana; F. Arvin; J. HuT-STAR: Time-Optimal Swarm Trajectory Planning for Quadrotor Unmanned Aerial Vehicles IEEE Transactions on Intelligent Transportation Systems, 2025. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications. These include aerial photography, area coverage,F. Rekabi-Bana; Hu, J.; T.

Boeing X-48
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 X-48B was later modified into the X-48C version, which was flight tested from August 2012 to April 2013. Boeing and NASA planned to develop a larger BWB demonstrator, although no updates have been provided since 2013. Design and development Background Boeing had in the past studied a blended wing body design, but found that passengers did not like the theater-like configuration of the mock-up; the design was dropped for passenger airliners, but retained for military aircraft such as aerial refueling tankers."Design of the Blended Wing Body Subsonic Transport."''AIAA Journal of Aircraft,'' Volume 41, Issue 1, January–February 2004, pp. 10–25. * Norris, Guy and ...

Stanford University
Leland Stanford Junior University, commonly referred to as Stanford University, is a Private university, private research university in Stanford, California, United States. It was founded in 1885 by railroad magnate Leland Stanford (the eighth List of governors of California, governor of and then-incumbent List of United States senators from California, United States senator representing California) and his wife, Jane Stanford, Jane, in memory of their only child, Leland Stanford Jr., Leland Jr. The university admitted its first students in 1891, opening as a Mixed-sex education, coeducational and non-denominational institution. It struggled financially after Leland died in 1893 and again after much of the campus was damaged by the 1906 San Francisco earthquake. Following World War II, university Provost (education), provost Frederick Terman inspired an entrepreneurship, entrepreneurial culture to build a self-sufficient local industry (later Silicon Valley).
