    摘要: Techniques for deicing propellers for mobile platforms are disclosed. In one embodiment, a system is provided. The system may include a propeller comprising a propeller blade having a channel extending from an ingress aperture to an egress aperture along a longitudinal axis of the propeller blade. The system may further include a cowl comprising an air duct configured to direct heated air into the channel to deice the propeller blade. The cowl may be configured to selectively couple to the propeller and an electric motor and form a seal between the cowl and the electric motor to capture the heated air exuded by the electric motor. Additional systems and methods are also disclosed.

    摘要: Unmanned aircraft systems (UASs) and related techniques are provided to improve the operation of unmanned mobile sensor or survey platforms. A tether management system includes a logic device configured to communicate with a communication module and an orientation sensor coupled to a tethered unmanned aerial vehicle (UAV), wherein the communication module is configured to establish a communication link with a base station associated with the tethered UAV, the orientation sensor is configured to provide headings of the tethered UAV as it maneuvers within a survey area. The logic device is configured to determine an accumulated twist of a tether coupled between the base station and the tethered UAV and generate a tether damage warning notification based, at least in part, on the determined accumulated twist and a maximum allowable accumulated twist associated with the tether coupled between the base station and the tethered UAV.

    摘要: Unmanned aircraft systems (UASs) and related techniques are provided to improve the operation of unmanned mobile sensor or survey platforms. A flight altitude estimation system includes a logic device configured to communicate with a communication module and a flight barometer coupled to an unmanned aerial vehicle (UAV), wherein the communication module is configured to establish a communication link with a base station associated with the mobile platform, and the flight barometer is configured to provide flight pressures associated with the UAV as it maneuvers within a survey area. The logic device is configured to receive demark pressure data from a demark barometer coupled to the base station and determine a differential flight altitude estimation based, at least in part, on received flight pressure data and demark pressure data, a reference flight pressure and a reference demark pressure corresponding to a flight initiation location of the base station.

    摘要: Systems and methods directed to a visual safe indicator (VSI) for mechanical interruption of power to a fuze are provided. A VSI includes a circuit board including a pair of contact pads, a shaft configured to rotate about an axis, a visual indicator wheel coupled to rotate with the shaft, and a pair of spring contacts coupled to the visual indicator wheel, or any combination thereof. Rotation of the shaft rotates the visual indicator wheel to move the pair of spring contacts between connected and disconnected positions associated with powered-on and powered-off states of the VSI. The connected position engages the pair of spring contacts with the pair of contact pads to complete a circuit through the VSI. The disconnected position disengages the pair of spring contacts from the pair of contact pads to open the circuit. Additional systems and related methods are also provided.
