Lockheed Martin lost one of two X-56A experimental vehicles yesterday.

www.edwards.af.mil...

Initial flight tests of the X-56A air vehicle #1, nicknamed "FIDO," were performed at Edwards Air Force Base, California, by personnel from Lockheed Martin and the Air Force Research laboratory in late 2013 and early 2014. Researchers collected flight data on highly flexible structures and flutter suppression control technology. A second vehicle, nicknamed "Buckeye," which has been on loan to NASA, is currently undergoing maintenance and upgrades. It is being used to explore significant advances in aeroservoelastic technology.

It is unknown at this time how the loss of FIDO is likely to affect both programs.

Damn, that has been doing interesting work. Is there any idea as to what happened?

Did you see the accident? Hopefully NASA has better luck with Buckeye.

You ever see the video of the Tacoma bridge where it was rocking and twisting, and eventuality collapsed?

Flutter.

Sympathetic Harmonic vibrations is another.

That's the more complex way to put it. I find the bridge analogy works well.

I get sympathetic ringing better. anology fits perfectly with my right hand muting technique when playing bass. if I hit a "g" on one string the open "g" string will vibrate sympathetically. gotta control that to be a master of your situation I guess.

cool.

zaph the bridge example is a good way to visualize what they are seeking to eliminate with the x56 studies. efficiency, and finess not a bad thing to possess.

as a bass player I totally get it.

x56 must be very illuminating for the guys working on it. sorry to hear about one them went down.

I can only imagine the implications of the knowledge gained from studying that phenomena and getting it squared away

There's still a car with a three legged cocker spaniel at the bottom of the Tacoma narrows to this day because of flutter.

I always felt bad for the dog.

Would reducing or eliminating flutter have much bearing on breaking the 8 minute barrier?

Someone can correct me if I'm wrong but isn't the 8 minute barrier more of a materials/heating problem?
