word from Renton buddies say the first three 787 test birds will be shredded for dust do to engineering issues, the plane needs a whole redesign.
 
I've heard that the floor beams kept getting destroyed during gear retractions. They had to redesign it resulting in a huge weight increase that negates a lot of range capabilities. At the moment, it can't do Newark to Hong Kong non-stop.
 
the 787 is a failure - was from the start and is now. just another example of boeing trying to shove a product down the customers throat - one the customer doesn't need. the 787 is nothing but a warmed over 777/767. it exemplifies how US corporations have become wrt "mba baby boomer children" (get the stock price up) running the show instead of the once great industry leaders who built aircraft (or any other technology for that matter) for love and passion. Mr Boeing is probibly rolling over in his grave seeing what his company (and other US aerospace/tech companies) are doing today. we are loosing our advantage fast.

the 777 should have been the last large twin engine "B-47" style airliner/aircraft built. the 787 should be a blended wing/ceramic engine/shark skin-canal aerodynamics configuration built with nano tech structors. our "mba leaders" can't seem to (have the vision) make the leap like the great industry leaders did with the DC-3/2 or 707/747 types.

it is a shame and pionts another finger at the USA and its growing list of problems. our aerospace is but one (albeit large) example. we are falling behind in all other areas of tech such as health (not as much) computer, chip, energy tech also. it can be directly linked to our societies focus on the almighty $$, the bling bling, mtv crib life. everyone wants the quick buck, nobody dreams of the product and lets the $$ come as a result. we have less and less enrollment in science/engineering and thoes that are enrolling are foreign. they are taking what they learn here and going back to asia and becoming the dreamers. it won't be long before the next Donald Douglas is Mr. Kim Sung Wong or the next garage tinkering Steve Jobs is Amier Haji. And by the way their companies in asia will not be outsoourcing their production to the USA.

Scary
 
There was a great article in Air & Space a while back about the 787.

This article went through how composites are made and how they are used on the plane..... The thing that stuck with me was the part about repairs. The writer went into a bit of detail about how skin patches are made to a conventional plane when a hole is poked in the skin-pretty routine on an aluminum plane-and very common.

The writer spoke to the engineers up there about how to repair the skin of a 787-what the tolerance is for a hole (size-wise.) Anyway, the engineer's response was "zero-but we will have spare plugs available." YGTBFSM!!!!!

Someone pokes a small hole in the fuselage and the design tolerance is "zero!" What the hell? Change out and entire fuselage plug for a pencil-size hole?????

I haven't researched this myself, but this makes it look like a complete disaster. If you have to change out one plug on one aircraft, it will cost far more than the entire fleet of 787s will save in fuel in a year!
-Can this be fact? If so-Boeing is gonna lose its butt on this thing!
-Amazing-if correct!
 
CRJ,

It can be repaired. Delta's been doing flight control surfaces in one of the World's largest composite repair shops for years.

More importantly, the design is very damage tolerant and better than composites designed thirty years ago on the airplanes we see on line. You whack aluminum with a hammer and it deforms. For the most part, you whack carbon fiber with a similar force and it bends, flexes and in an instant goes back into shape.

Please don't tell Honda, Hyundai, Toyota, or Nissan since they all have recently built factories in the United States.

Also, don't tell these guys:

and, by the way, from the Washington Herald:
The deal makes the 787 one of the industry's most successful launches ever. Boeing has now sold 790 Dreamliners even though the airliner has yet to take flight.

The company expects to test fly the 787 around the end of March and begin deliveries in late November or December. It expects to deliver 109 airplanes in 2009.

The 787, Boeing's first completely new jet since the 777 in 1995, will be the first large commercial airplane made mostly of carbon-fiber composites, a material similar to fiberglass that is extremely light and doesn't rust. Boeing says its new plane will be cheaper to maintain and offer better fuel efficiency and more passenger comforts than planes flying today.

Analysts called the demand for the Boeing plane unprecedented.
IMHO, the 787 does have problems, having mostly to do with managing labor and outsourcing. But, I'm inclined to think their engineers are amongst the very best and brightest in the business.
