AVT387: Experimental Characterization of Flow Conditions in the Transonic Wind Tunnel Göttingen with Perforated Test-Section

Kurzfassung

This paper presents the results of the experimental investigation of the Transonic Wind Tunnel Göttingen with perforated test section that were performed in the scope of the NATO STO AVT-387. The focus of the investigation is the detailed characterization of the flow topology inside the perforated test section and the surrounding plenum. The scope of the study encompasses boundary layer profiles, pressure and temperature measurements in the center of the test section and pressure measurements in the surrounding plenum. Besides measurements at the reference condition, small variations of the static pressure in the plenum and the total pressure are also covered.
