Abstract. Electromagnetic aircraft launching system (EMALS) is being pursued by various navies around the world to enable assisted take-off but arrested recovery of naval aircraft from aircraft carriers. Currently, either short take-off but arrested recovery (STOBAR) or steam-driven catapult assisted take-off but arrested recovery (CATOBAR)

0. 0. The Electromagnetic Aircraft Launch System (EMALS) is a type of aircraft launching 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. EMALS was first installed on

about the other option ie catapult system for its next 65,000-tonne aircraft carrier, which is still on the drawing board. Further, once decided to go for a CATOBAR fitted carrier, it makes sense to consider the EMAL system, which is superior to the steam catapult
The traditional and battle-tested steam-powered catapult used to launch aircraft from carriers is being replaced by a powerful, electromagnetic-based, closed-loop linear-motor system — maybe.
The U.S. Navy''s new Electromagnetic Launch System will use a linear induction motor and power electronic systems to propel a carriage along a track to

Developed in the 1950s, steam catapults have proven exceptionally reliable. Carriers equipped with four steam catapults have been able to use at least one of them at 99.5% of the time. These have, however, several drawbacks. One group of Navy engineers wrote: "The foremost deficiency is that the catapult operates without feedback control. With no feedback, there often occurs large transients in tow forces that can damage or reduce the life of the airframe." The steam system i

The first is energy storage. Its not difficult even then to make the electric motors required to accelerate a plane like that, but storing the energy required in something that can charge quickly, not take up huge amounts of space, not require constant replacement, and is able to output a huge amount of power for 2-3 seconds is very difficult.
