The cool tin is there to keep the air going all the way around the cylinder instead of just going between the cylinders and blowing straight down. The fins on the bottom of the cylinder would not see any air flow past them if the cool tins were not installed. Pretty much all aircraft engines I can think of have a cool tin type of arrangement.

Then, what is "cool tin" for, if not to cause turbulance, slow down the air, so it can pick up the heat??? See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2007 - KR Gathering There is a time for building and a time for FLYING and the time for Flying has begun. Daniel R. Heath - Lexington, SC -------Original Message------- Rough surfaces also cause turbulence in the cooling air flow which is not good. _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net please see other KRnet info at http://www.krnet.org/info.html
