That steam powered catapult system is pretty much a marvel of engineering to begin with. Moving to the electrical one will probably have more control and be safer, but it's a lot to contend with. Never ceases to amaze me though, the amount of power to control and thrust an aircraft of that weight off an aircraft carrier in such a short distance. I wonder how much power it takes to launch that bird? Between this and the railgun thing I'd say the US Navy is getting pretty good and modern.
The big difference between steam and EMALS catapults is in how they transfer force to the plane. With a steam catapult, max force is applied at release and then drops off as the shuttle moves down the cylinders due to pressure drop off and greater space that pressure is expanding into. With EMALS, the force applied to the plane is at least constant, or can actually increase as the shuttle travels down the rails. What this means in practice is a "softer" launch on the plane and so less damage done. (Being grabbed by the front landing gear and thrown into the sky has got to be hard on the front gear components).
switching cat systems on carriers from steam to electric is all going to come down to three things....reliability, cost of maintenance, and performance......and it looks as if performance is at least equal, if not more powerful.....
I'm not sure a runway test(by itself) gives much legitimacy to the system, since the aircraft is still in ground effect after it leaves the catapult. Then again, if it gave it the Super Hornet the same speed it would off a carrier's steam catapult, it EMALS seems to be doing its job. Oh, and I forgot the carrier usually steams into the wind.
So now technically they can put this launcher anywhere on ships or land and have a tactical launch of drones or planes in remote locations. Good and bad.
Did they do 50 shots per day in a 5 day week on this test unit? All we see is one or a few shots, no summary of a trial week simulating operational conditions. USS Nimitz is scheduled for decommissioning in 2025. The date on EMALS, and all ships depending on it, keeps getting pushed out. Write your representative. USS JFK (79) may be the first to deploy. It may have a more reliable edition of EMALS.
Jimmy Doolittle and his raiders launched 16 B25 bombers off the deck of the USS Hornet in 1942. They had no catapults. Instead of trying to reinvent the wheel, why don't we just use raw jet propelled thrust?

British Invention..😊
The rail gun is also quieter and will take up less space overall.

And the EMALS will be faster due to physics. There is no inefficiency with electric motors launching objects as there is almost no acceleration lag.
whoa wait where's the steam? ;)
That's going to take a little while to get use to seeing.
Am I correct to assume some of this borrows from railgun technology?
It is absolutely a railgun technology difference is it's larger
@@Supergolem12345 and slower, rail gun speeds will destroy aircraft.
@@jayasuriyas2604 That's right and also the aircraft carrier
Not really, it's a linear motor. Railguns operate on different principles.
@@SynchronizorVideos A rail gun most definitely IS a linear motor device. So yes they do operate on the same principles in that respect.

Pulling the cat cylinder is a pia.
Good work.

This system would deliver more power faster.
how the fuck do they reverse the polarity of the source connections to pull back the launcher to its original position ?
Maybe it is mechanically pulled back into place?
It's an AC linear induction motor. The electronics can move it either direction.
Could it be susceptible to EMP attack?
@Sarina Freeman continuous electromagnetic _pulse_ ?
well the ship and planes arent shielded for that so does it even matter lol
He didn’t use afterburner for takeoff
Why would they?
off it goes

Sweet.
Прикольно, спасибо наука и прогресс за ссыль.
Я точно знаю?
now all they need to do is build a boat under it...............

i dont understand is that succesfull or not?
