I like a window but I'm not sure I want to see through the whole fuselage:

Heavens Above: Airbus Engineers' Plan For the Future Of Flying - SPIEGEL ONLINE - News - International (http://www.spiegel.de/international/zeitgeist/0,1518,718062,00.html)

What will air travel look like in the year 2050? A special team of engineers from European aircraft manufacturer Airbus have drafted plans for the future of flight. These include a completely transparent fuselage that will allow passengers to the see the stars above and city lights below.

The airplane dissolves into thin air, as if erased by an invisible hand. First the cabin roof disappears, then the floor, and from one moment to the next, the passengers feel like they have lost their grip on anything solid.

But the men and women on board, more than 300 of them, don't fall out of the sky. Instead, they continue their relaxed flight through the clouds. If they look above, they gaze into the sea of stars that is the Milky Way. When they look down, they see the glittering lights of the cities below.

Right now, a transparent airplane like this one is nothing more than a technological fantasy, in which the plane's outer skin would be made of a special futuristic type of ceramic. The push of a button would send electricity flowing through the material, rendering it transparent.

A Plane from Out of Science Fiction

"Passengers in an airplane like this would experience flight in a completely new way," enthuses Axel Krein, 49, head of research and technology for European aircraft manufacturer Airbus. The unconventional idea came from the special team that Krein himself put together to forge ideas for the airplanes of the future.

"We told our engineers to give their imaginations free rein," Krein explains. "What emerged were completely realistic visions of flight in the year 2050. Our people are grounded in reality, after all. And most of the necessary technology already exists."

Still, from a current perspective, some aspects of Airbus' "Concept Plane" sound so utopian, it seems only a descendent of Jules Verne could have conceived of them.

Self-Cleaning, Self-Repairing Plane

For example, another idea involves an aircraft outer skin that can repair itself. The moment that sensors detect a hairline crack anywhere in the aircraft, microscopic nano-capsules containing a high-tech adhesive would be released to seal the fissure. "The airplane almost becomes a living organism this way," Krein says.

Airbus' developers also envision the air travel of the future as an exceedingly clean affair. Nano-materials would allow seats to clean themselves, a system more hygienic than employing cleaning crews -- and far cheaper. "In the future," Krein suggests, "each passenger will feel he or she is sitting on a brand new airplane about to take off on its maiden flight."

Anti-turbulence sensors could make a further contribution to passenger comfort. These would detect unpleasant air pockets ahead, allowing the aircraft to adjust its navigation automatically, without assistance from the pilots, and the passengers to glide gently through the air.

A Flying Tadpole

The engineers' most important goals are reductions in fuel consumption and jet engine noise. In order to achieve these aims, they are planning a revolution in aircraft construction. The engines would be embedded into the fuselage, instead of located under the wings. With a more aerodynamic shape and framed by a curved tail plane, these engines would make for a more streamlined aircraft, as well as directing most of their noise upward. "Passengers will hear hardly any engine noise," Krein says, "and the same goes for people on the ground."

This design poses just one disadvantage -- the engines aren't easily accessible, making frequent maintenance essentially impossible. "In any case, we assume we will be using nearly maintenance-free engines by 2050," Krein explains.

The unusual shape of the fuselage -- Airbus' "Concept Plane" looks something like a flying tadpole -- will also reduce fuel consumption significantly. The fuselage shape contributes additional lift, as do the longer, narrower wings.

If the Airbus engineers have their way, future passengers may contribute to reductions in fuel costs themselves -- without even realizing it. Passengers' body heat would be collected and fed into onboard systems using heat exchangers.

But this isn't as futuristic as it sounds: There's a precedent for this sort of use of body heat. For centuries, farmers have built their barns to allow warmth from the cows to heat the farmhouse.

Whatever about the Airbus concepts, but the Finnair guys (see the photo gallery) are clearly on crack....:}

Caption No.1"We told our engineers to give their imaginations free rein," explains Axel Krein, head of research and technology for Airbus
Caption No.2"what emerged were completely realistic visions of flight in the year 2050. Our people are grounded in reality, after all."So ... since he already knows what is "completely realistic" for 2050, he did not need to ask them to use their imaginations. They just had to draw what is already known.

Sorry to be so literal but, they are engineers, so they will want to use words accurately and without ambiguity.

Caption No.3"...they are planning a revolution in aircraft construction."Oh, now we're back to new ideas are we?

Caption No.4The engines would be embedded into the fuselage, instead of located under the wings. With a more aerodynamic shape and framed by a curved tail plane, these engines would make for a more streamlined vessel ...Oh, you mean like the Comet - designed in the 1940s?

At least the Finnair folks REALLY gave "their imaginations free rein" :ok:

In the case of the transparent plane, assuming it's the skin that becomes transparent, wouldn't you see the inner workings and wiring of the aircraft if you looked up and the same plus your suitcase if you look down or are they going to somehow make those transparent too? But then again, it couldn't just be the skin. It would have to be the cabin walls/ceiling etc too or it would only be of interest to those on the ground watching what would appear to be a load of luggage hanging under a plastic tube with no wings bumbling around the sky. And I'm not even going anywhere near the thought of what the toilets would look like from either aspect....:ooh:

Can you tell I'm not an engineer? :O

What happened to the wedge? Even Airbus design still looks like a steel tube!

I think the last picture of the Boeing space capsule with the passengers stacked wouild prove very popular with Michael O Leary
