There are some comments and notes with each case.  Take a look and if

inclinded I would greatly appreciate any feedback.

 

Ed;

 

I looked it over to maybe make some comments; but I don’t know what I’m looking at.  Maybe I missed because I haven’t read previous posts, but general questions are;

 

What sort of modeling is this, empirical or theoretical?  I don’t see any formulas in the spreadsheet.

What are the independant variables (input) and what are the dependant variables (output)?

Is this for a specific airplane? Fixed HE configuration?

Only specific point is the 35% penalty for “thick” radiator, but the thickness is fine as long as you have sufficient pressure recovery in the inlet duct to overcome PD across the core and other losses.

 

Anyway, I don’t expect you to write a manual, but if you have nothing else to do (yeah..right) educate me a little.
