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 Electromagnetic Aircraft Launch System (EMALS) is a type of electromagnetic catapult system developed by General Atomics for the United States Navy. The system launches carrier-based aircraft by means of a catapult employing a linear induction motor rather than the conventional steam piston , providing greater precision and faster recharge ...
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 ]
The United States Navy is developing the use of a linear motor-based electromagnetic catapult system called the Electromagnetic Aircraft Launch System (EMALS) with the construction of the Gerald R. Ford-class aircraft carriers, and a similar system has also been developed for the Chinese People's Liberation Army Navy's Type 003 aircraft carrier.
The United States and China completed the development of electromagnetic catapult to launch carrier-based aircraft using a linear motor drive instead of steam. The electromagnetic catapult is found on the American Gerald R. Ford-class carriers (the electromagnetic aircraft launch system) [6] and the Chinese carrier Fujian.
The flight deck has three electromagnetic catapults (EM catapults) and an angled landing area with arresting gear. [6] As of at least 2024, EM catapults are the most sophisticated aircraft launch technology and are only used on the Fujian and the USS Gerald R. Ford.
Ma has led the development of China's electromagnetic catapult system [3] for launching aircraft from carriers (similar to the Electromagnetic Aircraft Launch System of the United States), which is more efficient than the older steam catapult system.
The United States is replacing carrier steam catapults with linear induction motors. The system is called the electromagnetic aircraft launch system (EMALS). An electromagnetic wave traveling through the motor propels the armature along its length, pulling the plane with it. This system allows more precise control over the launch power, causing ...
