Book Description
The development and application of transonic small disturbance codes for computing two dimensional flows, using the code ATRAN2, and for computing three dimensional flows, using the code ATRAN3S, are described. Calculated and experimental results are compared for unsteady flows about airfoils and wings, including several of the cases from the AGARD Standard Aeroelastic Configurations. In two dimensions, the results include AGARD priority cases for the NACA 64A006, NACA 64A010, NACA 0012, and MBB-A3 airfoils. In three dimensions, the results include flows about the F-5 wing, a typical wing, and the AGARD rectangular wings. Viscous corrections are included in some calculations, including those for the AGARD rectangular wing. For several cases, the aerodynamic and aeroelastic calculations are compared with experimental results. Goorjian, P. M. and Guruswamy, G. P.

Book Description
The aeroelastician needs reliable efficient methods for the calculation of unsteady aerodynamic forces in the frequency critical transonic speed regime. The development of such methods can be enhanced by the availability of a limited number of test cases for the comparison of competing methods. This report contains such test cases. Geometric descriptions of seven, two-dimensional airfoils and suggested aerodynamic conditions for each are included. (Author).

Book Description
In the late seventies a need was perceived for standard comparison cases and experimental data to aid the comparison and validation of the theoretical methods then emerging for unsteady aerodynamics. A Working Group of the AGARD Structures and Materials panel chose a set of 2-D and 3-D configurations and for each configuration defined a set of test cases, including a priority subset, to be used for comparisons. These test cases were fully identified in ref. 1 and 2. The chosen configurations were known as the AGARD Aeroelastic Configurations and the chosen cases were denoted as Computational Test (CT) cases. Some of the CT cases were entirely theoretical while others were also the subject of unsteady measurements. The next step undertaken to aid the methods development was to produce an experimental data compendium (AGARD Report 702, ref. 3) which was conceived with the idea of bringing together the experimental data most important for the comparisons. The report was followed by an Addendum, ref. 4, which introduced two additional 3-D experiments. These reports established an admirable control base for providing experimental data and their value has been demonstrated by the repeated use of the test cases for the entire period since publication. The report has served as a model for the present new compendium of experimental data. It was decided that some of the data cases in the original Report 702 should be reproduced in this document in order to provide more complete coverage in this report with the additional bonus of making available the original data in electronic form to facilitate its continued use to validate calculations.
