This energy allowed for the linear motors to propel the launching shuttle down the catapult track in excess of 180 knots before bringing the shuttle to a stop at the end of the track. The next phase of EMALS testing, scheduled for this summer, will involve launching "dead-loads" off of the bow of CVN 78 into the James River.

What Type Of Catapult Is Used Today On Aircraft Carriers?

Once the magnetic energy is created from alternating current (AC) electricity, the coils around the catapult of the opposite polarity of the launch bar push the attached aircraft to take off speed.

There are 2 principles to grasp: 1. Energy will only travel between energy stores; it will not "stop" part way between the stores and it won''t travel to something that isn''t an energy store. 2. Energy will only travel on certain energy "pathways". The first rule is pretty obvious, I hope, so no more needs to be said.
