An easy extention of a telescopic rod. The telescopic rod extends in the axial direction by a gas forcibly fed to the inside and is provided with a posture control means.

Provided is a flight vehicle operating method including: mooring a flight vehicle to a mooring unit by a cable; reducing a weight of the flight vehicle, increasing the flotage of the flight vehicle, or increasing the flotage of the flight vehicle while reducing the weight of the flight vehicle, by using a first flotation adjuster; floating the flight vehicle at a suitable altitude in the air; increasing the weight of the flight vehicle, reducing the flotage of the flight vehicle, or reducing the flotage of the flight vehicle while increasing the weight of the flight vehicle, by using a second flotation adjuster or a propelling unit of the flight vehicle; and releasing the connection between the flight vehicle and the mooring unit and withdrawing the cable.

The current invention concerns an improved system for cargo delivery through (unmanned) aerial vehicles (preferably UAVs or drones) to specifically designed home stations. Additionally, a method is described according to which the system of the invention functions.

A portable launch rig (PLR) may include a support structure including two side supports defining an interior space for lifting and filling a balloon envelope of a balloon. Wheels on each of the side supports enable the PLR to be moved in various directions in order to prepare the PLR for launching the balloon. The side supports are connected by a lateral support beam having a pair of cranes arranged thereon. Each crane has an arm arranged over the interior space that is connected to a spreader beam. The spreader beam includes a lift assembly configured to lift and inflate the balloon envelope within the interior space. The PLR includes a platform and perch for supporting and moving the balloon envelope. A door assembly of the PLR includes a plurality of hangar doors configured to block wind from a respective direction of each hangar door entering the interior space.

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.

A device for controlling the ground clearance of an airship, the airship being provided with two lateral anchoring points, comprises: a frame on which a weight is fixed; two (rigid) arms each having a proximal end that is articulated on the frame, and a distal end; means for moving the distal end of each arm between a retention position in which each distal end is in contact with a lateral anchoring end of the airship that is configured to be connected to the distal end, and an unlocked position in which there is no contact between the airship and the docking station; and means for detachably fixing, in the retention position, the respective distal end of each arm on the associated respective lateral anchoring point.
