A kytoon or kite balloon〔(Popular Mechanics Mar 1958 )〕 (a portmanteau of kite + balloon) is a tethered aircraft which obtains lift both dynamically as a heavier-than-air kite and aerostatically as a lighter-than-air 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.〔 The kytoon has been used for many purposes both civil and military. The inflation gas need not be of lower density than the fluid stream in which it is operated. It is sufficient that the kytoon be part balloon and part kite. Hydrogen, methane, air, helium, etc. may be used to inflate the balloon aspect of a kytoon. ==History== The kite balloon was invented by Domina Jalbert〔 in 1944 as patent (US2431938 ). and later became known as the kytoon. He furthered his attention on kite balloons also with another patent filed on August 31, 1945 titled "(Kite Balloon )" The Allsopp Helikite is a modern helium-filled example. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kytoon」の詳細全文を読む スポンサード リンク
