A tethered, moored or captive balloon is a balloon that is restrained by one or more tethers attached to the ground so it cannot float freely. The base of the tether is wound around the drum of a winch , which may be fixed or mounted on a vehicle, and is used to raise and lower the balloon.
A balloon is an unpowered aerostat which has no means of propulsion and must be either tethered on a long cable or allowed to drift freely with the wind. Although a free balloon travels at the speed of the wind, it is travelling with the wind so to a passenger the air feels calm and windless.
A captive balloon tends to drift down the wind and the harder the wind blows, the further the balloon drifts. This leans the tether over at an angle, pulling the balloon lower. On a kytoon, the kite action lifts the balloon, counteracting this pull and holding the kytoon in position. As the wind blows harder, the kite action lifts harder.
The Tethered Aerostat Radar System (TARS) [1] is an American low-level airborne ground surveillance system that uses aerostats (moored balloons) as radar platforms. Similar systems include the EL/M-2083 and JLENS .
German observation balloon launching at Équancourt in the Somme (22 September 1916) German war plane brings down a tethered kite balloon (1918) World War I was the high point for the military use of observation balloons, which were extensively deployed by both sides. The British, despite their experience in late 1800s Africa, were behind ...
Hot air balloon festivals are held annually in many places throughout the year, allowing hot air balloons operators to gather- as well as for the general public- to participate in various activities.They can include races; evening "night glows", or "glowdeos" (in the US), in which balloons are fired while remaining tethered to the ground; and rides.
A tethered helium balloon gives the public rides to 500 feet (150 m) above the city of Bristol, England. The inset shows detail of the gondola. As an alternative to free flight, a balloon may be tethered to allow reliable take off and landing at the same location. Some of the earliest balloon flights were tethered for safety, and since then ...
Drachen kite balloon, showing its characteristic shape. A kite balloon is a tethered balloon which is shaped to help make it stable in low and moderate winds and to increase its lift. It typically comprises a streamlined envelope with stabilising features and a harness or yoke connecting it to the main tether and a second harness connected to ...
