2. CFD Using CMARC/Postmarc
Method for Modeling Rocket
Obtain stage length/diameter data from MAT code cases
Calculate wing/fin span/chord values
(wing for air launch case only)
Pick appropriate airfoil section for wing/fins
(currently using NACA 0012)
Edit Excel workbook that creates input files for CMARC with appropriate rocket dimensions
Excel workbook format created by Liaquat Iqbal (Ph. D. candidate, AAE 490A TA)

3. CFD Using CMARC/Postmarc
3-D CFD case takes ~13 seconds to run
Bottom Line: Faster CFD results for multiple launch configurations
Future Work
Work with MAT teams to collect rocket configuration dimensions
Work with Liaquat Iqbal on modifying Excel workbooks for different launch configurations
Run cases in CMARC/Postmarc
Example Postmarc Output
(Glider at 10 deg AoA)
