Abstract: Embodiments disclosed include a rotary-wing drone that includes a drone body and linking arms, such that a propulsion unit is located at the distal ends of the linking arms. The rotary-wing drone may also include a stiff battery pack with at least one fixation means and a guiding profile. The drone body may also include a platform with at least one guiding rail configured to cooperate and receive the complementary guiding profile of the battery pack and at least one fixation means complementary to the fixation means of the battery pack so that the battery pack attaches onto and stiffens the drone body.

Abstract: Disclosed are embodiments of a rotary-wing drone that includes a drone body, linking arms that extend from the drone body with a propulsion unit located on a distal end of the linking arms, and at least two drone supports extending from the drone body. The drone supports may include a lifting means so that the drone supports are able to be lifted when the drone flies, where the drone supports come into alignment with the linking arms. The drone supports may form the leading edge of the rear linking arms and/or the trailing edge of the front linking arms of the drone.

Abstract: Disclosed are embodiments of a rotary-wing drone that includes a drone body with two front linking arms and two rear linking arms extending from the drone body with a propulsion unit located on a distal end of the linking arms. The points of fixation of the front linking arms and the points of fixation of the rear linking arms are located at different respective heights with respect to the horizontal median plane of the drone body. The two front linking arms of the drone may form a first angle of inclination with respect to the horizontal median plane of the drone body and the two rear linking arms may form a second angle of inclination. Additionally, the linking arms of the drone may further be adapted to be folded over along the drone body.

Abstract: The invention relates to a rotary-wing drone (10) comprising a drone body (30) that comprises an electronic circuit board controlling the flight of the drone, four link arms (36) comprising a propulsion unit (38) at their ends, two propulsion units each having a propeller (12) that rotates in the clockwise direction and two propulsion units each having a propeller that rotates in the anticlockwise direction, the propulsion units that have propellers that rotate in the same direction being positioned on the same diagonal line. The drone comprises a propulsion support (32) comprising the link arms (36) and a central hub (34), two pairs of symmetrical link arms each extending on either side of the central hub, the central hub (34) being capable of being coupled to the drone body (30), and the propulsion support (32) having at least one torsional bending direction extending in the horizontal plane.

Abstract: The invention relates to a rotary-wing drone (10) comprising a drone body comprising an electronic board controlling the piloting of the drone, wireless communication means and a plurality of connection arms, said wireless communication means being connected to a communication antenna (46), a plurality of propulsion units (36) mounted at the end of respective connection arms (34), and at least one drone body support (38) adapted to maintain the drone body remote from the ground. The drone body support (38) comprises an antenna housing (44) provided with means for holding the communication antenna.

Abstract: The drone body (10) comprises a frame (12), integral with arms (14) for connection to propulsion units (16), an electronic board (24) carrying components as well as accelerometer, inertial and altimeter sensors, a support for this board, and an elastic interface (26) between the frame and the board support, to filter and absorb the mechanical vibrations. The board support is a panel (22) made of an electrically conductive metal material. The panel carries on a back side thermally conductive areas at places located opposite heat-sink electronic components mounted on the board on the back side. The panel is moreover electrically connected to a ground potential of the electronic board, so as to form an electromagnetic shielding screen. It is further mechanically connected to the frame with uncoupling by the elastic interface (26) interposed between the panel and the frame.

Abstract: A remote control unit carries control keys and possesses in its back face a battery housing with central and peripheral power supply contacts, and also with signal transmission contacts. An active support carries a portion in relief suitable for penetrating into the housing of the unit to take the place of the power supply battery. Two power supply terminals are connected to a power supply line and arranged so as to bear against the respective power supply contacts of the unit when the portion in relief is inserted and locked in the housing of the unit, with the same applying for signal transmission terminals that are arranged on the portion in relief in positions that correspond to the transmission contacts of the unit.

Abstract: The support (300) is intended to be fixed in a housing provided in the drone, through a mechanical interface (310) made of a material absorbing the mechanical vibrations. The mechanical interface, annular in shape, is intended to be attached to a corresponding annular shoulder provided in the housing. A fastening part (301) for fixing the support in the housing carries the mechanical interface (310), with at least one connection leg (302) supporting the navigation electronic card (320) and mounted free at one end on the fastening part. A battery (400) for the power supply of the drone is further accommodated in the support. The navigation electronic card may notably include a navigation sensor (321) such as an accelerometer, placed on the card in such a manner to be positioned at the barycenter of the drone.
