Non-intrusive measurement technology validated

Nickolas Galyen, an engineer in Aerospace Testing Alliance’s Integrated Test and Evaluation department, aligns a calibration target during a series of tests to validate the use of stereo particle image velocimetry (PIV) in the 4-foot transonic wind tunnel at Arnold Engineering Development Center. Images of the precisely machined target are used to spatially calibrate particle images to measure three-dimensional velocity airflow fields.
