PLAN Aircraft Carrier programme...(Closed)

Good to see pictures of J-15 taking off with dummy ordinances. According to the news anchor, they have already performed takeoffs with maximum load. Here is what I said exactly one month ago:

Hopefully there are pictures of a J-15 launching fully loaded in that case, just to settle this ordeal once and for all.

also note, the hovering Z-8 (or whatever helicopter it is) in the video around the 00:36 mark. A good habit, that PLAN are having a helicopter on stand by as the plane takes off, in case something goes wrong.

Those appear to be inert or training weapons. They should weigh the same as a live round.

In my opinion those weapons loaded are dummy/inert/practice rounds. However the important thing for the PLAN is that they weigh the same as the real deal. This way they can test the range of the Flying Shark with a weapons load.

But with that ski ramp they cannot do this. Launch with a full bag of fuel and a full or heavy weapons load. You need a catapult for that..yes this is from back in the day..but I'm sure everyone gets my point.

Before there's any argument I'd like to know what is the max weight take off laod for the J-15 from CV-16? What then would be the range of the aircraft? Thanks!

Come to think of it, Mid-Autumn Festival is just a few days away. If PLAN desires, these few days should be an ideal time to experiment with night operation as there is a full moon available.

I loved the A-7 Corsair II. i worked on that aircraft while at Vought in the late 70's. Great attack aircraft and could loiter for a long while to help the ground troops.

Just had a random thought. If China went straight to EMALS, wouldn't that reduce the amount of structural changes needed for the J-15?

Hmm is that one of the advantages of EMALS? Doesn't it still accelerated the plane to the same speed, wouldn't the force acting on the plane remain the same?

Also, the J-15 could be developed to use the bridle system of catapult launch, which does need nose wheel modification, and I think it acts on a region of the aircraft where strengthening is not required.

The acceleration is smoother and can be adjusted for mass, which puts less stress on the frame. Just what I read.

No, they are going to over design it in any case and the major benefit of EMALS is not less stress on the aircraft it launches, but, rather in terms of the machinery involved for EMALS vs. a steam cat and its pistons, pressure vessels, etc. and their maintenance which is vastly simplified by the electro-magnetic drive system.

Launch speed would be the same, but acceleration would be different, hence force would also be different.

Simply noting a potential side benefit that could save some redesigning costs.
