Sorry for the amatuer question... is it possible to have two ski ramps on a carrier? That way you could launch two aircrafts at the same time.
Rhino, they could add another ramp, but not in this deck configuration. They would never add a ramp on that waist sponson because that is at the end of the "runway," and they need that level space there so a landing aircraft that misses a wire can accelerate in full afterburner and escape and fly around and try again. That's what they call a "bolter."

Also, when training new pilots it is fairly regular practice for those pilots to come in and do touch and goes down the landing deck and they need a flat end of runway to do so, which a ski-jump there would interfere with.

So, they would have to completely redesign the deck to accommodate a second ramp...which means the vessel would probably end up being much bigger...and if they were going to do that, they might as well design a CATOBAR carrier.


You have not provided any convincing reason why it couldn't be safely done.
Chuck, I never said it couldn't be done. That was not your original assertion to which I was replying.

Launching aircraft off of the Liaoning is a worthy point to consider and discuss. Having another option would add to their capability, if that is what the intended, or if that is what they wanted. My answer was that it is not what is intended.

There is plenty of evidence that is was not designed or intended to be done. There is no take-off stripe leading over that sponson from the waist position. There is a launch stripe leading from that same waist position over the bow. Ergo, they do not intend to launch over the sponson. If they did, they would mark it accordingly...and they have not. And the Russians never have on the sister ship launching the same types of strike fighters for 20 years. That's enough evidence as to their intent.

My earlier comment was in reference to this statement you made:

Chuck731 said:
It appears the j-15 is taking off from the waist position, as I suspected will become part of normal operating procedure when Liaoning is operational

You indicated that it "appeared" that the J-15 was taking off from the waist position, AND that "as you suspected," it would become a normal part of operations on the Liaoning. My reply was that no, it did not take off from the waist position, and no, it would not be a normal part of Liaoning operations for the reasons I both showed in my earlier post, and now explained. The Chinese themselves have shown their pilots (and by extension, us) how they intend for the launch positions to be used.

In an emergency, or from a purely academic standpoint, could they do it? Perhaps so. But again, what they could do as a one off, and what they will do as a normal part of their operations are two different things.

Does the caption say so? Otherwise what in the picture lets you say so??


Of course not, but I think this is where need to make a leap of faith and logic and consider what is more likely: a waist take off or a touh and go.
Have we ever seen a fixed wing CTOL aircraft take off from the waist without catapult propelling it? No we haven't. Not in kuznetsov, not on US carriers.
Would there be any gain in carrier operation if liaoning could launch a plane from the waist in its current configuration/can a fighter take off from the waist in its current configuration in an operationally useful and safe way? Probably not. Without a ski jump, catapult, or even hold back chocks and jet blast deflectors, you'll have a hard time. That said, I'd like to see the results of a study or naval experiment to see if its possible.
Now finally, would there be a reason for PLAN to conduct such a test at this stage in their carrier operations+have we seen any motivation that they would want to? The answer is overwhelmingly no for both counts.

And these deductions aren't exactly vast leaps of faith based on large amounts of circumstantial anecdote.

Otoh your position can more or less be summed up as "well they still can" combined with "we can't see that they can't," which makes me wonder why you're still tenaciously defending it when you seem so otherwise logical



Edit: just saw Popeyes post, I'll finish it here

If you guys go and check the Chinese Defense Blog you'll see pictures of a new J-15 launching off Liaoning at the waist area.

No, what you see is a J15 with its nose gear in the air coming off the deck which would happen in either case. Its like getting a photo of a American foot ball in the air. It looks the same if it was kicked or thrown.

It's a touch and go... and it's the same picture as in post #826 which started this entire thing

Actually that's the same pic we have been talking about here.

It is not a launch, it is either a touch and go or a bolter. Both of these may look like a launch when they are seen flying over the end of the sponson...but they are not. The PLAN does not intend to launch off of the waist sponson from the waist position.

It is clearly marked for take-off over the bow. Any video of a full take off from that position will show it going off of the bow. Watch from 00:20 until 00:30 in this video and you will see such a take off, and again from 00:40 to 00:52.


[video=youtube;F1H5LHoEcpw]http://www.youtube.com/watch?v=F1H5LHoEcpw[/video]

Then watch the touch and goes on this video, over the waist sponson. But no take-offs. From 00:45 to 00:48, again, especially from 00:50 to 00:55.

Yeah, the radome tip pitot is foldable on the Su-33 as well. Considering J-15 has the same dimensions as the Su-33 while Liaoning's aircraft elevators are most likely the same size as those on the Kuznetsov, I think the Chinese had to copy the folding pitot as well.

As a 554 also uses folding pitot it is obviously standard issue for the serial production J-15. No wonders there since the lift space is just enough to match J-15 with folding pitot. It is though one more case to look for maintenance and not a minor issue.
