    Abstract: A system for inspecting a wire segment includes an inspection apparatus and a visual imaging device. The apparatus includes an array of mirrors positioned about a centerline of the apparatus, wherein each mirror in the array is oriented such that a reflection of a first inspection zone of the wire segment in the array of mirrors forms a circumferential view of the first inspection zone of the wire segment, and the reflection from each mirror is within a field of view from a single vantage point. The visual imaging device is positioned at the single vantage point and oriented towards the wire segment such that the reflection from each mirror of the array of mirrors is within a field of view of the visual imaging device, the visual imaging device configured to capture at least one image of the reflection of the wire segment from the array of mirrors.

    Abstract: Systems and methods for transferring electric power to an aircraft during flight. Power transfer to the receiver aircraft is effected by means of a donor aircraft using a wired electrical connection. The method for transferring electric power includes: establishing an electrical connection between a receiver aircraft and a donor aircraft during flight; and transferring electric power from the donor aircraft to the receiver aircraft via the electrical connection. In one embodiment, electric power is transferred by way of a power cable deployed by the donor aircraft, a drogue attached to a trailing end of the power cable, and a probe mounted to the fuselage of the receiver aircraft, The probe and drogue are configured to form an electrical connection when fully engaged.

    Abstract: Methods and systems according to one or more examples are provided for avoiding foreign object strikes on rotorcraft vehicles. In one example, a vehicle comprises a rotor comprising a rotor blade, a first sensor configured to provide first sensor information associated with an object proximate the vehicle, and a second sensor configured to provide second sensor information associated with the rotor. The vehicle further comprises a processor coupled to the first sensor and the second sensor configured to selectively control the rotor to minimize damage to the vehicle by the object based on the first and second sensor information.

    Abstract: Methods and systems according to one or more examples are provided for controlling a multi-rotor vehicle. In one example, a multi-rotor vehicle comprises an airframe and a plurality of rotors coupled to the airframe. The multi-rotor vehicle further comprises a controller, coupled to the airframe, configured to determine a rotational speed of each of the plurality of rotors, and adjust the rotational speed of each of the plurality of rotors such that the rotors do not dwell within a no-dwell zone comprising rotational speeds associated with one or more frequency aspects of the airframe.

    Abstract: An animal-entry protection apparatus and related methods for protecting protected areas from animal entry are described. The animal-entry protection apparatus includes an eye-safe laser and a computing device. The animal-entry protection apparatus determines whether an animal has entered into a protected area. After determining that the animal has entered into the protected area, the animal-entry protection apparatus determines a location of the animal within the protected area and activates the eye-safe laser to emit a pulsed laser beam toward the location of the animal. The pulsed laser beam includes laser pulses having a laser-pulse rate that is between a first laser-pulse rate associated with a flicker-fusion frequency of a human eye and a second laser-pulse rate associated with a flicker-fusion frequency of an animal eye.
