Yuan Class AIP & Kilo Submarine Thread

I think you better do a check again. Its already around the corner and going to be offered for EVs.

That is a prototype stage product, didn't reached the same maturity like the gas turbine powertrain for cars.

The above mentioned basic issues still presents.

Design a long lead time submarine for an unmatured/theoretical basic technology is the best way to blow up your dev budget. See the Ford / F35/ Zumwalt , B-1 and so on.

I only have rudimentary knowledge of batteries, but I'm sure lithium solid-state batteries shares far more commonality with lithium-ion batteries than your examples with their respective competing technology. Also consider that the batteries will have been exhaustively tested before introducing to the mass consumer market.

You mean like next year the solid state batteries will start going into cars?

BYD already makes solid states batteries. But we still dont know if there are any issues that prevents it from deploying them in submarines.

Lithium though is very dangerous for submarines and it carries a lot of risk.

In my not expert view I cant see why solid sate batteries cant be used in a submarine. It would cut down a lot of costs from extra redundancies and safety features that Lithium-based submarines have to use to provide a fool-proof system

Sorry, i meant "blade battery" which is composed of lithium-iron-phosphate (LFP) in a cell-to-pack (CTP) system . It basically eliminates any safety concerns.

BYD is already selling vehicles using this system and I dont why new submarines couldn't utilise this tech.

I beliebe that the NEV battery improvements can directly translate to submarine development

After the Cold War, military electronics technology has fallen behind civilian electronics by generations.

Military is more deeply conservative and more concerned with safety issues. Rightly so.

The still secretive PLAN isn't going to announce such things if they are actually working on such projects.

IMO I would test the technology through tech demonstrators that are unmanned like larger USVs.

Jiangnan has built an experimental midget submarine that appears unmanned and without a sail. It can be a prototype used to test new submarine technologies without endangering the crew.

Wondering about the chinned or notched sails....




New notch sail design on "039C" also points to the sighting of notch sail on the "093A" to not be a fluke and that there is a new design trend going on. The main difference is where on the sail the notch is, low on the 093A and high on the "039C", but somewhat on the middle on the A26.

@Kejora thanks bro and also @Bltizo for the photo, it seems China submarine design is evolving combining both the Russian and European design philosophy, I really like it and I think Type 95 will follow this design as well future Type 93 variants.

Hopefully, new nuke subs will have pumpjet propulsors!

@KampfAlwin same here bro, and also the combat management and control system, I had seen inside photo of YUAN and I'm not impress compared to the European Sub, the placement of those consoles and the ergonomics design is lacking, hope in this new sub those concern had been rectify.
