Nice EMALS on FORD photo. The caption at the other site says of original wrong photo above: "EMALS being installed"
I like this quote from the same MiGflug source: http://www.migflug.com/jetflights/the-a ... erior.html
"... Another feature of the deck on the USS Nimitz is the coating of it. The coating on the surface is constructed so that it is anti-slip, preventing the aircraft to slide during heavy seas and landings, and also heat resistant which makes it possible for STOVL (Short Take Off Vertical Landing) jets such as the Lockheed Martin F-35 Lightning II to land vertically. If the carrier would not have this feature the F-35’s down-facing nozzle would melt the carrier’s surface...."

More on the Advanced Arresting Gear...

Navy to Use Embattled Arresting Gear Technology on Next Supercarrier

A controversial arresting gear system that has suffered delays and spurred congressional inquiries will remain the technology of choice for the Navy's next aircraft carrier, officials with Naval Air Systems Command announced Monday.

Citing continued progress in the test program for the Advanced Arresting Gear developed by General Atomics, officials announced in a release that the system would remain the recovery system of choice aboard the future carrier John F. Kennedy, set to be commissioned in 2020. The Kennedy is the second in a new class of carriers, with the first, the Gerald R. Ford, expected to be delivered to the Navy in April...

Navy officials said the decision to move forward with AAG came on the heels of the 350th recovery of an F/A-18E Super Hornet in December using the new system. Other milestones for testing include the completion of more than 1,400 dead-load arrestments and 351 test arrestments with the Super Hornet, and ongoing commissioning testing aboard the Ford, according to the announcement.

Also... the team that worked out the bugs on the Water Twister were recognized for their achievement.

NAWCAD Commander’s Awards Honor Excellence in Work for the Warfighter
January 18, 2018
Technical advancements and achievements from across the Command were recognized at the 17th Annual Naval Air Warfare Center Aircraft Division (NAWCAD) Commander’s and Innovation Awards ceremony at the Rear Adm. William A. Moffett Building, Patuxent (Pax) River in December.

Advanced Arresting Gear (AAG) Water Twister Integrated Program Team, Lakehurst, New Jersey, led by Karine Mouradian

This team built a three-phase solution and organized a highly-specialized, multi-disciplined team to work in parallel on several design issues with the water twister aboard USS Gerald R. Ford (CVN 78). The water twister, a component of the arresting gear, is designed to absorb 70 percent of the force of an aircraft’s landing against an arresting wire, thereby reducing stress on the airframe during the landing and leading to increased aircraft longevity. The team used advanced analytical methods to support creative redesign and expeditiously responded to new issues on the fielded systems. Throughout all efforts, the team ensured safe operations at the Joint Base McGuire-Dix-Lakehurst land-based test sites and aboard CVN 78, while developing future advanced technical solutions to fulfill the advanced arresting gear mission for the U. S. Navy.

That first story is misleading because it is one year old - obviously things have improved in that one year. So the TWISTED SISTAs got the TWISTER TWISTING again? Cool. :mrgreen:

Actually it appears they are doing good work getting there.

Whenever there is a paradigm change, I always remember the battle to replace the internal combustion piston engine. The engineering there is very long lived, extremely mature, and right at the far edge. But the reality is that to move forward, we will end up with hybrid-electric etc. technologies, for the reason that they have a larger potential down the road.

Now the first such engine technologies will be hard pressed to beat out the range/efficiency of the current 21st century internal combustion engines. In fact they can't .... "yet". But even if they only are as good as the old '55 Chevy 427 4 barrel Holley engine I ran back in the 60's.... That is not a failure!!!!!. That was a dang good motor, and effective for the purpose. If you gave me a Hybrid as good as that '55 Chevy, you'd have nothing to be ashamed about. No it's not a Viper V'10, but it is a good starting place for future maturity.

As near as I can tell they have made this shift with a lot better performance than my 427 example, and it will provide much better capability, down the road, probably sooner than later, as they work out the engineering issues, and get maturation under their belt. Initial adgustment, reliability and maintenance growth pains? Probably ... but it doesn't mean they can't do 400+ cat n traps. They obviously can.

.... I somewhat agree with the analogy but those of us who work with power are slightly disappointed with the "water twister" level of technology. It is an improvement but more like a 235cu. 6cyl rather than the Power Pack 283 '57 Belair. We had hoped for a triple redundant reciprocal of the disk alternators that would recover the launching 121 MJ for a 100klb a/c; or trapping (at least 50%) 60.5 MJ and a 50klb a/c . Maybe DARPA/ NRL will come thru with an electrical retrofit, in the near future.

Not sure if the TWISTER is used now but anyway there are an astonishing number of sHORNET ARRESTS cited - FAAARout!
Advanced arresting gear is coming along
25 Jun 2018 David B. Larter

"The Navy’s next generation advanced arresting gear destined for the Ford-class carriers trapped two new aircraft in May, according to a release from the company. The AAG, which will replace the traditional arresting cable on the Ford-class flight deck, was used to trap both the C-2A Greyhound carrier on-board delivery aircraft an an E-2D Hawkeye. Both traps occurred a the Runway Arrested Landing Site in Lakehurst, New Jersey.

In a release, General Atomics said the test represented a new phase in the development of the technology. “Since the carrier’s July 2017 commissioning, the AAG system aboard [the carrier Gerald R. Ford] has successfully arrested the F/A-18 Super Hornet 747 times,” Rolf Ziesing, an official with General Atomics’ electromagnetic systems division. “We are now in the next phase of AAG capability and performance testing targeting heavier, prop-based C-2A, E-2C and E-2D aircraft.

“We’ll continue both roll-in and fly-in testing throughout the summer. Once RALS testing is completed, the aircraft will be cleared to begin testing aboard CVN 78.”..."

Not sure how one measures 'fine' - my association with that word is WX or 'fine tuning' but if "... the AAG system aboard [the carrier Gerald R. Ford] has successfully arrested the F/A-18 Super Hornet 747 times,” Rolf Ziesing, an official with General Atomics’ electromagnetic systems division..." somehow or other these 'arrested developments' got off again.

Water twister implies some sort of stator-impeller being drawn through liquid to drive some sort of permanent magnet rotor recovering kinetic energy back into electrical energy, kind of on the principles of how an automatic transmission works under a load.

AAG being upgraded in GERALD (CVN78)
Carrier USS Gerald R. Ford Enters Year-Long Post-Shakedown Maintenance and Upgrade Period
16 Jul 2018 Ben Werner

"After spending 81 days at sea spread out during eight steaming events, USS Gerald R. Ford (CVN-78) is back at Huntington Ingalls Industries Newport News Shipbuilding for a year-long maintenance and upgrade period. For the next year, Ford’s post-shakedown availability (PSA)/selected restricted availability (SRA) will concentrate on installing the aircraft carrier’s remaining combat systems, completing any deferred work...

upgrading the advanced arresting gear....

...Since commissioning on July 22, 2017, Ford has successfully completed nearly 750 shipboard aircraft launches and recoveries, nearly double the approximately 400 launches and recoveries originally planned, according to the Navy. Ford also certified its air traffic control center, its JP-5 fuel system, demonstrated daytime and nighttime replenishment capability and the ship’s defensive systems."..."

FARNBOROUGH: Raytheon JPALS landing aid nears serial production
17 Jul 2018 Michael Gubisch

"Raytheon intends to reach operational capability of its military joint precision approach and landing system (JPALS) this year, and start production in 2019. The manufacturer has been testing the system since 2015 and earlier this year conducted landing trials with a Lockheed Martin F-35B Lightning aboard the US Navy’s amphibious assault ship USS Wasp.... [jeepers USN has been testing JPALS on CVNs for YONKs buddy - since 2015 - ya coulda said so]

...Raytheon sees opportunities for further deployment beyond the US Navy. Scott says the manufacturer has had enquiries by the US Air Force and Marine Corps for a land-based system. A prototype has been developed, and Scott says he expects a trial to begin within a year. He adds that the system could provide precision landing capability at an airfield within two hours, while installation of conventional ground infrastructure would typically be a matter of months.

Raytheon vice-president of navigation, weather and services Matt Gilligan says: “There are many fixed- and rotary-wing aircraft around the world and across the services that deploy to harsh, low-visibility environments where JPALS would be extremely valuable.""
