Boeing's BWB -- a Super-Efficient Bat Jet

Boeing's BWB -- a Super-Efficient Bat Jet

Quote:
Boeing Co engineers have designed a super-efficient aircraft that would look like a giant bat and slash the cost of air transport.

The "Blended Wing Body" concept, outlined more than 10 years ago but now said to be almost perfected, would have no fuselage or tail. Rather, it would basically be a wing with a belly that would accommodate the passengers and freight.
Quote:
Boeing calculates that a BWB seating 480 passengers would use 32 percent less fuel than the proposed A380-700 from Airbus, the main business unit of European aerospace group EADS.

The plane would weigh 19 percent less, suggesting that it would cost less to build. And it would need 19 percent less thrust, saving on engine manufacturing and maintenance costs.

Needing less thrust, the aircraft would emit less pollution. And it would a lot be quieter, Boeing's research suggests.

Its shape could also give it a little more speed than normal jet airliners have.

Test flights of a revolutionary fast and fuel-efficient bat-shaped aircraft, suitable for military and commercial use, could begin in 2006, the president of Boeing research arm Phantom Works said on July 9, 2002. Boeing, in partnership with NASA, has been perfecting the Blended Wing Body which would do away with the traditional tubular and bi-winged structure, replacing it with a giant wing and hanging belly for passengers and cargo. A 3% scale model of the 450-passenger subsonic transport is shown mounted for static force tests at NASA's Langley Research Center's Subsonic Tunnel. (NASA via Reuters)

Really low, I wonder if you would even be able to stand.

Landing gear?

From the photos I've seen, this this is probably going to require quite tall landing gear to avoid smacking the tail on the ground turning takeoff. It looks as if the center of gravity isnt very far back, meaning the gear will be almost mid-plane.
