Boeing Rolls out Static Test 777-9X

jayunited · Thu Sep 13, 2018 12:13 am

Even without paint and engines this aircraft looks great.
Hopefully at some point in the distant future UA will order this aircraft.

This was posted in the 777X development thread but this could warrant its own thread.

This plane does look really nice. I like how the wings look.

B752OS · Thu Sep 13, 2018 1:15 am

How long will the testing take? 6 months?

Waterbomber · Thu Sep 13, 2018 1:21 am

That wing looks like it was designed in TLS. The dihedral looks like a logarithmic graph.

bunumuring · Thu Sep 13, 2018 1:24 am

Hey guys,
It appears that the wingtip fold mechanism is in the 'open' position : ie wing tips "up"?!?!
I hope that Qantas FINALLY orders the 777 : the -9 to replace the A380 long term and the -8'SP' for Project Sunrise.... And maybe even a couple of 777freighters eventually, wink!
Cheers,
Bunumuring

I can't hardly see the wings in that picture, what good is a thread without more eye candy, lifted from the other thread.

To be honest, in the first few pics: if I didn't see the wingtips, I'd have thought it was just another 77W.

But in that last pic, with it inside and pointed to the left:
HOLY CRAP, that wing is **ENORMOUS** :eek:

Seriously, that thing is gonna generate some LIFT.

Not really that much more lift over the current 777 (a bit as the 777-9 is somewhat heavier). Those wings are going to really reduce fuel burn... and operating cost.

Have a great day,

I'm sure the wing will offer significant improvement on field performance as well.

kaitak744 · Thu Sep 13, 2018 8:30 am

Is the plan to still offer an 8 door version of the -9 for airlines with less dense configurations? (As opposed to the 10 door configuration on this test frame).

Or will it be like the 737-900ER, where you get the door anyways, and just block it off?

I'm not sure if this is legally possible due to the maximum distance from any point to the next exit. What is it? 30ft or something like that?

I remember a thread here about the A340-600 and the additional overwing exit that had to be added during certification because of that.

Edit:
According to the official ACAP (https://www.boeing.com/resources/boeingdotcom/commercial/airports/acaps/777-9_RevA.pdf) the 5th exit is optional.
But in the same document the distance between door 2 and door 3 is 63 feet. That is close on the limit.
Door 3 to door 5 is 62 feet.

The 8 door version will be standard, the 10 door version is optional.

1) Four Type A (for an Exit Limit of 440 seats)
2) Three Type A and One Type C (for an Exit Limit of 385 seats)
3) Three Type A and Two Type C (for an Exit Limit of 440 seats)
4) Four Type A and One Type C (for an Exit Limit of 475 seats)

(Doors are per side so total exists would be twice that)

Hope UA gets a big discount after all the static testing-to-destruction

Just teasing... I think it would be a great aircraft for all the US3 who have otherwise shunned any kind of VLA. Maybe it's a good flagship for all of them.

That wing looks so thin in post #8, perhaps a techie can expand on modern wings and comment on how that picture exemplifies them. One is almost tempted to say Boeing is using condensed gas, no room in that wing for regular.

JAAlbert · Thu Sep 13, 2018 2:02 pm

Quite the beauty even all wrapped up! The folding wingtips are much smaller than I anticipated, it will be something to see taxiing about the airport.
I am surprised at the distance between doors 1 and 2, it looks like this plane will have room for a large premium cabin.

Ziyulu · Thu Sep 13, 2018 2:19 pm

I'm guessing it will be 3-4-3 seating at 18" seat width due to the wider cabin?

It is presented as 19,7" with armrests, 17,2" between armrests.

That's mostly due to short distance between camera and wing tip (or in other words: due to wide angle lens affects). With wingtip up (as in that last pic), span is roughly the same as 77W.

Wow! Impressive. I'm impressed with the length. For sure the 777-9X is the longest twin ever designed in aviation history, if you exclude the A35J. Also interesting to see the structure inside the wings, near the wing root on the fuselage.

I'm surprised BA hasn't ordered any. I know Lufthansa did.

QuarkFly · Thu Sep 13, 2018 4:34 pm

I like the transparent carbon-fiber that lets you see inside to the ribs through the top of the wing !!

But I'm surprised the vertical stab is not part of a static test since it is rigidly attached...but maybe it is still coming and will be installed later.

Eh???
Are you saying the A35J is longer than the 779?
If you are, is your tape measure made in some 4th world country or you are into "alternative facts"?
779 = 76.7m.
A35J = 73.78m.

Does the static testing have to be completed before first flight?

No, but the plane will not start doing extreme load testing until the static test frame has been tested to Limit Load and Ultimate Load.

Door 3 to door 5 is 62 feet.

62+ft distance given on the ACAP is between the centerlines of Doors 3 and 5. These doors are 3.5ft wide so subtract 3.5ft from the centerline distance and the length between exits is slightly below 60ft.

AFAIK Boeing hasn't changed plans to make the 5th door (door 4) optional. Note also that, even when installed, door 4 is a smaller exit type that adds only 35 to the limit for 475.

I don't see many operators going for 475 given the trends in longhaul seating. Even though economy will likely stay 10ab for everyone, the premium cabins are taking more and more room.

Have a great day,

Currently, both the 77W and the 779 have an MTOW of 351.5t so required lift will be identical. 779 takeoff speeds should be lower though.

Are Type C's the smaller type of exit some airlines have on 763's aft of the wing?

That is a Type I Exit (with the other three pairs being Type A).

QXAS · Thu Sep 13, 2018 10:48 pm

Just as we needed a new term for the A380, big twin doesn’t seem to cut it for this jet. Everything about it is huge. Well, except the fuel burn. When will the official rollout and first flight be? And where is the rollout aircraft in the production process? Can’t wait to see the videos of those wings getting flexed to the limit.

I was expecting the folding wing tips to look bigger. They nearly look like a winglet.

It looks so small and simple I dont see why it hasnt been done earlier. It would not surprise me if the 797 gets folding tips to squeeze into gates that cn fit an A321. Or the A321 gets rewinged with folding tips in 10 years time.

The folding wingtip is actually a relatively small part of the wing. People worrying about problems with it likely didn’t realize how only a tiny part of the wing folds.
