An Unmanned Aerial Vehicle (UAV) controlled netting system is disclosed. The system includes a mesh netting and a battery powered UAV. The mesh netting includes a plurality of nettings arranged as interspersed layers in a mesh form. Each of the plurality of nettings has fire-resistant property. The battery powered UAV is present at an aerial location and the mesh netting is coupled to the battery powered UAV. The battery powered UAV is configured to maintain the mesh netting afloat and auto-adjust size of the mesh netting and porosity, based on one or more of size of embers in a fire and the quality of the fire.

Buoyancy modules filled with gases lighter than ambient air are described that are used to lift hoses and other lines off the surface of the ground. These buoyancy modules can support any line above the ground, the line delivering a fluid or energy from a source to a target.

A flying object includes: a fuselage; a wing that extends laterally from the fuselage and can generate lift during cruising; and a thrust generation unit that can generate thrust. The wing includes a fixed wing portion fixed to the fuselage, and a deployable wing portion deployable forward in a front-rear direction from the fixed wing portion, and a plane area of the wing in a deployed state in which the deployable wing portion is deployed forward in the front-rear direction is larger than a plane area of the wing in a superposed state in which the deployable wing portion is superposed on the fixed wing portion.

A system and method directed to an inflatable aerial beam transported by aerial vehicles for dispensing, among others, power and fluids using the inflatable aerial beam that may be mounted between two or more aerial vehicles. The beam, may become rigid when inflated or flexible when deflated. The beams may be coupled to one or more aerial vehicles via a pivotable joint or a flexible juncture to maintain flexibility of movement of the aerial beams. The beams may include a fluid dispenser that distributes fluid to spray nozzles to dispense fluids from the inflatable beam. The fluid, chemicals, and/or power may be obtained from a remote fixed or mobile source, one or more aerial vehicles, and other types of aerial vehicles. The aerial vehicles may be controlled remotely from a fixed location or from a movable remote-control source and may include sensors for navigation and for controlling the dispensing of the fluid or power.
