Airbus Takes Three-Star concept again

Airbus takes three-jet concept again on

TOULOUSE - which European aircraft manufacturers airbus has patent protection for a new three-jet concept at large-capacity aircraft requested. The European patent authority EPO leads the procedure under the announcing number 05783890,6, US the patent and office for mark USPTO under the file reference 20080073459. Airbus resumes a concept rejected since attitude the McDonnell Douglas MD-11 production in the year 1998 with the patent. An airbus speaker limited on request of aero.de however that the patent will not appear directly in the development of new airplanes. "the concept was already submitted beside many further in June 2005 for examination by the international patent authorities. Airbus requests regularly commercial legal protection for new developments of its engineers." The enterprise implements in the patent specification that aircraft manufacturers in the long-distance segment with exception of the airbus set A340, (A380) and the Boeing 747 up-to-date exclusively on twin-engine propulsion principles. The employment of this technology at larger model series causes that also the engines themselves ever larger and heavier become its. This circumstance made the aufwaendige construction of more stable bearing areas, chassis and trunk building groups necessary. Besides the noise emissions with development of the impulse work sizes rose superproportionally. The new three-jet concept represents a beginning to adjust these disadvantages. In the case of same total mass arise compared with machines with two engines an optimized weight distribution. For the tail units in the three-jet concept several construction alternatives to order, which could be used to an improvement of the aerodynamics in the fuselage area, would stand. Besides a third engine does not have to exhibit the same achievement parameters, how the fans fastened to the bearing areas, which increases the Flexibiltitaet in the conception of a new model. The Dreistrahkonzept was inserted for the first time into the 1970er years at long-distance machines of mass production. As typical representatives the Lockheed L-1011 tri star and the McDonnell Douglas DC-10 is considered to this building method.

In breve, airbus ha fatto richiesta alle autorita' europee preposte per depositare un brevetto per l'utilizzo del concetto di trimotore su aerei long-range. In airbus smentiscono pero' per ora piani di sviluppo di nuovi prodotti in tal senso.

I vantaggi deriverebbero da una riduzione di peso, consumi e inquinamento fonico rispetto ai quadrimotori.

Airbus files patent for updated tri-jet design

spacer-white.gif



Airbus (Toulouse) has filed a patent for the design of a new commercial trijet, reviving interest in a powerplant configuration abandoned by airliner manufacturers for over two decades. The patent application, which can be found here, shows a new trijet design featuring a distinctive, noise-shielding tail structure with two-vertical stabilizers. Airbus’ North American division stresses that the patent may not be relevant to the company’s future plans.
A statement was released saying, “Airbus is regularly filing patent applications and this is normal business for a company that is a leader in innovation and technology. That’s not to say this is ‘the’ design we’re looking at in the future - just one of a very many possibilities.” The tail structure and the third engine add weight and new structural complexity, but the manufacturer counters that a trijet design can still beat a twin-engined type on fuel efficiency through offsetting improvements. The added weight of the tail is largely compensated for the by the drop in the mass of the landing gear, the reason being that the landing gear is dimensionally smaller and less voluminous given the smaller engines.

allora vi tartassero di articoli in tedesco visto che in italiano viene tradotto il minimo!!!
Schade, peccato!

ma che dici?...l'italiano è una lingua sintetica:) e poi rispetto al tedesco ci si può fermare prima per capire, senza dover aspettare la fine della frase per trovare i verbi!:D
