I put here this article from bmpd because it has a significant detail abou the domestic engines
The bmpd comment. In fact, it is a question of the project of equipping three unfinished frigates of the modified project 11356 with the all-mode main power plant as part of two gas turbine units, each of which will consist of two M70FRU gas turbine engines with a maximum capacity of 14 thousand hp each. Production of PJSC NPO Saturn. The total maximum power of the GEM will thus be 56,000 hp. (Maximum capacity of the full-scale project of the project 11356 - 60900 hp).
However, the main problem of this option is the development and manufacture of reducers for new gas turbine units, which can, in time, delay the completion of ships
They couldn't resist smearing some mental shit at the end. They claim the delay from designing the gear boxes is going to be longer than
from developing the gas-turbine engines. The clowns at bmpd need to get an education and quick. They make it sound like Russia
never built ship transmissions and gear assemblies, that Russia does not have the metallurgical capability. And that somehow a gas turbine
engine is a simpler device than a gear box. God, what an idiotic pile of Chicken Little excrement.
It is not simply "gear box".
It is a complicated transmission between the diesel engine, gas turbine and propeller.
"Simply" to connect a gas turbine to a generator require design that incorporation the turbine with the generator AND extensive testing and validation all three together.
One of the main problem is the vibration of the turbine / transmission / propeller / diesel engine.
Means that the turbine has a critical frequency (multiple actually) all component has one as well, and the system together has a sepratated critical frequency.
So, even if they manufacture a proto turbine ,reduction gear and propeller they still have to do extensive testing to prove that they won't destroy themselves and the ship.
Spare your pseudo-educated babble. A gas turbine engine is vastly more complex than any transmission.
Look at the vast complexity of standard gears, no turbine blade can come close...says the teenager. Who cares about
high temperature combustion.
According to the troll the device in the upper panel is more complex than the one on the bottom panel.
Russia doesn't make anything, it is a gas station with nukes, Obama and McCain are lords of truth for Singular_Transform:
