maglev bridge or wing
The bridge (or wing) keeps perfectly still and unbowed despite high winds; the network of wires just underneath the bridge or wing sways wildly; nifty computers change the EM fields stiffening the bridge/wing dynamically | |
this is like an upside down maglev top.
Thre is a video of "galloping gertie" a bridge that comes
apart in high winds. Similarly I imagine airplane wings
might be more effective if not wind distorted. There is a
slight chance that with oodles of unexplained electricity
the wings could be
lighter as well.
underneath the wing/bridge their is a mesh of EM
producing computer controlled levitators, the kind that
dynamically balance a load, very similar to a maglev top.
just make a clever weave, or an array of maglev tops
underneath the wing/bridge. almost zero distortion
force
on the bridge/wing while even a wildly flapping EM mesh
microadjusts its fields. sort of like a maglev sheet
directly
under a wing, with maybe one mm of clearance.
Technologically of course the electricity to power this is
not obvious, unless you have one of those flying nuclear
reactor planes.

As far as I can tell, the proposal is to stabilise aircraft wings against bending, by means of magnetic fields. One problem with this is that the source of the magnetic fields will have to be fixed to a rigid, non-bending structure. However, this could be ground-based, as long as the aircraft doesn't do anything radical like leaving the ground. |

I find that just going ahead and using the entire atom, instead
of just the byproducts of moving its electrons, is more
efficient. In doing so, I get neat strong force benefits, and
can combine them in interesting ways, to make things like
steel, wood, and aluminum sheeting. Also I get the benefit of
avoiding creating random EMF noise that could interfere with
the plane's instrumentation, transponder signal, and all-
important Wifi hotspot feed. |

I'm not sure how this will work for a wing. I think artificial
muscles would be a better solution for active stiffness in
wings. |

For a bridge experiencing high wind, I'm concerned that it
will still oscillate (whether maglev or artificial muscles).
Oscillation is a difficult problem to solve: throwing active
correction at it often makes it worse. See pilot-induced
oscillation; the same phenomenon can still occur easily
when you use an artificial control system rather than a
human pilot. However, with proper tuning, I think it could
work. |

You might, maybe, perhaps, just possibly be able to damp out wing flutter using piezoelectric devices (is there anything they can't do?). But then you're dependent on the electrical system to maintain the otherwise flaccid wing in a flyable condition. Given that the in-flight entertainment system doesn't always work, I'm not sure I'd want to depend that heavily on electronics. |
