CV-18 Fujian/003 CATOBAR carrier thread

It is crazy that they allow commercial flights over the shipyard.

The airport was there long before JNCX shipyard moved to the present location. They knew very well they were under the direct landing and take-off path of all airliners to and from the airport. There is no way to alter the landing and take-off flight path. I am sure they have taken all measure regarding exposure of sensitive parts to both airliners and satellites.

Does anyone has any ideia if the turbines for 003 are a new design or if they are the same from the carrier shandong which were based on the soviet design from varyag ?

Given the substantially larger displacement of the ship and the need for more BHP, I would hazard to guess that they are a new design. The old Kitty Hawk had 210MW SHP, 40% more than Kuznetzov class.

Well, they could just add more turbines of the same type.

The Americans probably already have satellites photographing the place with extreme detail every day.

Chinese blogger flying Air China with his Huawei phone will do a better job.

They could use more powerful steam turbines. While the selection of gas turbines might be more limited for China, China is a major maker of steam turbines.

I don't think the Varyag propulsion setup is actually a problem. There's no sign of the Liaoning having had the nightmares the Kuznetsov has had. It's probably more to do with the Russian navy craptastic maintenance (and probably parts problems, given she was built in Ukraine) than a major design flaw. That said, the CV-xx is a fairly significant departure from Kuznetsov class, so I'd be surprised if it doesn't go with a simpler, more modern and more space efficient home-grown gas turbine setup than the old-school steam turbines and oil boilers. New hull, new ideas, new opportunities.

003 need a lot of extra power for electricity (catapults, communication, radar, etc.)

As others have pointed out, steam turbines seem more likely given:
1. Until just a couple of years ago, it wasn’t clear whether the catapults would be steam or EMALS.
2. Steam turbines allow for a natural transition to nuclear propulsion
3. More mature indigenous technology base vs gas turbines.

Clarification: I meant problem in reliability rather than capacity. The whole thing would have to be scaled up ridiculously for the Class 003 and I can't see that being seriously considered given it's not an ideal design to start with.
