  • Patent number: 10446373
    Abstract: In an embodiment of the invention there is a cyclotronic actuator utilizing a high-voltage plasma driver connected to a first electrode. A second electrode is grounded and the two are isolated from each other by a dielectric plate. A magnet is positioned beneath the dielectric plate such that a coaxial dielectric barrier discharge plasma is formed outwardly between the first electrode across the dielectric plate. The magnet positioned beneath the dielectric plate introduces a magnetic field transverse to the plasma current path, such that the plasma discharge discharges radially and the local magnetic field is oriented vertically in a direction perpendicular to the dielectric plate to create a Lorentz Force, which forces the plasma discharge to move radially outwardly in a curved radial streamer mode pattern.

  • Patent number: 10332724
    Abstract: In an embodiment of the invention there is a cyclotronic actuator. The actuator is defined by having a high-voltage plasma driver connected to a first electrode. The first electrode is surrounded by a dielectric material. A second electrode is grounded and placed away from the first electrode, such that a plasma arc is formed between the pair of electrodes when the high-voltage plasma driver is activated. A ring magnet surrounding the second electrode is configured to introduce a magnetic field locally to the plasma arc. The plasma arc will then discharge in a radial direction. The magnet creates a local magnetic field oriented vertically in a direction parallel to the axisymmetric orientation of the first and second electrodes to create a Lorentz Force. The force causes the plasma arc to move in a tangential direction and causes the plasma arc to discharge out in a circular pattern.

  • Publication number: 20130345910
    Abstract: Methods and apparatus for predicting airfoil stall for an aircraft having a control surface. Measurements of forces or moments acting upon an integrated span of the control surface are sensed over a period of time to provided unsteady data. The unsteady data is filtered to remove structural frequencies and input to at least one stall warning detection function, and an output is received. Each of the stall warning detection functions identifies an angle-of-attack that is approximately within a predetermined number of degrees of stall when the received output reaches a threshold. The received output is compared to the threshold to determine whether an angle-of-attack exists that is near stall.
