In this article, test results of AGARD-B calibration model, performed at the beginning of 2006 in the T-38 trisonic wind tunnel of the Military Technical Institute, are presented. The test results are compared with the results of the tests of the same model performed in 1981 in the IAR (NAE) 5ft trisonic wind tunnel (Canada), and with the results of the test performed in 1986 during the commissioning of the T-38 wind tunnel. Analysis of the test results showed a good agreement with the results obtained in the distinguished IAR (NAE) 5ft wind tunnel, confirming a high quality of air stream in the test section of the T-38, good condition of instrumentation and the correctness of the data reduction algorithm.

Key words: experimental aerodynamics, calibration model, trisonic wind tunnel.
