Kytoon

A kytoon or kite balloon is a tethered aircraft which obtains some of its lift dynamically as a heavier-than-air kite and the rest aerostatically as a lighter-than-air balloon.^[1] The word is a portmanteau of kite and balloon.

The primary advantage of a kytoon is that it remains in a reasonably stable position above the tether point, irrespective of the strength of wind, whereas ordinary balloons and kites are less stable.^[1]

The kytoon has been used for many purposes, both civil and military.
