The EMALS uses a linear induction motor (LIM), which uses alternating current (AC) to generate magnetic fields that propel a carriage along a track to launch the aircraft. [5] [6] The EMALS consists of four main elements: [7] The linear induction motor consists of a row of stator coils with the same function as the circular stator coils in a conventional induction motor.
Basic diagram of an onager, a type of catapult. A catapult is a ballistic device used to launch a projectile a great distance without the aid of gunpowder or other propellants – particularly various types of ancient and medieval siege engines. [1] A catapult uses the sudden release of stored potential energy to propel its payload.
Dianna Leilani Cowern (born May 4, 1989) is an American science communicator.She is a YouTuber; she uploads videos to her YouTube channel Physics Girl explaining various physical phenomena.
A mass driver or electromagnetic catapult is a proposed method of non-rocket spacelaunch which would use a linear motor to accelerate and catapult payloads up to high speeds. Existing and proposed mass drivers use coils of wire energized by electricity to make electromagnets , though a rotary mass driver has also been proposed. [ 1 ]
An electromagnetic catapult, also called EMALS ("electromagnetic aircraft launch system") after the specific US system, is a type of aircraft launching system. Currently, only the United States and China have successfully developed it, and it is installed on the Gerald R. Ford -class aircraft carriers and the Chinese aircraft carrier Fujian .
The service offers on-demand content and linear, live TV-style streams from its VoD catalog. Programs cover factual content including science, history, mathematics, technology, robotics, and nature. [36] It also offers content for children and original programming, [37] along with a Kids Mode option to filter out inappropriate content. [38]
MinutePhysics is an educational YouTube channel created by Henry Reich in 2011. The channel's videos use whiteboard animation to explain physics-related topics.Early videos on the channel were approximately one minute long. [2]
The rotating concept. If the orbital velocity and the tether rotation rate are synchronized, the tether tip moves in a cycloid curve. At the lowest point it is momentarily stationary with respect to the ground, where it can 'hook' a payload and swing it into orbit.
