AIAA CbA CoI Participants and Interested Individuals,
During our recent full-community meetings, several of you expressed interest in comparing deterministic results for a subset of the Challenge Problem flight conditions. The organizing team will gladly facilitate this comparison and to this end will be scheduling a meeting on September 10, 2026 at 10:00 am US Central Time - meeting details will be send out later and also published here. This will be an opportunity for Challenge Problem participants to assess the consistency of their deterministic results with other participants. The organizing team will anonymize the results (e.g., using A, B, C, … identifiers) and tell each participant what their unique identifier is before the meeting.
In order to minimize undue burden on the Challenge Problem participants and the organizing team making the comparisons, only a single flight condition has been selected. The chosen condition corresponds to the lowest lift value in the sweep of CL at cruise Mach; more specifically, it is the lowest CL value for the Group 1 set of cases in Table 2 of the Challenge Problem paper (AIAA 2025-3107).
Participants interested in submitting their deterministic results should consult the Excel spreadsheet available here. As indicated in the spreadsheet, please indicate the following information with your submission:
- Choice of structural model (simplified vs. full FEM)
- Interface loads for each of the 9 attachment points (both in N and lbs)
- Corresponding reserve factor for each of the 9 attachment points
Please submit your response to the organizing team via our email address below. We kindly request that you provide your data by September 4 COB so that we have time to compile it ahead of the meeting. If there are any issues with this date, please let us know.
