I did some more computational fluid dynamic (CFD) analysis, this time of a
1950s era NACA research vehicle called the RM-10. It was used to research
supersonic aerodynamics. The page is at:

I am still waiting for a software upgrade to allow continued work on the
Alpha launch lug. Our present version will not allow me to mesh a fine grid
around the lug area to increase the accuracy of the solution.

But it _is_ rocket science!

Maybe model the launch lug as an inlet.

thanks for posting this - the RM-10 is really awesome looking. the cfd
is fun too.

Hi David,
What was the CFD code you used?
Fly straight and true (even on a computer)!

Looks like COSMOS Flo works to me...

Yup! Good eye Stephen! Our full time analysts use Fluent--I do more
structures work (ANSYS FEA) but like fooling around--er, TRAINING with
FloWorks!

Hi all,
We use Fluent and CFX for our little jobs (< 3million nodes), and a
home-grown code for the real ones (30-50 million) on 32-128 processors....
Compute straight and true!

Send him some samples to work with.
