General Objectives

  • Establish best practices for the prediction of S&C derivatives with RANS or DES – based CFD and to assess the limitations of these CFD methods when those best practices are applied
  • Provide an impartial forum for evaluating the effectiveness of existing computer codes and modeling techniques using RANS and DES solver
  • Identify areas in need of additional research and development

Focus of Workshop I

The inaugural workshop will use the ONERA version of the NASA/Boeing Common Research Model (CRM). It includes the wing, body and horizontal tail as well as a vertical tail designed by ONERA. This model has been tested in a wind tunnel with longitudinal test results having been published. There also exists unpublished data for this model at small sideslip angles. In this workshop, participant predictions of yawing moment, rolling moment and side force at sideslip will be compared to this unpublished data. Optionally, participants will predict the effects of the wind tunnel support sting on these moments and force.

Key Dates

Abstract Deadline Oct 1, 2020
Data Submittal Deadline Nov 14, 2020

Workshop registration will be handled through normal AIAA procedures.

Workshop presentations will not be official AIAA papers. However, a special session on stability and control prediction is planned for Aviation 2021 or SciTech 2022.

Test Cases

Case 1: 2d Code Verification Study
Case 2: CRM in Sideslip Grid Convergence Study (single condition on a family of grids)
Case 3: CRM Static Lateral Directional Stability (3 solutions on 1 grid)
Case 4: Wind Tunnel Sting Increments
Case 5: Stability Derivative Calculation
Case 6: Beta Sweep

Grids for all cases will be provided, but participants are encouraged to build their own grids using 'best practice' techniques. IGES and STP models are available for grid construction. Grid size requirements will be available on the workshop website. All grids used for results presented at the workshop must be submitted to the SCPW Organizing Committee to be made available to all interested parties.

General Information
