The TDT is a continuous-\ufb02ow, closed circuit, slotted-test-section wind tunnel with a 16by 16-foot test section with cropped corners. The tunnel was originally built as the 19-ft Pressure Tunnel in 1938, but it was converted to the current transonic tunnel in the 1950s, with capabilities to use either air or heavy gas at pressures from atmosphere down to near vacuum. In this study, experimental data acquired in the empty tunnel using R-134a as the test medium was used to calibrate the computational data. Experimental data from a recent TDT test of a full-span \ufb01ghter con\ufb01guration in air was then selected for comparison with the numerical data. During this test, the con\ufb01guration experienced a \ufb02utter event in the transonic \ufb02ow regime. Numerically, the \ufb02utter event is simulated both inside the CFD model of the TDT and in a classical free-air model. The preliminary results show that the wind-tunnel walls do affect the response of the tested vehicle but do not affect overall \ufb02utter prediction.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/08\/IFASD-2017-044.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Pawel Chwalowski, Walter A.
