Teijin to supply carbonfibre materials for Airbus aircraft

Teijin, a Japanese synthetic textile maker, has signed a long-term deal with Airbus' parent EADS  to supply carbonfibre and carbonfibre-based materials for various passenger aircraft models.

The first phase would see them supplying a laminate of carbonfibre reinforced thermoplastic resin, which is undergoing trials for use on the upcoming Airbus A350


Pratt & Whitney F135 Propulsion System Achieves Historic Supersonic Success

EAST HARTFORD, Conn., June, 28, 2010 – The Pratt & Whitney F135 propulsion system has powered the Lockheed Martin F-35B Lightning II Short Takeoff and Vertical Landing (STOVL) variant through another major program achievement, with the first supersonic flight of the STOVL F-35B aircraft. Pratt & Whitney is a United Technologies Corp. (NYSE:UTX) company.

"This is truly a historic accomplishment, not just for Pratt & Whitney and the F135 team, but really for all of military aviation," said Bennett Croswell, Vice President of F135 and F119 Engine Programs. "This is the first time ever, in the history of aviation that a production ready, stealthy, short take-off vertical landing capable aircraft has flown supersonic."

Piloting the aircraft (BF-2) was U.S. Marine Corps Lt. Col. Matt Kelly, who climbed to 30,000 feet and accelerated to Mach 1.07 in the off-shore supersonic test track near Naval Air Station Patuxent River. BF-2 is the third F-35 to fly supersonic. Two F-35A conventional takeoff and landing variants also achieved supersonic speeds.

"We are proud to celebrate this milestone with our partners at the Joint Program Office and Lockheed Martin, and look forward to continuing to expand the envelope of this truly remarkable aircraft and propulsion system," Croswell said.

The Pratt & Whitney F135 continues it's steady progress through conclusion of development testing and validation, and into full production and sustainment The F135 has completed more than 17,600 hours of testing and the Conventional Takeoff and Landing (CTOL) / Carrier Variant (CV) engine received Initial Service Release (ISR) in February indicating that the engine has met all the ISR requirements for safety, reliability, durability and performance, and that it is now cleared for use in the field. Pratt & Whitney has delivered all test engines required for the program as well as the first four production engines.

Pratt & Whitney, the only engine manufacturer producing fifth generation propulsion systems, has designed, developed and tested the F135 to deliver the most advanced fifth generation fighter engine for the U.S. Air Force, Marine Corps and Navy, as well as for eight international partner countries.  The F135 is derived from proven technology of the only operational fifth generation fighter engine, the Pratt & Whitney F119 that exclusively powers the F-22 with more than 300,000 engine hours.  It has been further enhanced with technologies developed in several Air Force and Navy technology demonstration programs.
The F135 propulsion system has proven through extensive ground and flight test experience that it can meet diverse aircraft requirements, for armed forces around the world. The Pratt & Whitney F135 engine continues to be the only engine powering the successful Lockheed Martin F-35 Flight Test Program.

FAA Selects Pratt & Whitney for CLEEN Technologies Program, Targets the Environmentally Friendly PurePower(R) Engines

Press Release

The Federal Aviation Administration (FAA) announced today that Pratt & Whitney has been awarded a one-year contract with extension options, which will assist Pratt & Whitney to further develop and mature new jet engine technologies aimed at reduced fuel burn, noise and emissions under the FAA's Continuous Lower Energy, Emissions and Noise (CLEEN) technology development program. 

WASHINGTON, D.C., June 24, 2010 – The Federal Aviation Administration (FAA) announced today that Pratt & Whitney has been awarded a one-year contract with extension options, which will assist Pratt & Whitney to further develop and mature new jet engine technologies aimed at reduced fuel burn, noise and emissions under the FAA's Continuous Lower Energy, Emissions and Noise (CLEEN) technology development program. The funding will support ongoing development of advanced technologies for the new game-changing PurePower engine family with the geared turbofan™ architecture. Pratt & Whitney is a United Technologies Corp. (NYSE:UTX) company.

Under the CLEEN program, the FAA will support the development and commercialization of CLEEN technologies for current and future civil subsonic airplanes and jet engines to help achieve the Next Generation Air transportation System (NextGen) goals. These goals are intended to increase airspace system capacity by significantly reducing the impact of noise and air quality emissions on communities.

The CLEEN program's goals include the maturation of new aircraft technologies for introduction beginning in 2015. The goals include reduction of aircraft fuel burn by 33 percent below current technology, reduction of noise by 32db cumulative below Stage 4 levels, and reductions of NOx emissions by 60 percent below CAEP 6 standards. Pratt & Whitney will work to further advance jet engine technologies to achieve additional fuel, emissions and noise benefits through 2025.

"The PurePower PW1000G® engine, which is scheduled for entry into service in 2013, already enables Pratt & Whitney to deliver world class levels of fuel burn, noise, and emissions," said Alan Epstein, Pratt & Whitney vice president, Technology & Environment. "Unlike conventional turbofans based on existing technology that have been stretched to its limits to achieve added efficiencies, the geared turbofan engine technology has runway and should achieve fuel burn savings of 25-35 percent by the 2020s. The gear changes everything."

The PurePower family of engines is designed to power the next generation of passenger aircraft. The combination of its gear system and advanced core allows PurePower engines to deliver double-digit improvements in fuel efficiency and emissions with a 50-percent reduction in noise over today's engines.
Pratt & Whitney's PurePower PW1000G engine has been recognized by Popular Science Magazine with a 2009 "Best of What's New Award." In addition to the Popular Science award, Pratt & Whitney's PurePower engine family also received the 2009 Aviation Week Laureate Award for outstanding achievement in Aeronautics and Propulsion and the 2008 Technology Breakthrough Award from the China Aviation Association and AVIC Science and Technology department.

Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines, space propulsion systems and industrial gas turbines. United Technologies, based in Hartford, Conn., is a diversified company providing high technology products and services to the global aerospace and commercial building industries.

Aviones no tripulados para sofocar los incendios que asolan España

El empresario se puso a trabajar en el proyecto con el único apoyo financiero de algunos amigos y sin ningún conocimiento aeronáutico, pero con una visión clara: "Un pequeño avión con una cámara térmica puede ver una barbacoa a 15 kilómetros. Se trata de una herramienta potentísima para detectar cuanto antes un foco y evitar que se propague. Hasta ahora, la vigilancia se hace con torres y aviones tripulados, que tienen un coste seis veces superiores al nuestro", señala Gayá, que hace años estuvo vinculado al sector de los medios de comunicación

El resultado de ese sueño es Flightech Systems, una pequeña empresa que ha desarrollado su propio avión no tripulado (UAV) y que se encuentra a un paso de conseguir un hito en la industria: lograr que Aviación Civil le conceda el primer permiso para operarlo con fines civiles. "Tenemos desde febrero un certificado de aeronavegabilidad especial experimental -Gayá muestra orgulloso el documento-, que nos ha permitido hacer las pruebas.
