The AWWA Air Whale, 750 pax in three classes

I loved it, I guess - I fell for the marketing. Looks great - and a little alien. If it does get to production, I hope that they don't shave away the 'alien' natures of the design. Loosing those small accents on the 787 kinda hurt from an aesthetic value. I miss those days of new designs and fascinating new combos. However, I then scrolled down to the comments. Hurrah for humanity? They tore the thing apart. Intelligently. Now, I feel the same way - it's quite futuristic, no? The technological advances necessary would make this aircraft not possible for at least two or three more decades. Feasible then? Sure? Maybe.
We didn't get the Sonic Cruiser. I don't think that we'll get this. Sadly - boringly and sparingly forward we go. Haha, safely and slowly.Whatever is necessary, is never unwise.

Same for Europe.
You can try to have more than two aisles, but then it makes it unlikely to evac the number of people serviced, within 90 seconds, from only half the exits.

Originally posted by LUNN View PostI think vertical take off and landing aircraft are needed to do away with runways and allow them to land anywhere in emergencies.
Why? Because VSTOL equipment only helps you during the 30seconds or so that you're taking off or landing.... otherwise, it's pure deadweight on 8, 10, 12, or 16hr+ longhauls.
And let's not even talk about how ridiculous the requirement in energy would be to get a 400ton+ widebody off of the ground vertically, versus the 13-16ton fighter jets who use it today.
No way. So long as we're using fossil fuels to power aircraft, the tradeoff isn't there, at all.

Advances are being made;
Following the first successful solar flight around the world, the Solar Impulse Foundation is now selecting clean and profitable solutions to environmental issues.
...and with them will come new solutions.
When we first invisioned airports, this is what we thought of;
I don't agree with LUNN, but I can understand that he is thinking ahead, to a future in which some of the common issues and realities that we face now will be irrelevant.Whatever is necessary, is never unwise.

The problem that I see with this "sky whale" is not related to accepting innovation and the future.
New materials? Sure.
New energy sources? Why not?.
New engine technologies? I'm sure.
Now, can anybody please explain me the advantages of this configuration?
- The shape of the fuselage.
- The "blended wings" that is mentioned in the text or the "detached wings" seen in the images.
- The engines integrated in the wing.
- The 2+2 engines config.
- The 45° rotating engines.
I can imagine that, as long as the planes remain subsonic, all the future technologies in materials, fuels, engines and systems will be applied to a conventional plane. More years have passed since the early pax jets than from the Wright Flyer to the first jets, and while planes changed a lot form the Wright Flyer to, say, the 707, current jets still look a lot like a 707. There is a good reason why the basic configuration of the jet airplanes remained grossly unchanged since the early ones (or since the DC-3 for the matter):
- A long wing is the most efficient way to make lift. Anything else that makes lift (like the fuselage) will incur in an induced drag greater than what an additional piece of the existing wing would.
- A round fuselage (or a combination or round lobes) is the most efficient way to carry payload in a pressurized vessel. Leaving the sphere aside, which has obvious practical constrains, any shape other than a cylinder will increase the weight and hence reduce the payload or range of the plane.
- Engines must receive free, undisturbed airflow, must be accessible for maintenance, must be designed with future upgrades in mind (look the constrains the Boeing has with the 737), and must take into account the survival of the plane in case of a catastrophic fire or damage.
A 750 pax plane with state-of-the-art technologies applied? Sure. It will look like a 380 or 777.
I mean, come on, we don't need to wait that long.
In fact, the A380 cabin is certified for 853 pax and 20 crew (in an all economic class config). So the 750 figure of this whale is not jaw dropping at all. I know, in 3 classes, and the 380 normally takes 300+ fewer passengers than its certified limit in 3 classes. But remember that this is the first version of the 380 and the plane was designed from the beginning with longer fuselages versions in mind. And in my opinion, a 3-class 750 pax A380 will be more efficient than this sky whale.

Upon not finding one I have to assume that the poor deluded soul means what he says !!

Originally posted by AA 1818 View PostOnce, we thought that regular flight (as we know it today), was impossible.
It's the exact same issue that supersonic pax travel faces-- it's not impossible at all, we could do/build it today, if we wanted. But we won't.
And that's because (as was actually said) the economic tradeoff isn't there, with anything resembling the energy sources available today or even in the most remotely-foreseeable future.
That's a fact, not an opinion.
Originally posted by AA 1818 View PostDaily, despite the extraction industry's powerful lobbying, we are moving further and further away from fossil fuels.
So perhaps you can quantify it with something more empirical than a few token examples? I'll wait....

With all due respect, and pardon the pun, Brian is a big boy. How about we let him fight his own battle...Whatever is necessary, is never unwise.
