An aerially controlled sludge level detection system is for determining a sludge level in a wastewater reservoir. The system may have a drone and a sludge level detection tool suspended from the drone. The drone may be operable to lower the sludge level detection tool into the wastewater reservoir and raise the sludge level detection tool out of the wastewater reservoir. The sludge level detection tool may have a longitudinally extending gauge. At least a portion of the gauge at a distal end may be hollow to allow a volume of a fluid and a volume of the sludge from within the wastewater reservoir to enter the gauge when lowered into the wastewater reservoir. The sludge level detection tool may also have an analyzer connected to the gauge for analyzing the volume of the fluid and the volume of the sludge within the gauge.

The present disclosure belongs to the technical field of unmanned aerial vehicles, and specifically relates to an airdrop device used with an unmanned aerial vehicle. The airdrop device includes a clamping jaw bearing block, a control panel, a power supply, a power source, and a photosensitive sensor. The clamping jaw bearing block is used to be detachably connected with an unmanned aerial vehicle; the control panel, the power supply, the power source, and the photosensitive sensor are all mounted on the clamping jaw bearing block; and the output end of the power source is provided with an engine arm used to hang a material bag. The power supply, the power source, and the photosensitive sensor are all connected with the control panel; and the control panel receives a light signal detected by the photosensitive sensor and controls the power source to act. The airdrop device used with the unmanned aerial vehicle of the present disclosure has a simple and reasonable structure. The clamping claw bearing block is detachably connected to the unmanned aerial vehicle, and the material bag is hung on the engine arm. When materials need to be thrown in air, light below the fuselage of the unmanned aerial vehicle is turned on, and the control panel receives the light signal detected by the photosensitive sensor and controls the power source to act so that the engine arm rotates to detach the material bag.

An unmanned aerial vehicle (UAV) can deliver a package to a delivery destination. Packages delivered by a UAV may be lowered towards the ground while the UAV continues to fly rather than the UAV landing on the ground and releasing the package. Packages may sway during lowering as a result of wind or movement of the UAV. By modulating a rate of descent of a package, a package sway may mitigated. The lowering mechanism includes wrapping a tether in various directions around the package such that the package rotates in a first and second direction as the package descends. Additionally, a rip-strip lowering mechanism that separates under tension to lower the package and a rappel mechanism that slides the package down a tether may be used. Accordingly, the tether can control a descent of the package assembly.

A human and/or non-human cargo attachment device for a rotorcraft, comprising: a mounting interface with a mounting base carrier 11d that is removably attachable to an associated attachment for attachment to a rotorcraft rope or cable; a connecting member that is spaced apart from the mounting base carrier; and a plurality of lateral attachments which are connected to the mounting base carrier and the connecting member; wherein each lateral attachment of the plurality of lateral attachments forms a main lashing point for attachment of human external cargo and comprises an associated inner web that is connected to the mounting base carrier and the connecting member; and wherein the associated inner webs of the plurality of lateral attachments are spaced apart from each other in peripheral direction of the mounting base carrier and form a tube-shaped inner region.

A drone delivery system hub and method for sending for take-off and receiving for landing unmanned aerial vehicles (UAVs). The drone delivery system hub includes a center shaft frame, a parcel-conveying system supported by the center shaft frame, structural arms coupled to and extending outward from the center shaft frame in a spoke-like configuration, drone-conveying systems each supported by one of the structural arms, and a linking conveyor span. The drone-conveying system conveys the UAVs along a length of a correspond one of the structural arms toward and away from the center shaft frame. The linking conveyor span selectably rotates to different orientations between different pairs of the structural arms, selectively conveying a UAV thereon between any two of the structural arms. The linking conveyor span is located above the parcel-conveying system such for the UAV thereon to deposit and retrieve parcels from the parcel-conveying system.
