Default Launching and Landing Aircraft With Magnetics

Very cool!

Must take a pretty strong magnet to launch and stop an aircraft.

Quote:
The USS Gerald R. Ford, the Navy’s newest aircraft carrier, successfully launched and landed an aircraft with advanced digital, magnetic technolgy, which replaces the older steam-driven catapult system.




The succesful missions Friday came less than a week after President Trump commissioned the nearly $13 billion ship in Virginia.

"Today, USS Gerald R. Ford made history," said Adm. Phil Davidson, commander of the U.S. Fleet Forces. "Great work by the Ford team and all the engineers who have worked hard to get the ship ready for this milestone."

Actually it is probably a series of fairly large Electro magnets that are energized in series from the starting point out to the lift-off point for the aircraft being launched. Landings I would think will be something similar.

I guess the magnetic forces don't interfere with the avionics on board the aircraft. Seems like they would.

You can shield electronics from EM sources... Which I would suspect is a necessity on a military vehicle of any sort. Also, there are a number of ways this could be set up so that the magnets move a billet of some sort that is somehow linked to the shuttle/bridle that actually moves the aircraft. In that case the deck would be acting as a fair amount of shielding as well.

As I understand it (I'm a nuke, not a magnet guy), the system uses linear induction motors. I seem to recall that such systems have been used on a variety of transport forms (small public shuttles, experimental vehicles, and I believe the bullet trains as well). To my knowledge there are no adverse effects on the electronics carried by passengers, and most personal electronics are not exactly what one would call well shielded.
