Abstract : During this year, we demonstrated the ability not only to cover the surface of a simulated aircraft fuselage with a thin layer of plasma at one atmosphere in both atmospheric air and helium, but we also demonstrated that this plasma layer would not blow away under the impact of a jet of air from the laboratory service air supply. These results strongly suggest that the one atmosphere plasma layer might be useful for boundary layer control and drag reduction on aircraft. This contract has also resulted in 3 issued patents (to which the U.S. Government has a royalty-free license); two patent disclosures; two poster paper presentations at conferences, two archival journal pulications, and two invited seminar presentations, at the Kirtland AFB and at the NASA-Langley Research Center. It is expected that this work will continue in the wind tunnels at Langley.
