Abstract
Kites and airfoils designed in such fashion that the possibilities to observe the process by which the kite or airfoil is made airborne are maximized. Each time a gust of wind appears, the kite or airfoil rises automatically up a fixed pole which passes through it, without further direct intervention. When the airflow or wind abates, the kite or airfoil descends the pole, and rests on a restraining device located on the pole at a level higher than its lower-most level until the next gust of wind or an increase in the airflow lifts the kite or airfoil up again, and so on. The restriction of the pole also keeps the kite or airfoil within a short distance of the observer who can have a closer and better view of the process of ascension of the kite or airfoil up the pole. The applications of this invention include scientific instruments, childrens's toys and advertising devices. One embodiment of the invention is a kite which is designed to use the radio antenna of an automobile as its pole.
