T-38 Wind-Tunnel Data Quality Assurance Based on Testing of a Standard Model

A 3D analysis of geometrical factors and their influence on air flow around a satellite dish

“…The real-technical system satellite antenna was examined at the Aviation Technical Institute in Belgrade (VTI) [8], the fact of the wind opposing. Antennas were made of perforated metal, calotte diameter parabolic 3m [9].…”

Testing of a standard model in the VTI's large-subsonic wind-tunnel facility to establish users' confidence

“…VTI has recognized the necessity of the standard model testing as an aid for establishing statistical control on test data by providing a database of standard test results variability and has established a procedure for windtunnel data quality assurance, [3,4].…”

“…Mach 0.4 data in the wind-axes system at the aerodynamically same angles of attack from modelupright and model-inverted runs were compared to check test section symmetry. Data in a non-rotated wind-axes system from the model-upright run are to be compared with data from the model-inverted run to check the model symmetry, [3,4].…”

“…The accuracy requirements for standard models wind-tunnel data are specified concerning three different categories, [3,4].…”

“…A new-implemented standard testing procedure, an acquired database and an experience in the VTI's trisonic test facility were an excellent background in the process of verification of the other VTI's facilities, [3,4].…”
