Cooling plenums
« on: November 23, 2005, 02:23:53 AM »
Does anyone know about the possibility of  Making cooling plenums like Bill James has except for updraft cooling ?   What type of material did he use ?  It would be great to be able to maintain safe CHT's while taxiing or doing ground tests.

Not for updraft, but I have some good photo's and descriptions of what Mike Davis did for my plane with downdraft.

Send me an email if you want a copy of the .doc file.

Take a look at Bill's articles on ez.org ("Those EZ Chronicles" link on the left).  The one named "Plenty of Plenums" describes the materials he used.  I assumed he found some exotic material in the dumpsters at Lockheed but it turned out to be 3 layers of BID and EZ Poxy plus a few post cure cycles.  Maybe a little high temp BBQ paint to make it look exotic?

Haven't seen/heard anything about adapting the idea to an updraft config, though.
