NASA Tests Aircraft With Shape Shifting Wings

brad3378 Re:Aren't those just called FLAPS? (55 comments)

I STRONGLY disagree. This Is VERY innovative technology.

Flexture / compliant structural engineering is NOT trivial.
We're talking about a complex interaction of kinematics, material science, fatigue, structures, non-linear dynamic loads, and in this case even thermal loads because temperatures drop significantly at altitude and you're not going to want a brittle material failure. Not to mention the controls engineering and software required to control and monitor the structure or the exotic manufacturing processes required to make open celled structures. Are we talking about isotropic materials? Because if we're talking about composite materials, the complexity just became exponentially more complex. Did I even mention the Aerodynamicists role in this project yet?

Frankly, I'm having more difficulty trying to think of engineering displines that are *not* used by this technology.

Here's a "Simple" two dimensional cross section of a compliant wing design. http://www.topology-opt.com/wp...

In a real world 3D example, it's not likely that the 3D design would be a extruded version of the 2D profile.

brad3378 Stick Shift transmissions. (635 comments)

Manual transmissions are generally inferior to the new breed of efficient automatic transmissions, but there's an inexplicable thrill to having that extra control.

Ask Slashdot: What's New In Legacy Languages?

brad3378 Re:Still Waiting (247 comments)

I took a Fortran 77 class many years ago while pursuing my BSME, but never understood why we were using Fortran over more popular languages.

What's the advantage of Fortran in an engineering environment?

If I would have waited 10 years to attend college, I'd be way further in debt because tuition rates doubled.

Dutch Architect Plans 3D Printed Building

brad3378 Re:Cool - I just poured a building (74 comments)

You have a very interesting website. I especially liked your innovative re-use of your old Styrofoam. I wish I had mod points to give you.

I had no idea it took so much wood to tackle a project like that. How much money did you need to spend on wood for that project? Will you be able to reuse the wood after it is removed from the concrete? Do you think a 3D printed home would save on material costs after you factor in the cost of the wood?

Ford Building Cars That Talk To Other Cars

brad3378 Forget about talking to cars -Talk2 traffic lights (239 comments)

There's few things more irritating to me than waiting for a red light when there are no other vehicles at an intersection.
All I want is a simple way to communicate to the traffic light to let it know that I am approaching so I don't have to stop. It seems that most automatic lights I have encountered wait until I have come to a near full stop - which partially defeats the purpose.

Implement this and then BAM - instant time savings and 3+ Miles per gallon savings for every vehicle on the road.

NASA to spend billions to consolidate IT services

brad3378 brad3378 writes  |  more than 4 years ago

brad3378 (155304) writes "NASA has issued a final request for proposal for a menu of information technology services such as e-mail, security management, instant messaging and mobile communications. Estimates have pegged the work as worth $2.5 billion.

The project, Agency Consolidated End User Services (ACES), is designed to consolidate services across NASA into one agencywide solution. The requirements are currently met through the Outsourcing Desktop Initiative for NASA, the ODIN contract."
