Retired US Navy vice admiral named technology helping "revolutionize" the use of aircraft carriers

40

Retired American Vice Admiral Lewis Crenshaw has published an article in which he reports on an important direction in the development of an aircraft carrier fleet USA. Attention was drawn to the fact that the United States has recently been paying special attention to this issue (the development of the aircraft carrier fleet) - with publication in various specialized media. More recently, a material appeared in the US press, where it was reported about the possibility of developing an aircraft carrier fleet by putting into service unmanned carrier-based aviation refuellers.


Vice Admiral Crenshaw names another technology that is helping the United States "revolutionize" the use of aircraft carriers. This technology is a retired senior military man who served in the navy for about 37 years, according to EMALS. - an electromagnetic system for taking off carrier-based aircraft from aircraft carriers.

Lewis Crenshaw:

Equipping the latest aircraft carriers such as Gerald R. Ford with EMALS systems makes it possible to increase the number of training missions to 160 per day under normal conditions and up to 270 combat missions in wartime conditions. This is a third more than for Nimitz-class aircraft carriers in peacetime, and 12,5% ​​more than in wartime. This means a significant increase in the efficiency of warships.


Asynchronous motor EMALS


The retired vice admiral of the US Navy notes that the improved technology of electromagnetic catapults (systems for taking off carrier-based aircraft) allows you to launch not only manned aircraft, but also drones, including the same ones - refueling, which were mentioned above.

Vice Admiral Crenshaw:

For example, when fully optimized, EMALS will go from cold start to ready to launch aircraft in about 15 minutes. Steam catapults take hours and significantly more energy to reach the same level of readiness, and this leads to the depletion of critical resources - for example, fresh water on a ship.

Crenshaw said the groundbreaking idea of ​​using EMALS will remain relevant to all Ford-class aircraft carriers (up to 12 planned) for decades.

      The problem is not in the linear motor, but in the energy storage for it. The power during operation of the catapult is comparable to or exceeds the full power of the aircraft carrier's power plant.

      "Linear motor invented ours"
      For an Englishman or amer, you have a very good Russian!
      Because OUR is related to both England and the United States. In the USSR, they could use other people's patents / inventions for free and with pleasure - no one there really bothered with using someone else's intellectual property.
      “The history of linear motors can be traced back at least, from the 1840s to Charles Wheatstone's work at King's College London, but Wheatstone's model was too ineffective to be practical. A possible linear induction motor is described in US patent 782312 (1905; inventor Alfred Zeden from Frankfurt am Main) and is designed to drive trains or elevators. German engineer Hermann Kemper built a working model in 1935. In the late 1940s, Professor Eric Leithwaite of Imperial College London developed the first full-size working model. "

      "Did they bring EMALS to mind?"
      Nearly.
      “According to James Geerts, a US Navy assistant, the recent problems causing the temporary shutdown of the EMALS on board the USS Gerald R Ford (CVN 78) aircraft carrier during sea trials do not indicate a problem with the system as a whole, the secretary said. research, development and acquisitions.
      "Nothing we have seen, nothing I know, and nothing we talk about is a mine or an Achilles heel in the system," Gerts told reporters during a June 18, 2020 teleconference. "

    One flight every 6 minutes. Almost half an hour to assemble the link. And against whom to fight? Papuans who have no air defense. Isn't it expensive?
    Or a group must have at least 2 aircraft carriers.

            Well, this is a classic: connecting the PU NAR connectors on the catapult is long and dangerous, let's connect them immediately when the NAR is suspended - we will save time.
            OK, hooked up. After that, when the aircraft switches to on-board power, the pulses arising in the aircraft network pass to the launcher - and launch the NAR into the Skyhawk standing opposite. But the instruction was written precisely to prevent this: if its instructions were followed, the launcher was physically connected to the plane's network after the "transient processes" had calmed down, and even when there was only an empty deck and an ocean in front of the plane.

        1. Minute thirty-three takes time from the start of the movement, from the cutoff of the soft starter to the stop at the 3rd catapult.
        2. 4 sec raise the shield.
        3 sec the shuttle arrived and the plane became hooked (the shuttle was traveling 34-35 sec) - (at the moment of the hook to the shield
        rolled up another plane)
        4. Thirty minutes - checking and preparing for takeoff - (here I think it will be possible to shorten the time if
        "fix")
        5 sec - take off
        Total, excluding start-up and warm-up - the whole cycle took 4 minutes. (And the extreme ones also pull with tractors) wink

        Where did you get such nonsense, 10 minutes for the exadril? Preparing for a second flight (taking into account wartime and combining some operations and canceling some) - about 20 minutes. And if the suspension is normal, then all 30-35. The number of technical staff is limited, especially the lack of gunsmiths.

          If you are talking about an aircraft carrier, then it takes 2 to 2,5 hours to prepare for a repeat flight.

          The reason is not the lack of technical staff, but the lack of technical training positions and the incomplete possibility of using elevators, since they are also used as positions for pre-flight training.

          The admiral has given you time, or with mathematics badly 240 sorties (training) per day, 10 sorties per hour. Then count yourself. And this is takeoff-landing. To make it clear. In the regiment (any) flight shift is 12 hours (direct flight time is 8 hours). We planned 6 sorties on each side - with almost every sortie a B-P (P-50-75 -1 piece + 15 shells) or NRS-P (4 P-5 + 15) range. but there was max 5 on board. Preparation for a second - about 25 minutes. At the same time, gunsmiths have a soapy bottom. Combining any work with the work of gunsmiths (when suspended) is strictly prohibited, suspension is an extreme type of work, after which only takeoff

        This is the FIRST crash. So I advise you to knock. As an "expert" in AVIATION. THE AERODROME IS VISIBLE "SOFA". I described that briefly, what and how. I will add that in preparation for the re-run, TWO lanes should be free on the deck - takeoff and MANDATORY landing. Then look at the plan of the aircraft carrier and think how many planes can be placed on the remaining free space for preparation and repeated flight, taking into account the distance between the planes of 1-1,5 m.

    To increase the frequency of departures by a third is not critical. It’s just an evolution of existing capabilities, without a radical breakthrough.

    This improvement does not correct the main disadvantages of aircraft carriers in the form of a limited range of aircraft (compared to modern anti-ship missiles), vulnerability to modern means of attack, the impossibility / difficulty of using AUG against an equal or nearly equal enemy.
    Even unmanned tankers are a half measure.
