Boeing sees gains in the 787 Dreamliner

A shark tooth edge on the rear of the engine casing dampens noise and more aerodynamically designed wing flaps, used during takeoff and landing, will help to reduce the 787's noise "footprint" to about half that of existing similar sized jets.

Lower noise pollution will allow airlines to fly into many airports with noise curfew restrictions more often or later into the evening.

The fire resistant properties of carbon fibre are also expected to improve the chances of passenger survival in a crash. Aluminium melts in about one minute in a post-crash fire.

Carbon fibre withstands a fire for more than five minutes, providing crucial time to allow passengers to escape, Mr Hawk says.

Boeing made an unexpected discovery during strength testing of the fuselage which showed cabin pressure was maintained even after a 30cm-long steel blade was fired through the aircraft skin.

The carbon fibres had remained interwoven, in effect resealing the hole, even when pressure was increased.
 
WOO-HOO:nana2: :nana2: :nana2: :nana2:
Boeing is the ish!!!!!!!!!!!! I'm glad REAL advancements/improvements are going to be in a Boeing product.
 
Yeah the Carbon Fiber takes longer to burn, but it give off a yellow toxic smoke that will knock you out before you burn.

The hull holding pressure after the hole is impressive.
 
What I find interesting is the reduced noise footprint & will the airport allow the airplane to land after curfew?
 
Any truth in the rumors of Boeing being the next Airbus in terms of delays for delivery of the 787?

I heard alot of people say that Boeing failed an important test and or cracks were found in the composite or that the composite structure wasn't as hard as Boeing had thought or promised. And thus delays will occur?

Any truth Mike or is everything on schedule?
 
Interesting. Try selling the idea on reduced noise impact to a community that was stupid enough to pass a curfew in the first place. Such places deserve to have Beech 1900's with Stuka sirens mounted on them flying over anyways...:insane:

Boeing is on time for the 787, from everything that I have read..

The crack that you referred to, was a test that Boeing was conducting on another way to cook the composites, that experiment failed, so, Boeing went back to the original plan.

Probably!

A lot of the noise restrictions don't apply to the MD-90.

The Godless Canadians are claiming that it's some Canadair jet that's the quietest, but the -90's got 'em beat.

Well Honeywell is right on the other side of I-10 and of course under the approach of runway 08. When on lunch and break when east ops are in affect we have all manner of planes flying low on approach.

Never seen/heard a DL MD-90 fly over the j-o-b. But plenty of CRJ's fly over and they are quiet and have a very distinctive noise footprint. It sounds like a very low pitched whistle. US Airways A320 series are very loud when flying over.

I thought maybe the difference in noise volume was the differnce between a plane having engines on the wing vs. a "T" tail design with the engines located farther back on the fuselage.

I interviewed a guy who owns a nanotech company here in Dallas recently for an article. One of the things he makes is an additive for composites that uses carbon nanotubes in this very proprietary soup that makes composites far stronger than without it. Pretty interesting stuff, and I wonder if Boeing has looked into/is using something like that.

Of course, if they'd just make the plane out of the same stuff as the Black Box then there wouldn't be a problem....:sarcasm:

I noticed that the other day. My office is located on the final approach path of Sunset at LAS and saw an MD-90 yesterday landing and it was pretter effing quiet.

Any pictures of the 787 yet? From the drawings it looks like the E-190 but bigger.

In Vegas, I will bring down some Product Cards of the 787.......

You heard any news about that new MD-12 MD is thinking about making which is the super stretch for the MD-11 with a new wing.

:sarcasm:

Okay..just got back from 1994.

Ha! At the Boeing archives, they have this cool model of the MD12, I was warned that if it shows up missing, they are going to my house first:nana2:

I heard the MD-12 if it had gotten MD board approval might have really turned things around at Douglas. Oh well...

Question Mike. There are 3 current members making up the 787 family the 3,8,9 and a proposed 10 model.

Is the 787 going to be larger then 777's in terms of size and have greater ranger capability? Or is the 787 going to be the medium range complement to it's long range 777 family brethern?

The proposed 787-10 will offer more seats, less range than the other 787 models. The 777 will be larger with more range/more seats.....

Boeing is being careful, not to cross over the 787 with the 777, though, the 787-10 would probably kill off the 777-200ER, which has seen its sales slow down anyway.
