3rd AeroElastic Prediction Workshop High-Speed Working Group
Organized by ATA Engineering and supported by various entities including NASA, this workshop focuses on aerodynamics experiments and toolsets in the aerospace industry. Participants will discuss cases related to aeroelastic prediction and high-speed phenomena, aiming to share progress updates and present results for future meetings. The program includes sessions on administrative matters, workshop logistics, and expected outcomes. Attendees are encouraged to register for the workshop, which will feature presentations from all working groups.

Workshop Programmatics Results due end of October Details for both experiments available at AePW3 website https://nescacademy.nasa.gov/workshops/AePW3/public/wg/highspeed Monthly telecon slides posted as well Post-processing scripts also provided for to aid comparisons and ensure consistency of results Scheduled weekend before SciTech (Jan 21-22) SciTech is Jan 23-27 at National Harbor, MD No plans to provide virtual access to the workshop since hybrid approach hasn t been very effective in the past Must register for workshop and additional cost Cost is $300 (early registration) or $400 for AIAA members and $500 for AIAA non-members Can attend workshop without registering for conference Plan is to present all 4 working groups in serial Allow participants to see results from other WGs Presentations Current plan is 10-15 minutes for each participant (may vary depending on number of participants) Organizing committee will provide overview of cases for each WG so individual participants can just focus on presenting their results
Progress Updates RC-19 Open to WG HyMAX Open to WG Encountered any issues to share with WG?
ATA Using Subdomain Modeling Approach for RC-19 Fluid Domain When modeling entire wind tunnel, estimated Mach number in test section was ~2.2 (too high) Rather than use uniform inflow conditions at subdomain inflow Planning to scale M, T, and P to reported values Scaling based off centerline values and applied to all points on inflow plane Will preserve the reflected shocks present in test section Inflow Plane for FSI Domain FSI Domain 1.9 < M < 2.2 Pressure (Pa)
RC-19 Questions Response to questions from Kirk Brower/AFRL Double-click the image on left to open the PDF and see responses to all questions
HyMAX Questions Relative position of shock generator to test article is correct in CAD file Viscous vs inviscid mesh for shock generator? Left as choice to participants
Naming Convention Clarification Per email from Liam McQuellin 08/30 Originally the numerical value appended to the file name was specifying wedge angle of attack (alpha). We changed this to specify flow deflection angle (theta) but a version control issue on our end meant these updated files were not passed across to the working group. The numerical value in the CAD file name is now specifying the flow deflection angle
Test Stand Leading Edge Radius Per email from Liam McQuellin 09/12
Next Steps Collective AePW group meetings 1st Thursday of each month (currently on bi-monthly schedule) Next meeting is October 6th, 2022 @ 10:00 AM CT Please share with colleagues to increase participation
