    LOL I'm wondering about the weight of your "more ammo", and about the number of fuel trucks needed to generate the electric power

    CG of Type 003 - CV-18, flat-top, conventional but purported to be with electric catapaults capability....
    ..not sure if posted before?..

    Is there a reason why the catapults converge on the 18th while they are parallel on the 19th?

    The CG also shows 4 catapults, while rumors suggest that there will only be 3 on the 003.

    And a pretty inaccurate one too ... the author has already gone out of his/her way to include navalized J-20s in the second photo.

    There is another type of Arresting Gear system studied by Naval University of Engineering. The programme received state funding around 2013, and published one of its outcomes in 2016.

    http://202.197.9.112/gfkjdxxb/ch/reader/view_abstract.aspx?file_no=201606008&flag=1
    Things worth to note:
    1. This is not the system shown on CCTV program. That system is in the same principle as AAG from General Atomics.
    2. The CCTV system and AAG both use "fluid turbine" aka water twister as the main energy absorbing device. The electrical motor in such system is to complement (in a less contributing role) the fluid turbine. The electrical motor is also part of the control system to provide variable torque during the arresting.
    3. The system in this article removes the "fluid turbine" using the motor as the only device. It is therefor a pure electromagnetic arresting gear in the same technology league as EM cat.
    4. The AAG and CCTV system therefor is a "electro-mechanic" arresting gear. Not a real or pure electromagnetic arresting gear in the same league as EMALS or Chinese EM cat.
    Quote from the research paper:
    Translation
    Quote from GA patent Turboelectric arresting gear
    From here, it is clear that the motor is of fine tuning the torque rather than being the main energy absorber.

    From your own quote: "It's character is solely using electro motor as the energy absorbing and adjustment device." If this to be trusted, it would be both the fine torque tuner and energy absorber.

    First to clarify, it is my translation of the original Chinese paragraph from the research paper that was quoted, not my own words.

    Secondly, your understanding is correct.

    P.S. if you expect an answer/reply from me, please reply to my post or @me so I would receive a notification in my mail box, otherwise your post would have gone unnoticed.
