The history and application of the kite

A kite is a lightweight tethered glider consisting of several surfaces bonded together. In its simplest form, a kite is a very long-known and widespread toy. In China, Japan, Korea, the Annamites, the Malays and the Maori (natives of New Zealand), the kite has existed since very ancient times. In many cases, for example, among the Maori, kite flying is part of a religious ritual, and the very origin of this sport is associated with religious customs.

In China, the ninth day of every ninth month is called "Snake Day", and on this day almost the entire population is engaged in kiting from nearby hills. In Europe, the invention of the kite is often attributed to Archytas of Tarentum (4th century BC); according to other sources, the kite was transferred to Europe in the 16th century from East Asia.

The most common form of a kite is an acute isosceles triangle, the base of which is adjacent to another, obtuse triangle or semicircle.
The kite is made of light wooden sticks covered with paper or light fabric; often the kite is brightly colored. A tail is attached to the lower end of the snake — a piece of rope, usually six times the length of the snake, with pieces of paper impaled on it. Short pieces of rope are attached to the centers of gravity of both triangles, which are connected to a long thread running to the ground.

In meteorology, a kite was used to lift self—recording meteorological instruments - meteorographs into the high layers of the atmosphere and was thus one of the most important devices used in aerology. There are several types of kites: box-shaped (Hargrave, Marvin and others), semi-cylindrical (In. Kuznetsova), triangular and others. All of them are wooden (pine, bamboo) or metal (duralumin) frames, fastened with steel wire ties and covered with some light and durable material (silk, nansuk).

The triangular-section kite used in aerological observatories was characterized by high lift and was very stable in flight. The highest altitude to which the kite was lifted is 9.600 m (aerological observatory in Lindenberg, Germany). The negative side of the kite is the inability to use it both in very weak (less than 4 m/sec.) and very strong (more than 25 m/sec.) winds. 메이저사이트 는 모바일 친화적이므로 플레이어는 스마트폰이나 태블릿을 통해 이동 중에도 좋아하는 게임에 액세스할 수 있습니다. 모바일에 최적화된 홈페이지로 원활한 게임 경험을 제공합니다.
