لوالله يا جماعة الخير لقيتها بموقع اجنبي ونقلتها لكم.. 1000 راكب ,, راحت على الايرباص..,,
Boeing diseña un jet para 1000pasajeros que podría marcar la nueva tendencia de la industria del transporte aéreo para los próximos 100 años. Un diseño mixto con mezcla de ala volante ha sido desarrollado por Boeing en cooperación con el Centro de Investigación de NASA en Langley. El gigantesco avión tendrá una envergadura de 265 pies (el 747 tiene 211 pies), y su diseño esta pensado además para que quepa en las terminales creadas recientemente para el A380 que tienen 262 pies de ancho. Por tanto los nuevos 797 serían la respuesta directa de Boeing al A380 .
Boeing se decidió a tirar al cesto de papeles su proyecto del estirado 747X en el 2003 luego del poco interés que éste despertara en las compañías aéreas del mundo, pero ha continuado desarrollando el proyecto 797 por años en su Phantom Works Research Facility en Long Beach, California.
El Airbus A380 ha estado en desarrollo desde 1999 con un costo acumulado de U$D 13 mil millones, dándole a Boeing una enorme ventaja ya que Airbus ha confiado en un avión tubular al más viejo estilo con décadas por venir donde se esperan cambios radicales.
Existen grandes ventajas en un diseño tan radical, la más significativa es el cociente de elevación, que con el peso total reducido un 25%, se espera aumente a un 50%, haciéndolo estimativamente un 33% más eficiente que el A380. La gran rigidez del cuerpo es otro factor dominante en la nave de diseño mixto, reduciendo la turbulencia y creando menos tensión en el aire lo que agrega eficacia, ya que permitiría a los enormes 797 con sus 1000 pasajeros, una autonomía de 8800 millas náuticas, a una velocidad crucero de .88 mach, unas 654 mph/1046 kph (otra ventaja sobre el Airbus A380 que con su diseño alcanza las 570 mph/912 kph)
Su fecha exacta de lanzamiento es confusa, pero se dibuja claramente en el horizonte una gran guerra por la supremacía civil del aire.
Look at this new aircraft...guess we are not going to be outdone by the French A380. Boeing to take on Airbus with (1000 seat) giant 797 Blended Wing plane Boeing is preparing a 1000 passenger jet that could reshape the Air travel industry for the next 100 years. The radical Blended Wing design has been developed by Boeing in cooperation with the NASA Langley Research Center . The mammoth plane will have a wing span of 265 feet compared to the 747's 211 feet, and is designed to fit wi thin the newly created terminals used for the 555 seat Airbus A380, which is 262 feet wide.
The new 797 is in direct response to the Airbus A380 which has racked up 159 orders, but has not yet flown any passengers. Boeing decide to kill its 747X stretched super jumbo in 2003 after little interest was shown by airline companies! , but has continued to develop the ultimate Airbus crusher 797 for years at its Phantom Works research facility in Long Beach , Calif.
The Airbus A380 has been in the works since 1999 and has accumulated $13 billion in development costs, which gives Boeing a huge advantage now that Airbus has committed to the older style tubular aircraft for decades to come.
There are several big advantages to the blended wing design, the most important being the lift to drag ratio which is expected to increase by an amazing 50%, with overall weight reduced by 25%, making it an estimated 33% more efficient than the A380, and making Airbus's $13 billion dollar invest ment look pretty shaky.
High body rigidity is another key factor in blended wing aircraft, It reduces turbulence and creates less stress on the air frame which adds to efficiency, giving the 797 a tremendous 8800 nautical mile range with its 1000 passengers flying comfortably at mach .88 or 654 mph (+-1046km/h) cruising speed another advantage over the Airbus tube-and-wing designed A380's 570 mph (912 km/h).

The exact date for introduction is unclear, yet the battle lines are clearly drawn in the high-stakes war for civilian air supremacy.
*تنويه الخبر ليس اكيد 100%,,
لأن شركة boeing لم تفصح عن شئ الى الآن,, ولم تقم بعرض الطائرة اعلاميا,, ولكن الشركة بينت ان الطائرة الجديدة ستكون نقلة نوعية كبيرة في عالم الطيران,,
هذه المعلومات وجدتها بموقع اجنبي,, ونقلتها لكم,,
الخلاصة: انه اذا بكرة طلع شكل الطائرة الجديدة غير هذا الشكل<<< ترا انا بريئ :iconloli:
