The present disclosure provides aerostat display, which utilizes the aerial display by exploiting the visual residue of pointolites rotating around the outer surface of the aerostat on human eyes.

A flying object with a landing gear module serving as a floating weight that can be used simultaneously with an airship and an aerial mooring type aerostat, and more particularly, a flying object capable of simultaneously allowing a landing gear to serve as a floating weight, thereby stably simplifying a mooring process of the flying object and manufacturing the flying object at low cost.

Systems and methods are disclosed for package delivery using unmanned aerial vehicles. Example methods may include positioning a first component at a first elevation, and operatively connecting the first component to a winch; positioning a second component at a second elevation higher than the first elevation; and configuring cable of a lifting component to: operatively connect to the first component and the second component, connect to and disconnect from a vehicle, and lift the vehicle from the first component towards the second component using the winch.

The invention mainly relates to a device for automatically releasing, maintaining in flight, and recovering a tethered aerostat. The device includes a platform having a rotatably mobile part, a device for recovering the tethered balloon secured to the mobile part, and at least first and second winches. A first cable called umbilical cable is connected to the first winch and has an end provided to be secured to the aerostat. A second cable called sling is divided into at least an adapted mooring portion having an end provided to be secured to aerostat, and a connecting portion connected to the second winch, which connecting portion has a linear mass smaller than or equal to seven grams per meter and a length greater than that of the mooring portion.

A tethered aerostat with a ground based deployment, extended duration and recovery system to accommodate a weather vaning deployed aerostat while maintaining a supply of a lift gas by having a rotatable tether pipe and a hollow tether. Included is a rotatable tether pipe device assembly with rotor and stator components disposed in an air tight housing assembly to provide a ground based gas maintenance system. An aerostat deployment buoyancy control maintenance and combined recovery platform is provided. The tethered aerostat systems and method increase deployment duration and allow more systems to be controlled and maintained on the ground without interrupting aerostat operational capabilities.

A lighter than air craft having an airframe that has at least one tank in the airframe for holding compressed or liquid hydrogen or helium and at least one compartment in the airframe holding an inflatable bladder. The inflatable bladder can be inflated with hydrogen or helium gas from the first tank. There is a vent in the compartment allowing air to exit the compartment when the bladder is inflated and allowing air to enter the compartment when the bladder is deflated. Inflating and deflating the bladder partially controls buoyancy of the craft. Inflating bladders in compartments fore and aft controls pitch and trim.

A method for sheltering a balloon, a blimp, or airship. The method includes obtaining a first guideway by detachably attaching a first plurality of detachable rings to a first side of an outer surface of the balloon, placing a first rope into the first guideway by passing the first rope through the first plurality of detachable rings, attaching a first end of the first rope to a first point of a blanket, and pulling the blanket over the balloon by pulling a second end of the first rope in a first direction pulling the blanket over the balloon by pulling a second end of the first rope in a first direction.
