    Abstract: Airflow-dependent deployable fences for aircraft wings are described. An example apparatus includes a fence coupled to a wing of an aircraft. The fence is movable relative to the wing between a stowed position in which a panel of the fence extends along a skin of the wing, and a deployed position in which the panel extends at an upward angle away from the skin. The panel is configured to impede a spanwise airflow along the wing when the fence is in the deployed position. The fence is configured to move from the stowed position to the deployed position in response to an aerodynamic force exerted on a deployment vane of the fence.

    Abstract: Drag reduction systems and methods for an aircraft include a first vortex generator position on a portion of the aircraft, and a second vortex generator positioned on the portion of the aircraft. The first vortex generator is associated with the second vortex generator. The first vortex generator is asymmetrical to the second vortex generator in relation to a coupling axis in order to offset the longitudinal contribution of the vortex generator to vehicle cross-sectional area.

    Abstract: Implementations provide an aircraft synthetic vision system (“SVS”) giving passengers an exterior view. Omitting windows reduces costs, lowers weight, and simplifies hypersonic aircraft design and construction. Unlike contemporary SVSs, no lag exists between the exterior view and actual aircraft motion. Passengers experience no airsickness associated with a visual and vestibular system feedback mismatch. Lag is eliminated by predicting aircraft interior motion based on sensor feedback, and (b) displaying video camera images transformed to match the predicted aircraft orientation when the images get through the display system latency. Implementations predict aircraft orientation and pre-transform—through the use of dead reckoning to adjust a video signal based on sensed aircraft dynamics and an aircraft electronic model—an image captured from a video camera to match that orientation at the image display time. This approach is robust, cheaper, and more effective than conventional SVS at providing an airsickness-free view of the aircraft exterior.

    Abstract: In an example, a method of supplying fuel to a fuel tank of a vehicle includes supplying, via a fuel line, fuel to a fuel tank of a vehicle at an initial rate of fuel flow. The act of supplying the fuel causes an electrostatic charge to accumulate on a surface of the fuel in the fuel tank. The method also includes determining a level of ionization of an air medium in the fuel tank, and determining an increased rate of fuel flow based on a difference between the determined level of ionization and a baseline level of ionization. The electrostatic charge accumulated on the surface of the fuel dissipates at an increased rate when the determined level of ionization of the air medium is higher than the baseline level of ionization. The method further includes supplying the fuel to the fuel tank at the increased rate of fuel flow.

    Abstract: An example method includes determining, by a flight planning system, a perceived noise at a surface location based on acoustic noise emitted by an aerial vehicle at an aerial location. The aerial location corresponds to a waypoint along a proposed trajectory. Further, determining the perceived noise includes estimating propagation of the acoustic noise from the aerial location to the surface location based on environmental features of the environment or weather data. The flight planning method also includes determining, by the flight planning system using a noise-abatement function, a noise-abatement value of the proposed trajectory for the aerial vehicle based on the perceived noise at the surface location. In addition, the flight planning method includes determining, by the flight planning system, a flight plan for the aerial vehicle based on the noise-abatement value of the proposed trajectory, and outputting the flight plan for use in navigating the aerial vehicle.

    Abstract: A radioisotope power source is disclosed. In one embodiment, the power source includes a dielectric liquid held within a vessel, a radioisotope material dissolved as an ionic salt within the dielectric liquid thereby forming an ionic salt solution, and a thermal-to-electric power conversion system configured to receive thermal heat generated from the decay of the radioisotope material and to generate electrical power.
