CFD of R-27ER

[Cmptohocah]

I hope it's ok to share a post from a different category here.

Basically I've completed the first round CFD trials for the R-27ER missile and the results can be seen here:

It would be great if people can comment, verify and/or criticize my results/experiment.

The goal is get the most accurate results as possible, within reason that is.

Thank you in advance.

I ran my own CFD some time ago on a full 3-D model with tapered wings feel free to compare.  Now this was one of the first missiles I did which was on much older hardware so the mesh resolution was nowhere near as high for my latter stuff like the HARM and SD-10 which were both within 3%'ish of ED's stuff.  Additionally I didn't run the intermediate values around M1.0 (.95,1.05,1.1,1.15) so the shape of the curve left of the peak at M1.2 is probably not correct either.

This looks awesome. Do you have any 3D models to share? The one I used is accurate, dimension-vise, but as you have mentioned the flight surfaces are not fully modeled.

I did my tests in Autodesk CFD.

Also hit me up, if you are interested in contributing in any way.
