No one will want it. It makes ignoring necessary safety protocols impossible if the problem is so visible

Hey heyyyy, Switzerland on the front page, and it's neither a scenic view, nor because we did a racism again. Great success!

Hey Switzerland is not only racism and scenery. There is also CERN.

This will inevitably be used for art at some point. Possibly even custom performance art with a sledgehammer and immediate art sales.

At least from the gist of this it could be used for waterproofing & be quicker to detect possible leaks, it could probably be heat shrinked

For an ultralight maybe, most plastics have too much creep under stress to make them viable structural components on an aircraft.

Wind turbines?

Well unless is has a lot of adjustability not wings as they are designed to flex but other airframe components yes. Gear struts, fan blades.

4 years ago | Likes 22 Dislikes 0

Everything on an aircraft is designed with permissible levels of flexure. Stiffness equals weight. Safety margins on components is 1.5 max.

This won't replace eddy current or ultrasonic inspections, it will just be a possible visual inspection for SOME components within specs

My thoughts went more toward identifying errors during the manufacturing process so as to better prevent escapements, but I agree with you.

Boy can't wait to be getting on a plane with wings that are half color changed but they're all like "it's still within regulations".

4 years ago | Likes 11 Dislikes 0

Average commuter airplane age is ~20-25 years. If "within regulations" is a concern for you, I have unfortunate news...

4 years ago | Likes 2 Dislikes 0

most plane wings can bend an absurd amount before damage occurs. most can go over 30-45 degrees.

4 years ago | Likes 10 Dislikes 0

Considering that the entire plane is literally hanging on the wings while flying, yeah those wings will change color on first flight proly

"...changes colour..." 3 completely red pictures...?

4 years ago | Likes 50 Dislikes 6

The title is misleading. It's a change in fluorescence, which is easier to distinguish than changes in color.

Darker isn't a color change? It's pedantic kinda true, no?

4 years ago | Likes 6 Dislikes 10

What you mean probably is this is not a hue change. But definitely a color change, as mentioned in the article.

4 years ago | Likes 1 Dislikes 0

Darker is absolutely a color change. Or are you saying that hues are not different colors?

4 years ago | Likes 4 Dislikes 1

'Hues' as i understand it is a synonym for 'color'. The HSB color system has Hue, Brightness, and Saturation. So in that, no, (1/2)

4 years ago | Likes 2 Dislikes 1

Shade is not a different color, but simply that, a different shade of the same color.

4 years ago | Likes 2 Dislikes 1

I honestly don't know? We perceive them as distinct things, isn't that a change, then? Either way, it's probably because it's in a red room.

4 years ago | Likes 2 Dislikes 0

If you need a color change to notice a "deformation" when it's bent 90° I think that's not as useful as the headline makes it out to be.

4 years ago | Likes 4 Dislikes 0

E.g., over several years, a metal beam flexes many times, appearing to return to normal shape. This apparently shows when fatigue sets in 1/
