In my ignorance: setting politics aside, which could preclude co-developments

(estimated)

1 How long for Turkiye to develop TF35000 alone?
2 How long for ROK to develop an engine for Kf-21 alone?

Could time be saved through the 2 countries sharing technology? I guess that there must be areas in which one country is ahead and other areas where the other country is ahead.
Two chefs in a kitchen wouldn't shorten the development time. Besides, the power outputs of the engines are not similar.

Current KF-21 is a bit small for it to have an IWB. Maybe a larger version in the future could require TF35K level of thrust and the Koreans could become interested in the Turkish made engine.

But that's way into the future. First we need to see some progress regarding TF35K.

I was not suggesting amalgamating the 2 engines. I was curious if Turkiye and ROK might gain something by exploiting each other's R&D and differing know how.

I'm not sure if that question could be answered by forum members. Turkish defense publications are very vocal about the developed capabilities but they're tight-lipped when it comes to the weaknesses. You could make some broad brush statements like we're lacking in serial production but that would be too general to be helpful. I'm guessing the same secrecy applies to Korean projects as well.

Doosan Enerbility capabilities and straegies for aero engine development

Doosan has already made significant achievements in the field of gas turbines for power generation and that it has faithfully equipped related testing facilities. Of course, Doosan fully recognized the difference between aviation gas turbines and power generation gas turbines and said it would use its experience for development.

Currently, the license-produced F-414 for KF-21 is said to have a localization rate of 39%. (based on mass production unit 1)


DAPA is thinking of a plan in which Hanwha and Doosan, and furthermore, Korean companies and university research institutes all participate, rather than a single company monopolizing it. This is because aviation engines require a one-team team for Korea to advance into this difficult and new field. In addition, there is a plan to include foreign companies, which will announce a detailed roadmap at the end of November.

When will Block 3 available to international market?
If Korean can't deliver it fast, China will dominate that "5th gen for non US allies / partners" with J35A for sure.
Well? I'm not an expert, I'm not a policymaker, so I don't think I can say exactly. If the J-35 is going to dominate the market, I think it's better to do so. That's... the U.S. is going to take care of it. HA HA.

Doosan Enerbility Succeeds in Performance Test of 380MW Gas Turbine​

142082_91093_302.jpg

Doosan Enerbility has successfully completed performance testing of its independently developed 380MW gas turbine. The company plans to intensify its efforts to penetrate overseas export markets with this gas turbine, which also meets global environmental regulation standards.

Doosan Enerbility announced on June 5 that its 380MW gas turbine model has successfully passed the rated load performance test.

The rated load performance test is a final inspection process where the fully assembled gas turbine is operated at maximum speed and output under conditions identical to those in an actual power plant to verify its performance and stability.

This performance test was conducted over three months from February at the dedicated gas turbine test facility established at the company’s headquarters in Changwon, South Gyeongsang Province. Through the performance test, various operational indicators including output, efficiency, vibration, temperature, and exhaust gas were comprehensively examined. In particular, the test also included operational flexibility checks for power supply to data centers and rapid start-up tests to complement the intermittency of renewable energy generation.

The gas turbine that successfully passed this performance test is a 380MW model. This model boasts output and efficiency levels comparable to those of global leading companies. When operated in combined cycle, it can achieve an output of 570MW and an efficiency of 63%. As it also meets global environmental regulation standards, it is evaluated as a product capable of full-scale entry into overseas markets. Combined cycle power generation is a method that produces electricity twice by using high-temperature exhaust gas from the gas turbine to boil water, create steam, and then operate a steam turbine with this steam.

Jeong Yeon-in, vice chairman of Doosan Enerbility, stated, “The successful rated load performance test of this 380MW model has laid the foundation for full-scale competition in the global market. As a favorable atmosphere is rapidly forming in the gas turbine business recently, we will actively strive to strengthen Doosan’s gas turbine position in the global market.”

Korea Southern Power Co. started commercializing its core parts of the 7F gas turbine installed at the Busan Complex Power Plant on the 1st.

According to Southern Power on the 3rd, the core parts of the gas turbine installed this time are the first gas turbine rotors (rotation shafts) that Doosan Energy has refurbished using domestic technology for the first time in Korea and high-temperature domestic gas turbine parts researched and developed as a national project.

Since it is the first time for Southern Power to install and operate domestic core parts at the same time, the commissioning was carried out in accordance with the procedures carried out when constructing new complex power plants to ensure soundness. It also plans to continue commercial operation throughout the life cycle of parts and check long-term stability.

Automated guided vehicles (AGVs) transported necessary materials and items from the warehouse to the equipment, where robotic arms loaded the parts into the machinery to manufacture them. Human workers only performed visual inspections when required.

Employees can monitor the process in real time. The factory operates 24 hours a day. Jo Woon-rae, Manager of the Engine Production Team at Hanwha Aerospace, expressed pride in the components produced by Hanwha Aerospace, stating, “There is a saying that ‘there is no commercial aircraft currently in operation that does not have a Hanwha Aerospace component.’”

Doosan Enerbility announced on the 13th that it had signed a contract to supply two 380-megawatt (MW) gas turbines to a major US tech company by the end of next year. The contract partner and scale were not disclosed at the request of the client.(Other media sources mentioned that it is being supplied to the data center of Musk's AI company, xAI.)

Doosan Enerbility succeeded in localizing large gas turbines for power generation in 2019 in collaboration with Korean industry, academia, and research institutions, securing gas turbine technology as the fifth country in the world after the US, Germany, Japan, and Italy. Subsequently, the performance was proven through successful demonstration for 15,000 hours at the Gimpo Combined Heat and Power Plant. Including this contract, the company has signed a total of eight gas turbine supply contracts in a row. Up until now, it had been supplying gas turbines mainly to domestic power plants, such as Korea Western Power.

The soaring demand for power from data centers in the era of Artificial Intelligence (AI) has also created an opportunity for Doosan Enerbility. Data centers worldwide are finding it difficult to meet their demand through existing power grids and are seeking their own power supply solutions. Gas turbines are drawing attention due to their advantages in terms of construction period, supply stability, operating period, and efficiency. According to S&P Global Commodity Insights, the global gas-fired power generation market (based on cumulative installation) is projected to grow from 2,067 gigawatts (GW) last year to 2,712 GW by 2040.

The existing global gas turbine market was dominated by a three-way competition between the US's General Electric (GE), Germany's Siemens, and Japan's Mitsubishi Hitachi Power Systems (MHPS). However, as demand increases, latecomer Doosan Enerbility is now also able to target new markets. An industry official stated, "Doosan Enerbility has jumped into the gas turbine market, which used to be supplier-centric, and is now actively competing by focusing not only on price competitiveness but also on service convenience."

For gas turbines, the importance of services, such as maintenance and repair, is significant, not just new supply. Doosan Enerbility plans to accelerate its penetration into the US market through synergy with its gas turbine service specialized subsidiary, DTS, located in Houston, US. DTS will perform the maintenance services for the gas turbines supplied to the US market in the future. Son Seung-woo, head of Doosan Enerbility's Power Service BG, said, "This contract is a meaningful turning point for South Korea, as it transitions from a gas turbine importing country to an exporting country," adding, "We will repay the customer's trust by strictly adhering to quality and delivery deadlines, and further expand into overseas markets like the US."
