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 same energy is then used to return the carriage to its starting position. An electromagnetic catapult can launch every 45 seconds. Each three-second launch can consume as much as 100 million watts of electricity, about as much as a small town uses in the same amount of time.
Electromagnetic catapults have several advantages over their steam-based counterparts. Because the rate of aircraft acceleration is more uniform (and is configurable), stress on the airframe is reduced considerably, resulting in increased safety and endurance and lower maintenance costs for the aircraft.
Electromagnetic catapult technology already has the ability to launch any aircraft now in the Navy inventory and any the Navy has ordered. With the new launch system’s potential to achieve acceleration forces reaching 14 Gs, human endurance may be one of the few limitations it faces.
Currently, most of the electromagnetic catapults are based on pulse power supply technology. But they have to face challenges such as complicated control circuit, low efficiency in energy transfer and long launching interval, which will limit the development of electromagnetic catapult.
Two crucial technologies that have been successfully developed for electromagnetic catapult are Pulse Power, which controls the electromagnetic catapult's power requirements and ensures precise and dependable launches, and Linear Electric Machine, which produces the electromagnetic force required to launch aircraft.
