A fluid distribution system that uses a hovering distribution device and methods for using such a system are provided. In one example, the system may include a reel that provides a hose for the hovering distribution device. The hovering distribution device receives pressurized fluid from the hose, and includes at least one nozzle configured to distribute the pressurized fluid and provide lift for the hovering distribution device using the pressurized fluid. A control system may be configured to execute a fluid distribution plan by controlling at least one of a position and an orientation of the hovering distribution device in a three dimensional space using a direction of the nozzle.

A vehicle includes a main body and a gas generator producing a gas stream. At least one fore conduit and tail conduit are fluidly coupled to the generator. First and second fore ejectors are fluidly coupled to the at least one fore conduit. At least one tail ejector is fluidly coupled to the at least one tail conduit. The fore ejectors respectively include an outlet structure out of which gas from the at least one fore conduit flows. The at least one tail ejector includes an outlet structure out of which gas from the at least one tail conduit flows. First and second primary airfoil elements have leading edges respectively located directly downstream of the first and second fore ejectors. At least one secondary airfoil element has a leading edge located directly downstream of the outlet structure of the at least one tail ejector.

An airfoil is disclosed. The airfoil may comprise a leading edge, a body portion and a trailing edge formed from a high-modulus plating. The body portion of the airfoil may be formed from a material having a lower elastic modulus than the high-modulus plating. The high-modulus plating may improve the stiffness of the trailing edge, allowing for thinner trailing edges with improved fatigue life to be formed.

A propulsion system coupled to a vehicle. The system includes an ejector having an outlet structure out of which propulsive fluid flows at a predetermined adjustable velocity. A control surface having a leading edge is located directly downstream of the outlet structure such that propulsive fluid from the ejector flows over the control surface.

The present invention relates to a photographing device, including: a plurality of photographing units; a fixing unit, used for fixing the plurality of photographing units (9); and a power system, used for driving the fixing unit to rotate. The photographing device of the present invention is capable of realizing a 360? panorama photographing and realizing stabilization of the plurality of photographing units at the same time.

A local server includes a controller configured to select a processing function for processing offload, and receive, from a traffic filter, target data that originates from a local network; and a processing platform comprising one or more processors and configured to apply the processing function to the target data to obtain processed data; and wherein the controller is further configured to send the processed data to a remote server for remote processing.

Provided is a drone with a wind guide part, which is configured such that it can lift off or aviate using the flow of wind. The drone has a lift force by wind discharged towards the ground through a connecting duct and a wind guide part, so that the drone may lift off or aviate using the flow of the wind. Further, the drone may aviate without a propeller, thus preventing an accident due to the contact of the propeller, saving maintenance cost, and reducing weight and noise.
