Snipped...

For these and other reasons surface heat exchangers are not too

promising.

Where would be the highest speed /lowest pressure in Perry's duct?

Anyone able to run a caculation exercise on the merrits of using this
speed/pressure as a suction pump to suck air through the regular

radiator?

The max speed in the duct should be quite a bit higher than the actual
aircraft speed. Would be great if you could use it! With a clean

circular

augmenter/extractor one might get away without losses and a net gain

with

the resulting smaller intake needed. If there is suction, a Naca intake
might have a place there too.
On a previous discussion it was mentioned, that this typ of intake was
designed for a suction typ airflow, wasn't it?
Well here we might be able to get that requirement!

Thomas you need Rhino :) I am not sure I follow what you are proposing.

Paul Lamar

Damn, I have Rhino! ...just no time to get to it! So far I didn't get past
the first half of the first Help tutorial! :(

Its a fast learning curve. Just jump in and start doing things.
Also ask me questions.
