OSH ...aluminum needs polishing. HELP!!
http://www.ionaircraft.com/Toucan.jpg
The GREEN (aluminum) parts need polishing. What's a good 1-2-3-4-5.... step process for polishing up the aluminum wings - for OSH? http://www.ionaircraft.com/engineering.html This will be my first time doing this, so don't skimp on the details please. Thanks in advance.

What are the wings bonded with? Will they safely withstand the internal temperatures they'll see in bare aluminum finish? Thanks, Bob K. |

I'm heading over to ION World Headquarters now (which Steve calls the left side of Al's hangar). Montblack I also need to head over to the airport and re-hang our "Blaine Aviation Weekend (May 19 - 20)" sign. It didn't like the 50+mph winds that blew through here the other evening. |

OSH ...aluminum needs polishing. HELP!!
I guess my memory of thermodynamics isn't what it never was. Isn't a
perfectly reflecting surface much better than one that doesn't reflect the energy? Like why snow doesn't melt very fast except when the bare ground shows through and then all of a sudden the snow is gone. Something about albedo, as I vaguely remember.

For details see http://www.soaridaho.com/Schreder/Co...olor_Temp.html Wayne HP-14 "6F" http://www.soaridaho.com/Schreder The following is from Bellcore. The first number is the solar energy absorbed the second is the low temperature heat radiation. As you can see, polished alumunum absorbs only slightly more than white paint but radiates only 6% as much heat. In other words, although it absorbs little, it radiates much less so it heats up more than any painted surface.

Montblack
True story. We had a Air Force General who wanted his personal aircraft to be polished aluminum so got a crew and they took all the paint off and polished bird up until it shined. Really looked snazzy. All the time bird was home in hanger there was a crew who polished it every day to keep shiny. After the General left the polish crew was pulled and in a short while the aluminum corroded and bird had to be Class 26'd (junked). So. If you want to keep polishing all the time then go ahead and polish the alclad off and the bare aluminum will corrode away. It's like a wooden boat where you have to keep working on the wood to keep it afloat. And the pointy end goes forward ) Big John ***********************************.
