Electromagnetic Aircraft Launch System
The Electromagnetic Aircraft Launch System (EMALS) is a system under development by the United States Navy to launch carrier-based aircraft from an aircraft catapult using a linear motor drive instead of the conventional steam piston drive. The main advantage is that this system allows for a more graded acceleration, inducing less stress on the aircraft's airframe.
Other advantages include lower system weight, with a projected lower cost and decreased maintenance requirements. The design includes the ability to launch aircraft that are heavier or lighter than the conventional system can accommodate. In addition, the system requires far less fresh water, reducing the need for energy-intensive desalination.
==Design and development==
The EMALS is being developed by General Atomics for the U.S. Navy's newest aircraft carriers. A somewhat similar system, Westinghouse's ''electropult'' had been developed in 1946 but not deployed.〔http://www.theengineer.co.uk/archive/october-1946-westinghouse-unveils-the-electropult/1017387.article〕
