Preparing for a 9,000-ton general-purpose destroyer? Military media: The 052D "Baotou" destroyer has replaced the new generation of gas turbines!
Wow, I didn't expect that our navy's 052D destroyers and China Shipbuilding 703 Research Institute have quietly done a big thing in recent years. Recently, according to the latest report from "PLA Daily": two years ago, the 052D destroyer "Baotou" was equipped with the latest domestically produced gas turbine, completing the update of the gas turbine.
By the way, this year is 2024, and the 052D "Baotou" was launched in May 2019, which means that the ship was retrofitted with the "new generation gas turbine" during its construction. Previously, the power system of the 052D series used two GT-25000/CGT-25M gas turbines plus two MTU-20 diesel engines. Therefore, this "new generation gas turbine" is most likely CGT-30M.
The rated maximum power of CGT-25M is about 25-28 megawatts, while CGT-30M is a product developed by China Shipbuilding 703 Research Institute that comprehensively matches the American LM2500+ gas turbine. This type of gas turbine has a maximum rated power of about 33.5 megawatts and a thermal efficiency of 39.3%, with performance that is almost superior to LM2500+. Overall, its performance is quite good.
Moreover, since the built 052D destroyers can directly replace CGT-30M, it indicates that the size of this gas turbine has not changed much compared to CGT-25M. The act of the 052D "Baotou" retrofitting CGT-30M clearly aims to test the new generation of gas turbines on an established platform, preparing for the large-scale use and improvement of this power system in the future, such as applying it to the long-awaited new 9,000-ton general-purpose destroyer.
Referring to the current CODOG (combined diesel and gas) power configuration and structure of the 052D destroyers, if the new general-purpose destroyer also uses two CGT-30M gas turbines and two diesel engines for combined diesel and gas propulsion, it will be sufficient to meet the power demand of an 8,500-ton-class destroyer; if it changes to CODAG (combined diesel and gas) or full electric propulsion, it would easily meet the power requirements of a 9,500-ton-class destroyer.
Of course, many military fans believe that the new 9,000-ton general-purpose destroyer may directly adopt two 40-megawatt class CGT-40M gas turbines as the power system, but personally I am more inclined towards using two CGT-30M gas turbines plus two diesel engines with full electric propulsion or combined diesel and gas propulsion...
