Paul,


I don`t know if you have seen this 1942 report on rammed air and scoop
profiles.

I am wading through it slowly.

Wow! They put a lot of effort into that. That is a very comprehensive study.

Based on this elbow performance investigation you can make certain judgments
about side ports verses p-ports.

Dave L. Download and read this. You might decide to redesign your turbo intake
manifold.

It is a real shame they did not scan these old NACA tech papers with higher rez.
They are barely readable. Your tax dollars at work.

Am I imagining it or does it seem like the quality of the research done
in the late 1940 to late 1950s is some what ... richer..?  Perhaps word
processors and computers short circuited our ability to clearly
articulate  research today.  Maybe it was more hands on type of research
then.

Certainly more useful for our purposes. Of course WW II helped.

After the war the gov. was looking for an excuse to tax more and spend big
bucks on useless manned space travel. Practical research of this kind suffered.
We would have turbo compound rotaries in a heart beat if they would just divert
the $500 million it cost to shoot the shuttle into space just once.

out of your paycheck!" :)
