    Abstract: Systems and methods for enabling charged (ionized) air mass measurement for reliable air data computation onboard an aircraft. Ionic charge sensing may be used to derive air data having improved reliability. The systems and methods for ionic charge sensing employ an emitter electrode and two or more collector electrodes, which electrodes are disposed in proximity to the exterior skin of the aircraft and exposed to ambient air. The emitter electrode is positioned forward of the collector electrodes. The system further includes a solid-state ionic air data module that converts currents from the collector electrodes into air data parameter values. More specifically, the ionic air data module is configured to sense currents induced in the collector electrodes in response to corona discharge produced by the high-voltage emitter electrode.

    Abstract: Systems include a test object that comprises a surface having a non-planar topographical feature, and an electrode comprising a non-linear segment that is proximate to the non-planar topographical feature of the surface of the test object. The electrode is positioned proximate to but not in contact with the surface of the test object such that the perpendicular distances between the electrode and the surface of the test object are uniform across the electrode. The electrode is further configured to (i) be translated across the surface of the test object while maintaining the perpendicular distances between the electrode and the surface of the test object, and (ii) impart a layer of charge across the surface of the test object when the test object is translated across the surface.

    Abstract: An example method for plasma cleaning a container includes generating plasma flowing within the container, applying a magnet to an exterior surface of the container causing the plasma within the container to be attracted to the magnet, and moving the magnet in a motion over the exterior surface to control movement of the plasma within the container and to clean one or more areas of the container with the plasma according to the motion. An example system for plasma cleaning a container includes a power source, a gas inlet on the container for dispersing a gas within the container, and based on current flowing, the gas converts to plasma. The system also includes a robotic manipulator having an end effector coupled to a magnet to move the magnet in a motion over an exterior surface of the container causing the plasma within the container to be attracted to the magnet.

    Abstract: Systems and methods for electromagnetically controlling the muzzle velocity of a conventional gun using a coil gun on a barrel extension. This method can also provide an electromagnetically induced increase to muzzle velocity beyond that capable by conventional explosives. With higher muzzle velocity, the weapons will have longer range, higher penetrating power and stand-off distances. A section of coil gun can also be used to center the projectile in the barrel to control the exit trajectory. Using a coil gun to control muzzle velocity and center the projectile can be a retrofit to existing weapons that would greatly increase their down-range accuracy.

    Abstract: A scramjet includes a converging inlet, a combustor configured to introduce a fuel stream into an air stream in a combustion chamber and to combust the fuel air mixture stream to create an exhaust stream, and a diverging exit nozzle configured to accelerate the exhaust stream. The combustor includes a fuel injection system including at least one arcjet. A method of creating thrust for an aircraft includes compressing a supersonic incoming air stream in a converging inlet, injecting a fuel stream into the air stream in a combustion chamber to create a fuel air mixture stream, igniting the fuel air mixture stream to create an exhaust stream, and exhausting the exhaust stream from a diverging exit nozzle. The injecting the fuel stream into the air stream includes injecting the fuel stream at a fuel speed sufficient to create shear between the fuel stream and the air stream.
