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 ...
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 size and manpower requirements of steam catapults place limits on their capabilities. A newer approach is the electromagnetic catapult, such as Electromagnetic Aircraft Launch System (EMALS) developed by General Atomics. Electromagnetic catapults place less stress on the aircraft and offer more control during the launch by allowing gradual ...
The electromagnetic aircraft launch system (EMALS) is likely similar in design to the catapult aboard the US Navy's advanced Ford-class supercarriers.
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 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.
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 Electromagnetic Aircraft Launch System (EMALS) launches aircraft by means of a catapult employing a linear induction motor rather than the steam piston used on the Nimitz class. The EMALS accelerates aircraft more smoothly, putting less stress on their airframes.
