Re: Ultimate Static Test

The video you provided was for just the wing box.  The ultimate static test I referred to was for the entire airframe.

This video is the one from Nova of the 777.  24 feet deflection.  The test destroyed the wiffletrees used to load the wing.  What a great test, with all that energy released in an instant.

They do have a 787 test-to-destruction video at: http://www.youtube.com/watch?v=sA9Kato1CxA

As a former Boeing employee (1962 to 1964 Helicopter Div.), I sincerely hope the 787 lives up to all its expectations.  Aircraft manufacturing is one the great exports from the United States.  Although many parts are made overseas, the main assembly is done in the US.  Fuel is an extremely expensive component of operating an airline.  A 20% more efficient aircraft has to be attractive.  I just hope the 3 year delay hasn't too severely hurt the overall program.

It is not correct to make a blanket statement that test and integration get no respect. These activities are dependent on design engineering and execute nearer to the end of the development life cycle. It is Program Management's fault for making 'made for success' schedules which guarantee broken milestones. Thus test and integration are always put into a time squeeze. It is only Program Management that has no respect.

More than a decade ago, Nova aired a terrific story about the development and testing of the 777.  It included a clip of the ultimate static test of the wing, bending up more than 23 feet before the incredible failure.  I hope we'll get to see that for the 787 and its composite wings.

These are exciting times for the space travel! I have been following SpaceX for several years now and remembered sitting at the computer in the early morning hours watching a live feed on one of their first launches of the Falcon 1 rocket. Wow!  Right there (so to speak). 

I know that many people bemoan the change of role for NASA but I really think it is so exciting that people such as Elon Musk see the challenge of commercial space travel and see that they can make some money at it. At times, I wish I was much younger and that I could participate in these activities. Ah, well - I'll just have to content myself with sitting on the sidelines and cheering them on.

The application of the new hybrid material technologies in the new Dreamliner is exciting to see.  Use of the carbon fiber for the wing construction may prove out the use of the material in many other high volume consumer products.

You're right, Alex, test and integration do get the least respect. But if ever a product proved that it shouldn't be so, it was the Boeing 787 over the past three years.

The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
Researchers have developed a new flexible fabric that integrates both movement and sensors, introducing new potential for technology-embedded clothing and soft robots.

The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
