I just haveing more fun with jetliners design.

I looked at how jetliner size went from DC-8 60s to 747s, and it has me thinking about, what type of jetliner would out size the A380. Seeing that it not that likely we would see a bigger airliner than the A380, I tought I just design one. Here we go, the a/c is the WW4070, she is a triple decker with the main area double deck and a 747 like hump for the triple deck area. She would be 339 ft long, with a wing span of 310 ft and a hieght of 98ft at the top of the tail. The WW4070 would have a cabin width of 30 ft on the main, deck 28ft on the second deck and 21 on the third deck. It would be powered by four engines with and 150 inch fans, let's say RR Trent 1800 or GP 92120 with thrust vectoring. It would have a wing swept of 39 degrees, and a cruising speed of mach 0.88. Now I know the WW4070 is a little over the top, but it would be cool if an airliner like this was built.

Supposing there was a market for such an aircraft, why would any engine company build such an engine, and why would you have thrust vectoring on it?

Arguably, the same can be of the A380's engines. I wonder whether either engine manufacturer can count on making break-even before another 5-10 years, if ever...

Well, no. The 777-300ER engines are way bigger than the 380 engines. From memory 115k lb of thrust compared to about 80k.

My bad, I had the impression we were talking about new engines other than the -115B.

Thrust vectoring eh? Why did you not choose to make the aircraft have stealth characteristics and maybe even ejection seats?

Did I really just find this is in Tech / Ops???



If it was said by us, then it must be true.

Come on give him a break! In 30 years from now when someone does build a plane like that, you will be eating your words

747400Sp: How many people will your plane accommodate? my guess roughly 700 + in 3 class configuration.

Also, would thrust vectoring make do away with the rudder?

Thank you Qsliinger

It will accomodate 800 + in an 3 class configuration. I did not think about the rudder, but having both trust verctoring and rudder. could not hurt to much.

You'd have to rewrite the FAR's to handle it...being uncontrollable in the event of an engine failure will not please the FAA.

Thrust vectoring?! Bonkers! But how about only having it on the outboards to maximise weight savings and to use the largest moment? I'd definitely keep the rudder... I'd be scared not having one...

If it's going to be triple deck plane I would put the flight deck between the first and second main decks like in the A380, and would turn the front section of the third deck in to a forward looking bar/lounge....either that or those would be the absolute best seats in the house....err plane.

Somebody please explain to me how having thrust vectored nozzles is lighter than a vertical fin, to say nothing of cost and/or complexity.

Well, I was just going with the spirit of the thread... I'm not in for a super-jumbo or thrust vectoring, personally.

I'm always up for bigger windows. I flew on a DC-9 recently and it was phenomenal compared to newer things...

It will need thrust vectoring to take off and land...or a really, really long runway....or...catapults...yeah...thats the ticket...

Well, lets take it in smaller steps; the follow on to the A388 is the A389. Putting aside economic viability, what would be the next step after that. Another stretch? A new model slightly bigger all around? Or would the next step require some really new technology -- BWB for example.

If you use the tinting system that's on the 787, it'd be just fine at all times.

What about bus style windows? Would those have any problems on an airliner?

Quoting 747400sp (Thread starter):
let's say RR Trent 1800 or GP 92120 with thrust vectoring.

Would they be 360 degree vectoring or only up/down or left/right?
