Provided is an unmanned aerial vehicle configured to be able to discharge a liquid, comprising: a container of the liquid; a discharging unit configured to discharge the liquid; and a coupling unit configured to couple the container and the discharging unit together, wherein the coupling unit includes a buffering unit configured to buffer stress generated in the coupling unit. The container may be an aerosol container. The coupling unit may include a rigid unit coupled to the buffering unit and configured to have rigidity higher than the buffering unit.

Unmanned aerial vehicle (UAV) including an inner frame, an inner flight propulsion system mounted on the inner frame, an outer frame, a gimbal system comprising at least two rotational couplings coupling the inner propulsion system to the outer frame, a control system, a power source, and an outer frame actuation system configured to actively orient the outer frame with respect to the inner frame.

The present invention relates to a protective foldable cage (100) adapted to flying drones. It comprises several ribs linked at their extremities by a ring and comprising on their length several connexion points allowing strings to join each of the adjacent ribs. The length of the string corresponds to the maximal angular shift between the first and the last ribs. The protective cage further comprises easily removable locking means adapted to maintain the ribs at predetermined relative angular position once deployed. The resent invention further relates to a system comprising such a protective cage and a drone support, as well as a method of protection of flying drones.

A remote health care apparatus is disclosed that incorporates a drone device and a health kit. The drone device includes one or more communication devices, and the drone device is capable of two-way auditory and visual communication. The health kit is capable of being transported by the drone device and can be detached from the drone device. In one embodiment, the health kit contains one or more medical devices selected from the group consisting of biometric measuring devices, specimen collection devices and lab testing tools.

A vertical take-off and landing (“VTOL”) unmanned aerial vehicle (“UAV”) system and a method of controlling the same, wherein such method controls the stability and maneuverability of the VTOL UAV by manipulating the speeds of the propellers at each rotor. The VTOL UAV includes a body with three extending arms, wherein each of such arms is aligned and fixed at a certain angle from a central axis passing through the body. Each extending arm is equipped with a rotor with propellers. The rotors are sufficient to control the yaw of the UAV, and there is no need for coaxial rotors or an extra servo-motor in order to control the yaw of the UAV, thus reducing the cost and the weight of the UAV.

Provided is a flight vehicle and in particular a flight vehicle in which a main module equipped with a device capable of carrying cargo, photographing, etc. may freely switch directions during flight while applying a posture independent of a thrust module because the thrust module is configured to freely perform roll and pitch motions with respect to the main module.

An aircraft (100) includes a body (10) and an outer frame (1) rotatably coupled to the body (10). The body (10) includes a plurality of rotary blades (15a-15d) and a driver (14a-14d) configured to rotate the plurality of rotary blades (15a-15d). The outer frame (1) includes a rotary frame (1a-1c) rotatable about a rotation axis intersecting the direction of gravity, and a center of gravity of the plurality of rotary blades (15a-15d) and the driver (14a-14d) is located lower than the rotation axis in the direction of gravity.

A method is provided. An airship is maneuvered to a desired location and oriented with the thruster such that ambient wind is traveling in a direction that is substantially parallel to the longitudinal axis of the fuselage. The airflow from the ambient wind is straightened with the flow straightener to generate a substantially laminar flow. The turbine is engaged with the airflow generated by the ambient wind to generate electricity, and the electricity generated by the turbine is rectified with the rectifier and stored in the storage array.

Methods and apparatus for performing repair operations using an unmanned aerial vehicle (UAV). The methods are enabled by equipping the UAV with tools for rapidly repairing a large structure or object (e.g., an aircraft or a wind turbine blade) that is not easily accessible to maintenance personnel. A plurality of tools are available for robotic selection and placement at the repair site. The tools are designed to perform respective repair operations in sequence in accordance with a specified repair plan, which plan may take into account the results of a previously performed UAV-enabled inspection.
