We generally develop and introduce very similar systems. We have deep and strong relations, and I see no reason for that to change in the foreseeable future. One of my biggest hopes is that one day we can work on the same projects as partners, developing them faster and at a better cost. We would create an enormous synergy... something that other countries would look at in awe!

Can you see any possible partnership projects in the near future?

Can you see any possible partnership projects in the near future?

There’s definitely a lot of potential, but since we haven’t really seen major joint projects, it’s reasonable to keep expectations low.
Still, in an ideal world, cooperation could absolutely happen in areas like satellites, space and aerospace projects, laser weapon systems, turbine engines, and even SMRs (Small Modular Reactors).
The technological profiles of both countries actually complement each other well, yet it just requires strong political will, long-term planning, and mutual trust to turn that potential into reality.

Doosan Enerbility is accelerating its push into the North American market after securing an additional gas turbine order in the United States.

The company announced on December 17 that it has signed a contract with a U.S.-based big tech company to supply three 380-megawatt-class gas turbines. In line with the customer’s data center construction project, Doosan Enerbility will deliver one gas turbine and one generator in 2027, followed by two gas turbines and two generators in 2028.

The latest deal follows a previous contract signed in October for the supply of two gas turbines, bringing the total number of gas turbines ordered by the same U.S. big tech company to five within approximately two months.

Doosan Enerbility attributed its rapid increase in gas turbine orders in the U.S. market to its proven product performance, fast delivery capabilities, and stable after-sales support provided through its local subsidiary. Since achieving localization of large-scale gas turbines in 2019, the company has accumulated more than 17,000 hours of demonstration operations, establishing strong technological credibility. Including the latest contract, Doosan Enerbility has now secured orders for a total of 12 gas turbines, further demonstrating its competitiveness in the global market. The maintenance and service capabilities of its Houston-based subsidiary, Doosan Turbomachinery Services (DTS), have also played a key role in expanding U.S. orders.

Son Seung-woo, Head of the Power Service Business Group at Doosan Enerbility, said that following its first overseas export, the company’s success in securing additional contracts has helped solidify its presence in the global gas turbine market. He added that Doosan Enerbility will continue to strengthen its competitiveness in the rapidly growing North American market and proactively respond to rising demand.

Hanwha Emerges As Re-Engine Option For Lockheed Vectis | Aviation Week Network

A Hanwha turbofan engine scheduled for completion in 2028 is a candidate to re-engine the Lockheed Martin Vectis, a CCA designed by Skunk Works.

aviationweek.com

It was actually mentioned in an article in Aviation Week last year. The report mentioned that Lockheed Martin was considering the HAF4500 engine for its CCA. The reasoning was that, given the limitations of the current FJ44-4A engine, the HAF4500 would offer the advantages of higher operational availability, increased thrust, and a faster top speed. However, since the engine hasn’t even been unveiled yet, I had been dismissing the idea.

According to attendees at the recent conference held by The Korean Society for Aeronautical and Space Sciences, they were able to see firsthand that significant technological advancements have been made and that development is now well underway.

The most notable feature of the HAF4500 is that, unlike the 5,500-pound-class turbofan engine currently under development and other high-bypass engines, it incorporates Integrated Starter Generator (ISG) technology. This enables it to provide 100 kW of electrical power, making it easier to install high-power radar systems and electronic warfare defense equipment. The engine core is based on that of the KTP1400 turboprop engine.

It could be said to be similar to the CCA engine being developed by Rolls-Royce and ITP Aero.

The KUH-1 Surion series helicopters currently primarily used in South Korea are developed based on the Eurocopter AS532 Cougar as their original design. However, while the original model was equipped with the Makila engine, the Surion had its engine changed to the T-700 series engine used in the Black Hawk.

However, because the engine was not properly compatible with Airbus's existing power transmission system, resulting in reduced output, the military signed a contract with KAI in 2021 for a project to upgrade and localize the power transmission system.

Previously, SNT Heavy Industries attempted to develop the main gearbox but failed, leading to full reliance on foreign imports. KAI has selected Italy's Avio Aero as a partner for joint development. The intellectual property rights for the main gearbox following this joint development will belong to South Korea.

Through this upgrade, the input-to-output speed reduction ratio of the KUH-1 Surion main gearbox will increase from the existing 4:1 to 5:1, leading to an overall 25% increase in speed. The existing French-imported gearbox limits the power output to 19,200 pounds.

However, the domestic production of the gearbox will enable the T700-701K engine output to be increased to 22,000 pounds.

The project is being conducted in a total of three phases, which are as follows:

The assembly and initial test run of the main gearbox prototype have been completed. This has confirmed that it can be successfully integrated into the KUH system. It will now undergo evaluation to test targets for a 27% increase in power output, a 15% increase in maximum takeoff weight, and a 100% improvement in maintenance intervals and service life by 2028.
