Feel
comfortable sitting on the wings ?
坐在翅膀上感到安全嗎 ?
Look at this new aircraft....
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 within 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.
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 investment 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 0.88 or 654 mph
cruising speed, another advantage over the Airbus tube-and-wing designed A380's
570 mph.
The exact date for introduction is unclear,
yet the battle lines are clearly drawn in t! he
high-stakes war for future civilian air supremacy.
