Provided is an airbag device for a flying object sufficiently having a performance of protecting a battery.

An airbag device 1 is an airbag device for a flying object including an upper cover member 19 and a lower cover member 20 as a housing, and a battery 24 provided inside the housing and includes an expandable member 2 which is provided inside the housing of the flying object 10 and is expandable inside the housing, a gas generator 3 which is connected to the expandable member 2 and receives a predetermined amount of current to make gas flow into the expandable member 2, and a current supply section which supplies current to the gas generator 3 according to collision of the flying object 10.

An unmanned aerial vehicle according to the present invention includes: a main body; an arm that extends from the main body to support a rotor; a first electrical conductor which is supported by the arm and to which a voltage is applied; a second electrical conductor which is supported by the arm and spaced apart from the first electrical conductor and to which a voltage lower than the voltage applied to the first electrical conductor is applied; and a controller configured to control electrical supply to the first and second electrical conductors.

A projectile-launched aircraft system includes a projectile launcher including a triggering mechanism, a rotary-wing, hover-capable aircraft including a rotor assembly that includes at least one rotor blade, wherein the rotor blade includes a stowed configuration and a deployed configuration that is circumferentially spaced from the stowed configuration about a pivot axis, wherein, upon actuation of the triggering mechanism, the projectile launcher is configured to launch the aircraft along a flightpath.

A drone with railway driving capabilities has a drone body and at propeller arms. Each propeller arm has a propeller assembly having a propeller driven by a motor assembly. The propeller assembly of at least one propeller arm has a rotatably mounted propeller guard placed coaxially with the propeller. The propeller guard is shaped as a train wheel and is driven by the motor assembly. The propeller arm has an actuated joint for providing the propeller assembly with at least one rotation degree of freedom so that the propeller can be rotated between a flight mode and a driving mode and back. The flight mode involves a more horizontal orientation of the propeller assembly for providing an upwardly directed thrust force to the drone, in operational use, and the driving mode involves a more vertical orientation of the propeller assembly for allowing the respective propeller guard to drive on the railway track.

Detectors detect a user's touch operation to an airframe, and a motor control unit controls rotations of motors, based on the user's touch operation detected by the detectors. The motor control unit is configured to have a hovering function of making the airframe automatically perform a stationary flight at a hovering position. The motor control unit keeps the setting of the hovering function off during a period while the detectors are detecting a user's touch operation, and when the detectors stop detecting a user's touch operation, the motor control unit sets the hovering function on.

A system for video imaging and photographing using an autonomous aerial platform. The system may be a quad rotor system using electrically powered propellers. The aerial platform may be commanded by the user to follow an object of interest. The aerial platform may have multiple configurations for its thrust units such that they are clear of the field of view of the imaging device in a first configuration, such that they protect the imaging device during landing in a second configuration, and that allows for efficient storage in a stowed configuration.

A small consumer drone is used to measure RF signals, such as within the vicinity of a cell tower. The drone's frame is fitted with an antenna support device which can be in the form of two intersecting arches of dielectric material. An antenna of selected specification is secured to the antenna support. In this way, the antenna support not only provides a secure mounting for the antenna, but also provides protection from objects above the drone.

A propeller guard 2 includes: a propeller guard body 10 configured to surround a propeller 30 of a flight vehicle 20; and a rotating member 40 provided on a side surface of the propeller guard body 10, in which the rotating member 40 is able to rotate around at least a horizontal base axis in a case where the rotating member 40 is in contact with a vertical plane located outside the propeller guard body 10.
