Therefore my hypothesis of 8 diesel engines was only a low risk choice, since in the CODAD version with 4 diesel engines it has already been tested on at least the SAHAND 74, a possible choice, if the others are not viable.
.
I will admit that my knowledge in regards to ships and their propulsion is very low. So keep that in mind. However, as an engineer with fundamental knowledge regarding combustion engines, gears and shafts on the one hand and gas turbines and generators on the other, I have to say that to me it is not so clear why the aforementioned is more of a low risk. 8 engines will need an intricate gear and shaft integration. So the overall system is IMO more complex than gas turbine + generator + electric motor.
Also I don't think we need to compare so much with other countries. Many seagoing nations had 50+ years experience with combustion engines before introducing gas turbines. Obviously their legacy will have made the transition difficult. Iran on the other hand has very recently mastered both combustion engines and gas turbines.
In conclusion, my dream scenario would be for Iran to develop extremely robust gas turbines because that would be easily scalable and the overall solution is IMO simpler and more elegant.
MGT-80 is German design , the rest I don't knewDo U know if these MGT series are German (siemens) designs or Iranian design..I assume all components are now built in Iran.
Iran doesnt just build them it also redesigns and improves them considerably as we saw with the MGT-70.I suspect this was one of the reasons why siemens did partially honor its deal to supply iran with F Class turbine technology to enable the local manufacturing,and redesign too no doubt,of F Class turbines in iran.Do U know if these MGT series are German (siemens) designs or Iranian design..I assume all components are now built in Iran.
Do not use facts and logic with @VEVAK, it escapes him.
This man is saying use foreign engines on a destroyer and then follows up with blind confidence that Russia and China would supply Eastern engines.
It’s as if for the last 30 years Iran hasn’t been screwed over in engine technology for aircrafts,tanks, etc. but suddenly Russia and China will line up to provide Iran’s destroyer fleet access to engine tech. I’m still waiting for the RD-33 Iran ordered in 2003 for Shafaq to show up. Maybe Vevak can reach out to Russia customer service and see what the hold up is?
Like I said Iranian engineers are keenly aware of the challenges they face. The French engine fiasco showed that even for a frigate the West will not allow Iran easy access. So imagine what would happen if Iran tries to build Destroyers and Cruisers? You can be damn sure that US and EU would sanction any company helping Iran to build these massive ships. So if Iran doesn’t have control over the key parts of a ships supply chain, THEN DONT BUILD IT!
well when Iran Navy built Moudge Frigate they planned for a certain amount its not like you abandon certain ships when new ship design are prepared . this class of ships serve a purpose . when you built bigger ships they serve another purpose.
and we still don't have propulsion for bigger ships
Naval forces of Iran & Russia kick off joint drill in Indian Ocean
I hope we can to see Iran complete its bigger more advanced surface vessels so that future joint training excursuses will portray Iran's NAVY is much more 'modern' light so to say.

"Majid Bahmani, managing director of MAPNA Turbine Engineering and Manufacturing Company, a subsidiary of the group, told the same conference that the 2.2% increase in efficiency of third-generation MGT-70 turbine is a significant technological leap.
To put it into context, Siemens, one of the world's biggest turbine manufacturers, introduced an E-Class turbine in the early 1990s with 37% efficiency, but it took the company over two decades to enhance the number by 3%," he said."
