Double bubble aircraft design would use 70 percent less fuel
The D double bubble design uses long, skinny wings, a small tail and - hence the name - replaces the traditional cylindrical fuselage with a two partial cylinders placed side-by-side. The engines sit at the rear of the fuselage rather than on the wing to make use of a technique called Boundary Layer Ingestion (BLI). This approach sees slower moving air from the wake of the fuselage enter the engines, resulting in less fuel consumption for the same amount of thrust. The downside is slower speeds and more stress on the engine.
The result is a plane that travels 10 percent slower than the Boeing 737 it is designed to replace, but according to lead designer of the D series Mark Drela, the longer flight times would be partially mitigated by the ability to load and unload the plane faster. Another advantage is that it could also be used with current airport infrastructure. Read more...

Pilotos ANA: primera tripulación de una aerolínea en pilotar el Boeing 787 Dreamliner
SEATTLE, 13 de mayo de 2010 – Boeing y dos pilotos de ANA (All Nippon Airways) llevaron a cabo un vuelo del Boeing 787 Dreamliner el pasado miércoles, convirtiéndose en los primeros pilotos de una aerolínea en pilotar un 787. El avión es el primero de los seis aviones que participan en los vuelos de pruebas. El vuelo de dos horas y cuarenta minutos se realizó sobre el estado de Washington. Los pilotos que se pusieron a los mandos del 787 por primera vez eran el Comandante. Masayuki Ishii, Director de Planificación pre-operaciones del 787, y el Comandante Masami Tsukamoto, Gerente de pre-operaciones de pilotos 787, ambos pertenecientes a la aerolínea japonesa ANA. Abordo se encontraban el Comandante. Mike Carriker, Jefe de Pilotos de Prueba del Boeing 787 y el Comandante Christine Walsh y Scott Fancher, Vicepresidente y Director General del Programa 787, Boeing Commercial Airplanes. "El vuelo fue una demostración comercial, que sirvió para que los pilotos jefes de nuestro cliente de lanzamiento evaluasen el 787," explicó Fancher. "Estamos muy orgullosos de tener a ANA abordo y poder así demostrar el gran avión desarrollado por los hombres y mujeres de Boeing." El vuelo se llevó a cabo bajo un certificado de aeronavegabilidad especial otorgado por la autoridad aeronáutica estadounidense (FAA). El programa 787 se lanzó en abril 2004 con un pedido récord de 50 787 por parte de ANA. ANA, que ha jugado un papel muy activo como cliente de lanzamiento, espera recibir su primer 787 en el cuarto trimestre de 2010. Durante el vuelo, ambos pilotos realizaron múltiples despegues y aterrizajes, junto con otras maniobras, lo que permitió comprobar las prestaciones del avión. Los pilotos también tuvieron oportunidad de experimentar otros aspectos de la cabina de mando del 787, incluyendo mayores pantallas de visualización, dos dispositivos head-up y dos maletas de vuelo electrónicas. "Fue una experiencia fantástica e increíble," declaró el Comandante. Ishii. "A los pasajeros de ANA les espera una experiencia increíble cuando vuelen en el 787," afirmó. "El vuelo fue fantástico," aseguró el comandante. Tsukamoto. "He esperado este día desde que ANA hizo su pedido y hoy mi sueño se ha hecho realidad." Durante el vuelo, Carriker explicó a los pilotos de ANA, ambos con habilitación de tipo del Boeing 777, las similitudes y diferencias entre los dos aviones. Se espera que la autoridad aeronáutica autorice un curso de diferencias de tan solo 5 días que permita habilitar a los pilotos 777 en el 787. Clientes en todo el mundo han encargado 860 787 desde el lanzamiento del programa en abril 2004, convirtiendo el Dreamliner en el nuevo reactor comercial más vendido de la historia.
Boeing increases 737 production rate
SEATTLE, May 17 /PRNewswire-FirstCall/ -- Boeing (NYSE: BA) today announced that it will increase production rates on the Next-Generation 737 program to 34 airplanes per month in early 2012. The planned rate increase is aimed at satisfying continued strong demand for the Next-Generation 737. In addition, the company continues to study further potential 737 rate increases, given continued customer demand. "With over 5,200 sold to date, the Next-Generation 737 is the workhorse in our customers' fleets around the world," said Boeing Commercial Airplanes President and CEO Jim Albaugh. "Even through the global economic downturn, our diverse 737 backlog has remained very strong. Increasing the 737 production rate is the right thing to do to meet the growth and fleet replacement needs of our customers." The current production rate on the 737 program is 31.5 airplanes per month. Suppliers for the 737 program are prepared to support the rate increase. The production rate decision is not expected to have a material impact on 2010 financial results. "The global economy continues to recover this year and we believe that airlines will return to profitability in 2011," said Randy Tinseth, vice president of Marketing for Boeing Commercial Airplanes. "We believe that there will be an increased demand for airplanes – especially in the market served by the Next-Generation 737 – in 2012 and beyond." With more than 2,000 unfilled orders from more than 80 customers around the world, the Next-Generation 737 is the newest and most technologically advanced airplane in its class. Airfinance Journal's investors' and operators' poll consistently ranks the Next-Generation 737 as the most preferred airplane in its class due to its wide market base, superior efficiency and lowest operating costs.
Lockheed Gives a Peek at New JSF Stealth Material Concept
It is called "fiber mat," and Tom Burbage, executive vice president of F-35 program integration for Lockheed Martin says it is "the single, biggest technological breakthrough we've had on this program."
He says that a new process to blend stealth qualities into composite material avoided the need for stealthy appliqués and coatings. Using a new process, Lockheed officials are curing the stealthy, fiber mat substance into the composite skin of the aircraft, according to Burbage. It "makes this airplane extremely rugged. You literally have to damage the airplane to reduce the signature," he said in an interview with Aviation Week in Fort Worth. This top-fiber mat surface takes the place of metallic paint that was used on earlier stealthy aircraft designs.
