Possible Design Of The 737RS

Mon Apr 23, 2007 9:43 am

Just a fun post about what you guys think about this aircraft and if this could be a similar design of the upcoming 737RS. all opinions are welcome. I personally think this would be an awesome design, like a miniature 787. After all, boeing already has the technology from the 787.

Panelized metal construction, square windows and a square-tube fuselage?

Nope, don't see it.

And don't even seriously consider those engines...  Wink

Sure, why not. Several reasons.

1) Simple construction just to slap panels together.
2) Keeps the Volvo look to have everything square and ugly.
3) Always nice when history repeats itself. Maybe the Comet disasters inspired them.

Hmmm... The engine nacelles look like something that Airbus tried on one of their A32X for a test. The shark fin is back again. If such a plane is made, the shark fin will go away again.

As for the windows, come on guys, square is in! Forget safety! OR, they have decided that they won't pressurize it.  Smile

The interior leaves something to be desired. For those wondering what I am talking about, it appears that they won't have one. When you are checking in for the flight, you will have the option of, "Wing Box" or the "Belly". Looking through the windows, it looks like you can see the wing going through to the other side.  Smile

I think that when Boeing does finish the design for the 737RS, it will most likely be like 2 or 3 main pieces to stick together. Just imagine, if they plan on being able to pump out 787s every few days, 737s will be coming out like a PEZ Dispenser.

Other then some of the details, kind of a cool looking jet!

A fuselage like this would give excellent shoulder room. The pic doesn't look all that bad.

fat lipped engine would make a difference to fod damage maybe? over short distances maybe a squared fuselage is more efficient even with thicker corners. Think about it, you can fit seats in better and have less of a space under the floor as peeps dont tend to take many bags with them on the shorter flights. less wasted space=more rev. The window shape is strange but it might have nothing to do with pressure bearing structure.

The sugar scoop intake is probably for reducing fan noise heard on the ground, but it would interfere with airflow at high aoa.

That is correct. And the proper term is "scarfed inlet". Don't laugh. All airframers and engine makers have considered this as method of reducing noise.

Looks like the offspring of the 787 and an E-190. I doubt the square windows would make it to a final design due to past history regarding square windows on pressurized a/c. What would look interesting on that a/c idea would be the rounded triangular windows like the Caravelle had.

They need to change those windows with the rounder ones, if they don't want to risk a structural fatigue related crash like with the original Comet I.

I still like this concept best, basically a baby 787 with blended winglets... and tall ones at that!

I don't understand this. I must have missed something, but where does Volvo come into the 737 design?  Confused

Good looking design! I'd prefer the Gulfstream oval shaped windows myself.

Any idea when we'll see what Boeing has up their sleeve on the 737RS? scratchchin

There is absolutely nothing wrong with square windows provided they are properly engineered. Aircraft have traditionally utilized circular windows because they require less reinforcement and are therefore lighter than square windows. But if an OEM was willing to sacrifice the weight or found a material with the necessary strength properties that there was no significant weight penalty, there is nothing to fear.

For the sake of curiousity, would for example CFRP be strong enough to support square windows without risking structural fatigue?

I actually like Volvo's, especially the new S60, it has a new design with rounder shapes.

Back to topic, the aircraft looks ugly. Is it really under development ? It looks horrible, really.

I would personally say yes. If you look at the 787 and A350, both OEM are offering much bigger windows than current aircraft because the strength properties of CFRP allow the larger windows without compromise.

But as a truism, I suspect you could always make a larger cicular window for a given material than what would be possible with a square frame. In that regard, I agree that windows should always be rounded if for no other reason than to maximize viewing area.

Regarding the engines, since engine manufacturers started applying Lighthill's 8th power law there's been little they can do to reduce engine noise. The vast majority of noise reduction has come from low specific thrusts. As fan diameters reach their maximum, other advances have to be made to keep up with expect sound reductions. Things like exhaust chevrons, inlet chins and acoustic lining all have a really minimal effect on jet engine sound compared to what was achieved by applying the work of the man himself.
