A navigation system for an unmanned aerial vehicle (UAV). The navigation system includes a dedicated short range communication (DSRC) module onboard the UAV configured to communicate with DSRC modules of land-based vehicles for tracking travel paths of the land-based vehicles and deriving location of roadways based on the travel paths. A flight control module of the UAV is configured to navigate the UAV to follow roadways identified based on the tracked travel paths of the land-based vehicles.

Embodiments of the present disclosure provides a method and a system for managing an UAV in a smart city based on IoT. The method includes obtaining requirement information of a user by a general platform of the management platform from the user platform through the service platform, and assigning the requirement information to a corresponding management sub-platform; determining different time domains and different airspaces of at least two UAVs performing missions by the management sub-platform based on the requirement information, wherein the different time domains may have an overlapping interval, and the different airspaces may have an overlapping interval; and controlling the at least two UAVs to perform the different missions in the different time domains and the different airspaces by the management platform, and collecting mission data corresponding to different missions.

An aircraft has a boom, a propulsion assembly coupled to a first end of the boom, and a first wing coupled to a second end of the boom. The propulsion assembly is coupled to the boom by a rotating joint. A second wing is optionally coupled to the rotating joint. The first wing is coupled to the boom by a rotating joint. The first wing is coupled to the rotating joint by a hinge. A vehicle with roll, pitch, and yaw maneuverability able to mirror the aircraft movements may be coupled to the second end of the boom. The vehicle body may be picked up with a vehicle chassis disconnected from the vehicle body. The boom houses an energy source to power the propulsion assembly. A rudder is coupled to the second end of the boom. A paddle is disposed between the propulsion assembly and the boom.

The embodiments herein relate to encryption and decryption of media data transmitted between an Unmanned Aerial Vehicle (UAV) and a ground controlling base, when recording and playing back the media data by combining symmetric and asymmetric cryptography.

Aspects of the present invention relate to a nacelle (14) for a wind turbine generator (10), and a method for transferring components into and out of a wind turbine generator (10). The nacelle (14) comprises a housing (26) surrounding an internal volume (24) of the nacelle (14). The housing (26) has a maintenance opening (50). The nacelle comprises a carriage (54) configured to hold a component (48), the carriage (54) being movable between a first position and a second position to transfer the component (48) through the maintenance opening (50). When the carriage (54) is in the first position, the component (48) is held within the internal volume (24). When the carriage (54) is in the second position, the component (48) is held such that at least a portion of the component (48) is outside the housing (26).
