A kytoon or kite balloon is a tethered aircraft which obtains some of its lift dynamically as a heavier-than-air kite
A kite is a tethered heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create lift and drag forces. A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the fac ...
and the rest aerostatically as a lighter-than-air
A lifting gas or lighter-than-air gas is a gas that has a density lower than normal atmospheric gases and rises above them as a result. It is required for aerostats to create buoyancy, particularly in lighter-than-air aircraft, which include free ...
balloon
A balloon is a flexible bag that can be inflated with a gas, such as helium, hydrogen, nitrous oxide, oxygen, and air. For special tasks, balloons can be filled with smoke, liquid water, granular media (e.g. sand, flour or rice), or lig ...

Stability
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. This can provide good stability even in strong winds. In low or gusty winds a kite can nose-dive, losing a large amount of height even if it recovers. Because a kytoon is buoyant it does not nose-dive and remains in position even in relatively still air."Kite + balloon = kytoon", ''Popular Mechanics'', August 1950, Page 80.Applications
Applications of the kytoon have included: * Raise communications antenna aloft * Commercial advertising * Low-level aerial photography * Raise wind turbines for generating electricity * Raise emergency signals in calm or wind * Meteorological measurements/ref> * Sighting target for conducting geographical surveys * Scare birds away from crops * Recreation

*Aerostat
An aerostat (, via French) is a lighter-than-air aircraft that gains its lift through the use of a buoyant gas. Aerostats include unpowered balloons and powered airships. A balloon may be free-flying or tethered. The average density of the c ...
*Airship
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air.

*Buoyancy
Buoyancy (), or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the ...
*Kite types
Kites are tethered flying objects which fly by using aerodynamic lift, requiring wind (or towing) for generation of airflow over the lifting surfaces.
Various types of kites exist, depending on features such as material, shape, use, or operat ...
