An investigation of the aerodynamics and cooling of horizontally  

opposed engine installation" 

SJ Miley. SAE 1977.

  

 Hi Duncan,

  

 I found the report you cite here:

  

 http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19810013485_1981013485.pdf

  

 I think this is the same report, but it's date of issue shows 1981. I've  not had a chance to read it through yet, but skimming over it it looks to  contain everything anybody could ever want to know about recip engine cooing and  duct shape. Thanks for the heads up on that one! Our tax dollars might  have actually been used to produce something useful. Wouldn't that be a  breath of fresh air? 

  

 Gilles, in regard to the details of my Jab installation, I've not had a  chance to post anything yet. I have sent rather lengthy descriptions of what  I've done to those who have asked, though. If there is enough interest (and if I  can find the time) I could put together a report with pictures detailing my  installation. I'm still fiddling with several things at the moment, so it's  still a work in progress. So far, though, it's working well.

  

 I started playing with shapes yesterday to fair in the triangle  brace I mentioned on the nosegear leg. I looks like I can bend up something  out of sheet metal that would do what needs to be done in that area.

  

 Regards,

John

I tend to knock things up in sheet lead, easy to form and stretch. Then 

I use the part I've knocked up as a mould for a GRP copy. Tend to use 

phenolic resin around the back of the engine, its fire resistant. Not 

easy to get hold of in small quantities though.



I rarely have the discipline to do this, but I always say " one change 

at a time, then you have a chance of seeing if its better or worse" ?

That's the one!

 Only I had to pay 25 USD for mine and wait a couple of weeks.

 Dammn!

John, Duncan and all,



S.J. Miley has been with us since the beginning of our cooling project.

By the way, we made liberal use of the US tax dollars, by closely 

studying many NACA/NASA reports, some of them dating back to the '40s 

I tried to make as useful a summary as possible on cooling and internal 

aerodynamics.

Any pictures will be appreciated. I'm sure you'll come out with quite 
	


satisfactory cooling, though the quest may prove long since you're 

pioneering with the Jab installation.

All the best with your project,



Best regards,
