What is the reason why kites fly sideways?

The wind is big and small, and the blowing direction also changes. These factors will cause the kite to deviate. If the left end is heavy, you need to reduce the weight, or add a little counterweight to the right end.

If a kite flies in the sky, it is necessary to balance all kinds of forces and moments acting on the kite if it wants to fly smoothly and have good performance. If the balance can't be achieved, there will be various abnormal States in the flight. The forces acting on the kite include lift, resistance, gravity, tension and centripetal force needed for curve movement.

as long as all kinds of forces are equal in magnitude and opposite in direction and all act on the center of gravity, the balance of forces can be achieved. However, the point of action of various forces is not necessarily at the center of gravity, so there is an arm of force (the shortest distance from the point of action of a force to the center of gravity), thus forming a moment (force multiplied by the arm of force equals the moment). If the corresponding moments are equal, the kite can fly normally.

Kite flying skills

1. Kites should not be flown very high.

The main purpose of flying kites is entertainment. Never fly kites high. Because the higher the kite is, it will be easy to have scenes that you can't control.

2. In case of wind, thunderstorm and other weather, take up the line in time and get out in time if necessary.

Flying kites usually requires windy weather, but sometimes the wind becomes very strong. The stronger the wind is, the kite will be difficult to control. At this time, it is necessary to close the line in time and lower the height of the kite. If it is really not good, don't let it go. Take the line home in time in case of thunderstorm, which is not only bad for flying kites, but also prone to being struck by lightning.

3. It is best to wear non-slip gloves.

The kite string looks like an ordinary string, but it is a potential sharp instrument. It is easy to cut your hand when you pay off the string quickly or catch it in a strong wind, so it is best to bring a pair of non-slip gloves to prevent it from cutting your hand.

4. Children should be supervised by adults when flying kites.

Children should choose small kites suitable for children when flying kites, and adults should also look after them at the same time, so as to prevent children from being dragged by strong winds.
