Description
Summary:An increased number of requirements for supersonic wind tunnel tests at high angles of attack (AoA) opened the problem of the validation of a high-AoA wind tunnel setup in the Experimental Aerodynamics Laboratory of VTI (Military Technical Institute) in Belgrade. Tests of the supersonic-hypersonic HB-2 models were performed at Mach numbers 1.5 to 4 at AoA up to +30°. A new bent sting was used as the model support, shifting the AoA range of the wind tunnel model support. Obtained data were correlated with results of previous tests performed in the same wind tunnel in the lower-angle-of-attack range and with available test results from other wind tunnel facilities. The results are found to be useful as supersonic test cases for both experimental and numerical researchers
