Magnus's Effect презентация

What is "Magnus effect"
As it is clear according to his name, this effect was opened by Heinrich Magnus in 1853 what he has received nothing for, but the phenomenon quite interesting.
If to speak science language, then this physical phenomenon arising at flow of the rotating body with a stream of liquid or gas.

What is "Magnus effect"
The essence of the phenomenon is that the ball at rotation creates around itself air whirl. On the one hand an object the direction of a whirlwind coincides with the direction of the flowing round stream and the speed of the movement of the environment from this party increases. On the other side of an object the direction of a whirlwind to an opposite direction of the movement of a stream, and speed of the movement of the environment decreases. This difference of speeds generates the cross force which changes a flight trajectory.

Use of "Magnus's Effect"
Magnus's effect is used in:
Sport
Wind generators
Shipbuilding
Aircraft industry

"Magnus effect" in sport
The essence of the phenomenon is that the ball at rotation creates around itself a vortex motion of air. On the one hand an object the direction of a whirlwind coincides with the direction of the flowing round stream and traveling speed of the environment from this party increases.

"Magnus effect" in sport
On the other side of an object the direction of a whirlwind to an opposite direction of driving of a stream, and traveling speed of the environment decreases. This difference of speeds generates the transversal force which changes a flight trajectory

"Magnus effect" in wind generators
Widely now in use bladed wind generators in the world unstably and unefficiently work at small speeds of wind. Therefore the wind turbines using Magnus's effect which main advantages are shown at the low, but the most often repeating speeds of wind of 2-6 m/s are very interesting.

"Magnus effect" in shipbuilding
Rotor ships use mast-like cylinders for propulsion. The effect is used in a special type of ship stabilizer consisting of a rotating cylinder mounted beneath the waterline and emerging laterally.

"Magnus effect" in shipbuilding
By controlling the direction and speed of rotation, strong lift or downforce can be generated. The largest deployment of the system to date is in the motor yacht Eclipse.

"Magnus effect" in aircraft
A flettner airplane is a type of rotor airplane which uses a Flettner rotor to provide lift. The rotor comprises a spinning cylinder with circular end plates and, in an aircraft, spins about a spanwise horizontal axis. When the aircraft moves forward the Magnus effect creates lift.
