Extract From NASA Blueprint for the future
Revolutionary Vehicles: Development of supersonic aircraft capable of global travel to any point within 10 hr. and reducing transcontinental flight times by 50% are goals. Other technologies include creation of new materials, morphing airframe structures, micro surface actuators, intelligent and adaptive flight control systems, hybrid propulsion, hydrogen-oxygen fuel cells and advanced computational tools. Noise reduction of 20dB. and cutting engine emissions up to 50% are key priorities.

Excerpt from EUROPEAN AERONAUTICS: A VISION FOR 2020
Total engagement by the industry in the task of studying and minimising the industry’s impact on the global environment.
A reduction in perceived noise to one half of current average levels. Eliminate noise nuisance outside the airport boundary by day and night by quieter aircraft, better land planning and use around airports and systematic use of noise reduction procedures.
Goals
In 2020, aircraft are cleaner and quieter and the aeronautics sector’s contribution to a sustainable environment is widely understood and appreciated. Aircraft noise is no longer a political and social issue. It has ceased to be a nuisance to people living close to airports thanks to a concerted effort to develop quieter engines, optimise operational procedures and improve land planning and

There is now a new feature to the Alliedinter News web site. You can click on the comments and add your own feedback.Over the years there have always been complaints of inadequate commiunication between AIC NY and all of you out in the field selling our products. We do not advertise or list this site with search engines, but other people outside our community including competitors could conceivably stumble across it. We could make it a private site, but then you would have to log on with a username and password everytime. Personally, I recognize that we all have competing demands on our time and that almost everybody hates usernames and passwords.
Some government statistics on US trade in capacitors show tremendous growth on the import side. Eurofard Capacitors should find a profitable niche in this market.

Boeing/Rolls test new nacelles
Lärmminderung mit Sägezahnverkleidung
Boeing Commercial Airplanes and Rolls-Royce Aero Engines have completed a noise reduction flight test program that promises to make quiet jets even quieter. Known as the Quiet Technology Demonstrator (QTD), a Rolls Royce Trent 800 engine was modified with a package of noise reduction technologies developed collaboratively by the two aerospace companies. Using a 777-200ER, the three week flight-test demonstrated noise levels significantly below those of a standard 777, which is known as one of the quietest airplanes in service today. Takeoff jet exhaust noise was reduced by up to four decibels and inlet fan noise was reduced by up to 13 decibels. Engineers used saw-tooth-shaped aerodynamic devices at the rear of the nacelle and on the exhaust nozzle to control the mixing of the hot jet exhaust, the bypass stream and the ambient air. The shape of the devices was determined by computational fluid dynamics modeling and verified in wind tunnel tests using scale models. Fan noise also was reduced with extensive acoustic improvements to the redesigned engine nacelle inlet. A new technology called Amax (area maximization) increased by 30 percent the area of acoustic treatment in the inlet casing. A new lining design was used that reduces objectionable "buzz saw" noise passengers often hear during takeoff and climb. The flight tests, conducted at Boeing's Glasgow, Mont., airfield, verified the computer and laboratory results. Some 200

Lockheed whets Polish appetite for F-16 upgrade This is old news I turned up looking for something else. It bears looking into as we did very well with the SABCA NATO F-16 MLU program. Lots of new TRUs. Any body know anything about this program?
