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.
