Korea Ground Heavy-Duty Drivetrain

[Windchime]

This thread will serve as a general thread about Korean heavy-duty reciprocating engines products and programs, both for civilian and military, ranging from trivial electric motors, high-speed to low-speed diesel engines for trucks, armored vehicles and ships, to future electric drives and alternative fuel engine programs.

SMV1360 replacing MB 871 has been developed and SMV1000 replacing MT 881 is under developmet and is scheduled to be completed by mid 2020s. Concrete plans for the application of these engines replacing the German origin engines in K1 and K9 variants are currently undecided.

SMV1360 will most likely will be included in the K1A3/K1E2 upgrade program scheduled for mid-late 2020s following major overhaul. This is also due to operational support related problems regarding the parts supply of the MB 871 engine which is a fairly old model today.

Since K9s in Korean Army service are relatively new, it is unlikely that MT 881s inside them will be outright replaced in the short term. Current focus of SMV1000 program is to offer alternative engine for the export customers in the ME and elsewhere, such as UAE, which the export deal was blocked by the German embargo.

Underlying technologies for future AFV drivetrain/powertrain are under development. These are hybrid drive and hydrogen PEM fuel cell driven electric powertrain.

K-2전차 4차양산용 변속기 시험 새제품으로 장착 결정

방위사업청이 K2전차에 국산 변속기 적용을 검토하기로 결정했지만 새 국산변속기로 테스트하는 것으로 잠정 결정했다. 기존 제품이 아닌 새 변속기를 만들어 시험평가에 참여하라고 업체에게 통보를 한것으로 알려졌다.6월 11일에 방위사업청·국방기술품질원과 SNT다이내믹스 등이 참여한 회의에서 K2전차 4차 양산분에 국산 변속기를 탑재하기 위한 시험평가 방안이 논의됐다.방위사업청은 변속장치, 제동장치 국산화 및 강건 설계 반영 등 품질개선이 이뤄졌다는 판단에 따라 이번 4차 양산 사업을 추진하면서 국산 변속기를 탑재한다는 계획이다. 국산 변

The SMV-1000 was announced at the 2023 KOREA INDUSTRIAL TECHNOLOGY R&D EXPO on December 6-8. Mass production is expected to begin in 2024.

-Localization of 1,000 horsepower engine parts for K9 self-propelled howitzer
-STX engine / Katech, Hanyang University, Hanwha Aerospace
-Summary : • Successfully developed indigenous engine to lift export restrictions on K9 self-propelled howitzers to Egypt, UAE, Poland, etc.
- •Signed a contract to export 337 domestic engines to Egypt (KRW 134.8 billion) and expanded the market (KRW 168 billion)
•Achieving world-class technology for 1,000-horsepower engine basic performance and core components
•The K9 engine performance evaluation developed this time allows you to check engine performance equal to or higher than that of the MTU
•335 units will be exported to Egypt through full-scale mass production from 2024 after the release of the first and second units in July, 2023

SMV-1000

One of the biggest advantages of the SMV-1000 mentioned in the video is the ability to replace the K-9's engine (MTU MT 881) without changing the system equipment.

SMV-1000 First Engine Release Ceremony

In 2020, the DAPA and the Ministry of Trade, Industry and Energy signed an MOU on technical cooperation to localize core materials and parts of the defense industry (in September). Since April 2021, the development of the K9 self-propelled gun domestic engine has begun, and a total of 32.1 billion won, including 22.8 billion won in state funds, has been invested, and in three years, about 500 engine core components have been localized and mass-produced. It is expected that the K9 self-propelled gun will further expand into the global market in the future as its domestic engine has improved performance and economy compared to the existing engine and has its own export capability.

The first mass-produced power pack for export to Turkiye was delivered in April last year, and the power pack under test in the article is the second mass-produced power pack. Unit 3 is in the works at another plant. It takes more than six months to make a single transmission, but once a large-scale mass production system is in place, it is said that a transmission can be made every three days. SNT Dynamics is planning to set up two transmission production facilities to meet the initial volume of Altay tanks.

Hanwha Aerospace announced on Wednesday that it has recently successfully completed the durability test of the K9 self-propelled howitzer 's domestic engine, which was conducted from the second half of 2023 to December last year. The engine was tested for 10,000 kilometers in various driving environments, including deserts and mountains, at home and abroad, including Middle Eastern countries such as Egypt, and met all technical and operational requirements for performance and maximum power.

Accordingly, the K9 self-propelled howitzer with a domestically produced heart will be mass-produced in Egypt from the second half of this year(I saw a press article that said December.).
In February 2022, HANHWA Aerospace signed a contract with the Egyptian government to export a package worth 2 trillion won, including the K9 self-propelled artillery gun, K10 ARV, and K11 FDCV.

To integrate the newly developed indigenous engine into the existing K9 system, veteran pilots have been driving the vehicle for over a year. Each day, four pilots took turns driving 100 kilometers.
