Abstract
With the continuous progress in hardware and numerical schemes, Computational Unsteady Aerodynamics (CUA), that is, the application of Computational Fluid Dynamics (CFD) to unsteady flowfields, is slowly finding its way as a useful and reliable tool (turbulence and transition modeling permitting) in the aircraft, helicopter, and missile design and development process. Before a specific code may be used with confidence it is essential to validate its capability to describe the physics of the flow correctly, or at least to the level of approximation required, for which purpose a comparison with accurate experimental data is needed. Unsteady wind tunnel testing is difficult and expensive; two factors which limit the number of organizations with the capability and/or resources to perform it. Thus, unsteady experimental data is scarce, often restricted and scattered in diverse documents. Additionally, access to the reports does not necessarily assure access to the data itself. The present publication was conceived with the aim of collecting into a single easily accessible document as much of the good quality data as possible. The idea is not new. In 19%2 AGARD's Structures and Material Panel (SMP) produced the AGARD Report No. 702 'Compendium of Unsteady Aerodynamic Measurements', which has found and continues to find extensive use within the CUA community. Report 702 is primarily focused on aeroelasticity, with particular attention paid to transonic conventional flutter. In 1995 AGARD's Fluid Dynamics Panel (FDP) decided to update and expand the former database with new geometries and physical phenomena and launched Working Group WG-22 on 'Validation L)ata for Computational Unsteady Aerodynamic Codes'. Shortly afterwards AGARD was reorganized as the RTO (Research and Technology Organization) and the WO was renamed as AVT (Applied Vehicle Technology) WG-003.
