CATAMARAN — ROTOR-SAILCATAMARAN — ROTOR-SAILI want to tell readers about the catamaran, the movement is carried out with the help of Magnus effect. The Magnus effect is that when an airflow of the rotating body formed a force perpendicular to the direction of flow. As the cylinder rotates, for example, close to its walls the layers of air begin to move in a circle, making one side of the rotating body increases the speed around a cylinder flow, and on the other side a decrease. As a result, the surface of the cylinder are formed by areas of increased and reduced pressure, which leads to the formation of forces, which can be used for ships. It is this force that changes the direction of flight of the “cut” balls in tennis and football.
