Session 7P - Plasma Applications and Plasma Technology.
POSTER session, Thursday morning, November 14
Exhibit Hall - Concourse Level, Adam's Mark
The results of low-speed wind tunnel testing at the NASA Langley Research Center of a flat panel substantially covered by a thin layer of one atmosphere uniform glow discharge plasma (OAUGDP)^1 will be reported. The orientation of the electrode strips and the resulting lineation of the OAUGDP with respect to the airflow was found to have a significant effect on the amount of measured drag. When the plasma panel is oriented so that the electrode strips are parallel to the airflow, the measured drag increases. Utilizing standard circuit board technology, a multi-strip OAUGDP layer was created on a rectangular surface (30 \times 34 cm). One side of the panel was a series of connected strip electrodes and the other side a single sheet electrode. The panel was operated at a RMS voltage of 1.0-4.0 kV, RF frequency of 1.0-4.0 kHz, in a parallel and perpendicular airflow.
