Future fodder for foolishness: bug splatter-shedding paint improves fuel economy!


Photo: Tamsin Slater


Actually, it's true! But for aeronautic applications...

Quote:
NASA scientists are now developing coatings that help aircraft shed or repel bug guts during flight. After screening nearly 200 different coating formulations [...] it has created a coating that could reduce the amount of insect insides stuck to the wings by up to 40%.

With further optimization, such coatings could allow planes to use 5% less fuel

Airplane Coatings Help Recoup Fuel Efficiency Lost To Bug Splatter

NASA’s insect-shedding surfaces reduce drag by keeping plane wings cleaner in flight


Airplane Coatings Help Recoup Fuel Efficiency Lost To Bug Splatter | June 29, 2015 Issue - Vol. 93 Issue 26 | Chemical & Engineering News

Countdown until this shows up on a car forum as a fuel economy mod?

That's pretty cool. I'm sure it would help for automotive vehicles... traveling at the same speeds...

For all your driving out of cargo planes fuel efficiency concerns.

I live about 20 miles from NASA Langley and find it astounding that NASA needs to spend my tax money when the Paint manufacturers should be doing this, without my tax money.

It just shows how insignificant they have become, a bunch of old farts like me riding their retirement plans to 80% (40 years).

They could help me with my idea instead of waxing and polishing a wings leading edge. Wonder how many billions they flush down the toilet on this?

I should not even read this thread and make my blood pressure spike, but then I guess you could call it a stroke test.

regards

With sufficient space to run up I suppose my car could cruise at 100+, but any efficiency gained would, of course, be lost to the speed demon.

Attempting such in the truck would necessitate paint that could shed bits of piston and crankshaft. The 22R is a dogged and relentless mill, but it is NOT happy at high revs.

A friend once told me that washing the bug splats off his airplane was good for about 2 MPH. His normal cruise speed was around 200 MPH.

22 Maverick: TBD
