To launch a kite into the air the force of lift must be greater than the force of weight. Drag is caused by the difference in air pressure between the front and back of the kite and the friction of the air moving over the surface of the kite. Drag is the backward force that acts opposite to the direction of motion. An airplane generates thrust with its engines, but a kite must rely on tension from the string and moving air created by the wind or the forward motion of the kite flyer to generate thrust. Thrust is the forward force that propels a kite in the direction of motion. The force of weight pulls the kite toward the center of the Earth. Since the speed of the air above the kite is greater than the speed of air below, the pressure above is less than the pressure below and the kite is pushed into the air and - Tada - lift! Weight is the downward force generated by the gravitational attraction of the Earth on the kite. Daniel Bernoulli, an 18th century Swiss mathematician, discovered that the pressure of a fluid (like air) decreases as the fluid speeds up. Kites are shaped and angled so that the air moving over the top moves faster than the air moving over the bottom. Lift is generated by differences in air pressure, which are created by air in motion over the body of the kite. Lift is the upward force that pushes a kite into the air. Lift, Weight, Drag, and Thrust) affect kites in the same way they affect airplanes, and anything else that flies. The kite pivots and dives about the point where the bridle connects to the control line. In flight, the kite is connected to the kite flyer by the control line, which is connected to the kite by the bridle. The bridle and the control line help the kite flyer control the kite. Paper, fabric, or plastic is then stretched over the framework, turning it into a sort of wing. The framework is usually made from a lightweight material like wood or plastic. The kite body is made up of a framework and outer covering.
Most kites have three main components: the kite body (which comes in many different shapes and sizes), the bridle (or harness), and the control line (or tether). A kite is a heavier-than-air object that flies… just like an airplane. To understand how a kites flies, you need to define what a kite is. All of the incredible kites and amazing activities made me wonder how many people actually understand how kites fly. It featured lots of kite activities, cultural crafts, indoor kite flyers, and Japanese kite masters. Recently the National Air and Space Museum hosted Kites of Asia Family Day.
