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... :)

MPGuts-be-gone!
For all your driving out of cargo planes fuel efficiency concerns. |
I'm not even going to read the article- just popped in to award an A for artistic alliteration in the post title-I approve very much:)
|
Why, to lose all those dimply tripstrip like little vortex generators? :p
|
I think this falls in the splitting hair.. uh bugs catagory
|
But I already use Rain-X...

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. :mad::mad::mad::mad::mad:
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 mech |
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.
|
If the improvement is measurable it's worth pursuing, and no single paint company is going to see as much of a benifit as the end users.
Besides, NASA (and DARPA and other ends of the gubmint) have a long and productive history of performing or funding pure research that industry won't do because it simply won't show a profit in the next quarter or two. Tax money can be a very good thing. |
Couple years ago there was this big thing about baby powder applied to ths leading edge of your wing to prevent flow seperation or some such.
I see that has come back around. |

bug guts
In a press release tomorrow,NASA will say that they're going to reinstate DDT,kill all the world's flying insects,then they can reduce bug gut splattering 100%,and protect their pretty little laminar airfoils.:p

I thought the bees were a test run of that fuel efficiency program.

Airlines are already a near casualty. Government subsidies, bankruptcies to defraud employees, and killing off any high speed rail all in light of intractable fuel costs means the writings on the wall.
The only thing left in most businesses is government subsidization. Profit guarantee. Look at Elon Musk. That's his entire story. Our tax money at work building useless vehicles. Same people who thought Steve jobs a genius also elevate this guy. Both are/were good at storytelling, and that's about it. I'm told that in France it is only the poor who fly. The TGV is faster, more luxurious and without the indignities. Seems that train is the place for this coating. But we spend our money on wrong design war weapons, 1000 or more overseas military installations, and make parasites like Musk wealthy. As to bugs, yeah, wax and RainX work, but a short bottle of DAWN and ones own squeegee make fast work of clearing the glass (says this old truck driver). |
