![]() ![]() With no feedback, there often occurs large transients in tow force that can damage or reduce the life of the airframe." The steam system is massive, inefficient (4–6% useful work), and hard to control. One group of Navy engineers wrote: "The foremost deficiency is that the catapult operates without feedback control. However, there are a number of drawbacks. Carriers equipped with four steam catapults have been able to use at least one of them 99.5% of the time. It also reduces the carrier's requirement of fresh water, thus reducing the demand for energy-intensive desalination.ĭeveloped in the 1950s, steam catapults have proven exceptionally reliable. Compared to steam catapults, the EMALS also weighs less, is expected to cost less and require less maintenance, and can launch both heavier and lighter aircraft than a steam piston-driven system. Its main advantage is that it accelerates aircraft more smoothly, putting less stress on their airframes. Ford-class aircraft carrier, USS Gerald R. EMALS was first installed on the lead ship of the Gerald R. The system launches carrier-based aircraft by means of a catapult employing a linear induction motor rather than the conventional steam piston. The Electromagnetic Aircraft Launch System ( EMALS) is a type of electromagnetic aircraft launching system developed by General Atomics for the United States Navy. And by extension something is seriously wrong with Americans, or at least 62 million of them, that they would vote someone like this as our President.For the general type of catapult, see Electromagnetic catapult.Īn illustration of the EMALS A drawing of the linear induction motor used in the EMALS Something is seriously wrong with Trump’s brain. Trump supporters are either predictably claiming this isn’t real - “fake news” - or some are even defending this as a stroke of brilliance. ![]() They should not be allowed to forget they voted for this idiot the way someone who drove drunk and wrecked his car, killing someone should be allowed to forget he did that.Īnyhow, if you really want to get depressed look at the comments section of The Hill piece and their Facebook page. Not just because I want to mock them, but putting someone this fucking ignorant in charge of the world’s greatest military arsenal and fighting force is extremely dangerous. But 62 million Americans made this moron President. They should never be allowed to forget that they voted for this moron. I get that.īut that does not excuse their vote for this moron. On a more serious note, look, I realize that, in addition to being motivated by bigotry or at least a willingness to overlook bigotry, some Trump supporters did have real economic anxiety. I then laughed my ass off and thought of this: You going to goddamned steam, the digital costs hundreds of millions of dollars more money and it’s no good. I said what system are you going to be–"Sir, we’re staying with digital." I said no you’re not. And I said–and now they want to buy more aircraft carriers. What is digital? And it’s very complicated, you have to be Albert Einstein to figure it out. You see that sucker going and steam’s going all over the place, there’s planes thrown in the air." I said, "Ah, how is it working?" "Sir, not good. I said you don’t use steam anymore for catapult? No sir. He said well, we’re going to this because we wanted to keep up with modern. So I said what is this? Sir, this is our digital catapult system. You know the catapult is quite important. And sure enough here’s what it read: On the future USS Ford-class carriers So I thought, “No way, I have to see the transcript, there has to be some context that makes this seem less bad somehow.” So I went ahead and looked at the transcript from the actual interview with Time Magazine.
