A piece of rotary equipment for a drone, the rotary equipment having a rotary assembly including at least one blade. The rotary assembly includes at least one furrow that extends in a skin from a first end to a second end, the at least one furrow being at least arranged over the blade, the at least one furrow presenting at least one change of direction on the blade, the rotary assembly including at least one deicer having an electrically conductive track that extends in the at least one furrow, the electrically conductive track extending from a first terminal to a second terminal, the first terminal being present at the first end and the second terminal being present at the second end, the deicer including a protective layer covering the electrically conductive track.

Method of fabricating rotary equipment for a rotary wing, provided with a deicer, said rotary equipment, and a drone provided with said rotary equipment

An industrial activity drone comprising an aerial vehicle having at least one rotor, an activity system, and a fastener device for fastening the activity system to the aerial vehicle. The activity system includes a structure, a computer, a work camera that is stationary relative to the aerial vehicle and that provides a view of a work zone, a distribution device having a plurality of compartments, and a turning motor enabling the distribution device to turn relative to the aerial vehicle. The industrial activity drone performs hovering flight so that the work camera faces a work zone and the distribution device is turned so that the compartment that is to be used faces the work zone, thereby performing one or more tasks.

Drone for industrial activities

The present invention relates to a rotorcraft rotor () having a plurality of blades () movably mounted on a hub () via blade roots () that are respectively associated therewith. The rotor () is fitted with an information capture appliance having at least one measurement assembly (E) comprising a flexible bar () interposed in engagement at its respective ends between the hub () and a blade root () that is allocated thereto. A strain gauge () formed of a SAW transducer is implanted on the bar () and generates information relative to the bending of the bar () following tilting orientations of the blade root () in flapping (B) and/or in lag (T).
