technical field

Background technique

A tethered balloon is a lighter-than-air, unpowered aerostat that has a bladder filled with lighter-than-air gas, which creates an upward buoyancy. The mooring balloon system includes mooring balloon spheres, mooring cable assemblies, mooring facilities and ground comprehensive support facilities. The tethered balloon is suspended in the air by buoyancy, and the sphere is connected to the ground anchoring facility through a mooring cable, and the height of the sphere is adjusted by adjusting the length of the lanyard, thereby providing a quasi-static aerial platform for other equipment.

A typical tethered balloon lift-off platform takes the tethered balloon as the core and consists of a sphere, an anchoring facility, a mooring cable, a payload, and a ground control system. The mooring cable is divided into main cable, nose lanyard and side lanyard. In the mooring state, the sphere is restrained on the mooring facility by the nose lanyard at the nose cone of the sphere and the side lanyards on both sides.

Among them, on the mooring facility, the position where the nose lanyard is connected to the mooring facility is the end of the nose tower. When the ball is anchored, the nose lanyard needs to be gradually tightened on the nose winch. Usually, the nose winch will be placed at the bottom of the anchoring facility for easy operation by personnel. Therefore, the end of the nose tower not only needs to limit the position of the spherical nose cone, but also needs to flexibly turn the nose lanyard to the nose winch at the ground.
