  2. Magnus effect - Wikipedia

    en.wikipedia.org/wiki/Magnus_effect

    e. The Magnus effect is a phenomenon that occurs when a spinning object is moving through a fluid. A lift force acts on the spinning object and its path may be deflected in a manner not present when it is not spinning. The strength and direction of the Magnus effect is dependent on the speed and direction the of rotation of the object. [1]

  3. External ballistics - Wikipedia

    en.wikipedia.org/wiki/External_ballistics

    External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an atmosphere or in the vacuum of space, but most certainly flying under the influence of a gravitational field.

  4. Flettner rotor - Wikipedia

    en.wikipedia.org/wiki/Flettner_rotor

    Flettner rotor. A Flettner rotor is a smooth cylinder with disc end plates which is spun along its long axis and, as air passes at right angles across it, the Magnus effect causes an aerodynamic force to be generated in the direction perpendicular to both the long axis and the direction of airflow. [1] The rotor sail is named after the German ...

    The Magnus Effect is something most people have never heard of until now that a YouTube clip explaining what it does showed how incredibly cool physics can be. These kids went to a 415-foot-high ...

  6. Rotor ship - Wikipedia

    en.wikipedia.org/wiki/Rotor_ship

    A Magnus rotor used to propel a ship is called a rotor sail and is mounted with its axis vertical. When the wind blows from the side, the Magnus effect creates a forward thrust. The most common form of rotor sail is the Flettner rotor. [3] [failed verification] The wind does not power the rotor, which is rotated by its own power source.

  8. Airborne wind energy - Wikipedia

    en.wikipedia.org/wiki/Airborne_wind_energy

    Airborne wind energy. Airborne wind energy (AWE) is the direct use or generation of wind energy by the use of aerodynamic or aerostatic lift devices. AWE technology is able to harvest high altitude winds, in contrast to wind turbines, which use a rotor mounted on a tower. The term high-altitude wind power (HAWP) has been used to refer to AWE ...

  9. Lift (force) - Wikipedia

    en.wikipedia.org/wiki/Lift_(force)

    Lift (force) When a fluid flows around an object, the fluid exerts a force on the object. Lift is the component of this force that is perpendicular to the oncoming flow direction. [1] It contrasts with the drag force, which is the component of the force parallel to the flow direction. Lift conventionally acts in an upward direction in order to ...
