Blended wing body is NASA's green focus
http://www.flightglobal.com/articles/2010/03/16/339194/blended-wing-body-is-nasas-green-focus.html
As rising fuel costs and pressure to cut emissions drive most of the aviation industry to seek even small improvements in aircraft efficiency, NASA is pushing to mature technologies that may realise in the 2020s an aircraft concept that could slash fuel consumption by up to a third.
The so-called flying wing, or blended wing body, is not a new idea. Serious work on the concept goes back to the 1940s, but only now with a coming together of composite material construction and computer-aided fly-by-wire control are its huge gains in aerodynamic efficiency realistically achievable Read more...

EADS batalla con EuroProp 500 millones de euros por los retrasos en el motor del A400M
Las reclamaciones legales con los proveedores van más allá del motor, pero la más importante es con EuroProp International. Con todo, fuentes del fabricante del motor, citadas por Aviation Week, afirmaron que el fabricante del motor señala a EADS como responsable de los retrasos ya que demoró la entrega de los datos necesarios para desarrollar el sistema FADEC (Full Authority Digital Engine Control), sistema con controla el motor y la hélice del avión. Además, Airbus Military debe a los proveedores el avance en los pagos, de manera que no está claro si las demandas se pueden anular entre sí.

Gripen NG Demonstrator flight tests in progress
The flight test programme with Gripen NG Demonstrator continues according to plan at the Saab facilities in Linköping. The latest flight, number 117 since the flight test programme started, was flown 2010-03-12.
2010-03-12
We are now testing all the tactical systems, such as the AESA radar and the new communications system. The test programme is very extensive, and the unusually harsh cold and snowy winter here in Sweden has challenged the programme schedule but we are now quickly catching up, says Mattias Bergström, the Gripen NG Demonstrator project manager.
We have finished, and successfully verified, the flight tests of the electro-optical Missile Approach Warning System (MAW) and the new fuel system with larger internal fuel tanks.
The Gripen NG is the next generation of the Gripen fighter, which is in service with the air forces of Sweden, the Czech Republic, Hungary and South Africa. It is also ordered by the Royal Thai Air Force and is flown by the Empire Test Pilots School, ETPS, in the UK.
Video: NASA's Ikhana UAV -- Predator B Expands Scientific missions
The aircraft, designed for long-endurance, high-altitude flight, has been modified and instrumented for use in multiple civil research roles.
NASA's Suborbital Science Program within the Science Mission Directorate is Ikhana's primary customer, using the aircraft for Earth science studies. A variety of atmospheric and remote sensing instruments, including duplicates of those sensors on orbiting satellites, can be installed to collect data during flights lasting up to 30 hours. The Suborbital Science Program uses both manned and unmanned aircraft to collect data within the Earth's atmosphere, complementing measurements of the same phenomenon taken from space and those taken on the Earth's surface.
