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.

What would be the point? As things stand, you can already stagger launch two fighters off the ski jump within less than a minute of each other if desired, and you really do not want to, or really need to loft birds any faster as otherwise you would cut deep into your safety margin.

The only way you could launch two aircraft at the same time without unacceptably high risk of accidents is if you had the second ski jump on the angled deck, but that's a non-starter since a ski jump on the angled deck will total any birds that misses the trap.

No. That (again) is either a touch and go, or a wave off. The J-15 will not take off from the waist position over that sponson. It is not designed for that, or intended. Same is true on the Russian Kuznetsov with their SU-33S..

As has been shown numerous times, the waist launch goes up over the ski-jump.

You have not provided any convincing reason why it couldn't be safely done.

In order to take off from the angled deck the craft would have to be striped clean and starting from three quarters of the decks length astern. The pitch of the airframe would mean it would drop off the deck and have to be at open afterburners. In order to generate additional lift needed to allow it to fly as opposed to drop into the drink. The whole reason for the ramp is to allow the additional angle to make up for loss of the extra kinetic energy offered by cats. The ramps altitude and pitch gives you that extra few seconds for the jets power to take hold and generate proper lift.
using the angle may be possible but you give up a lot of the jets capacity and safety.

Unless you can quantify the loss of margin, it is all idle speculation whether lack of a ramp on the sponson reduces j-15 takeoff below acceptable threshold or not.

The fact that there is a ramp on the Kuznetsov class already proved that lack of ramp would be detrimental to the take-off capability of an aircraft.

You can't have ideal set up for take off everywhere. The question is can take off still be safely performed off the sponson and would the carrier's effectiveness profit from it.

If the kuznetsov class could conceivably launch fighters off the waist safely or under operational standards, then I'm sure the soviet designers would have considered plugging in another set of hold back chocks and jet blast deflectors from which to launch jets.

The question is academic, because maybe a flanker can fly from the end of the landing strip, right at the aft of the ship, but what kind of payload could it hold? And more importantly, how significantly would it impede flight operations.


And the original point you raised is still false, that is to say, the picture of the J-15 is likely of a touch and go rather than some kind of bizarre non catapult propelled waist launch.

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