TÜMOSAN Shines at SAHA EXPO 2024 with High-Tech Diesel Engines and Power Systems
TÜMOSAN, one of the prominent brands in Türkiye's defense industry, garnered significant attention at SAHA EXPO 2024, held from October 22-26 at the Istanbul Expo Center, for its high-tech diesel engines and power systems.
Among the products showcased at TÜMOSAN’s booth were the ALP-1 (featuring the 8+1-speed TMSN 1308 AMT Transmission and TMSNX 5.4 Diesel Engine) and ALP-2 (featuring the 6+1-speed TMSN 2506 AT Transmission and TMSNX 7.4 Diesel Engine) Power Systems. Also on display were the TMSN 7.4 Marine Engine, delivered to the General Directorate of Shipyards and ARES Shipyard, and the PUSAT 4x4 Tactical Wheeled Armored Vehicle, equipped with the 310 hp, 1,000 Nm torque-capable TMSNX 5.4 Diesel Engine (exhibited with a cooling system; the engine is also available in a Marine Engine version with a capacity of 331 hp/232 kW). The booth also showcased an Independent Suspension System and TÜMOSAN’s next-generation Phase-5 emission-compliant engines developed for tractors.
Additionally, the ULAQ 12 ASuW Anti-Surface Warfare Unmanned Surface Vessel, developed under the SSB project through a partnership between ARES and METEKSAN, and powered by TÜMOSAN’s TMSN 7.4 Marine Engine and Power Group Control Unit, welcomed visitors at Ataköy Marina. Meanwhile, the ULAQ KAMA Expendable Unmanned Surface Vessel, also developed by METEKSAN Defense and ARES Shipyard, was showcased at the ARES booth during SAHA EXPO. Field tests for the TMSN 7.4 Marine Engine on the ULAQ SİDA platform are ongoing.
The 6-cylinder TMSNX 7.4 Diesel Engine, with a capacity of 460 hp (336 kW) and 1,600 Nm of torque, is available in both land and marine versions. The marine version (TMSN 7.4) produces 479 hp (352 kW) and 1,450 Nm of torque and is equipped with dual alternators. The land version was developed for FNSS Special Purpose Tactical Wheeled Armored Vehicles (ÖMTTZA), while the marine version is deployed in the ULAQ Project.
The TMSNX7 project, initially launched as a land vehicle engine development program, has been successfully adapted for marine applications. Through the marinization process, TÜMOSAN has produced and delivered engines to the General Directorate of Shipyards for use in push-and-pull vessels. In November 2020, two 6-cylinder TMSN marine engines were integrated into push-and-pull vessels used by the General Directorate of Shipyards. Following successful testing, TÜMOSAN signed a Strategic Cooperation Agreement with Gölcük Shipyard for the supply of these engines.
Additionally, TÜMOSAN successfully transitioned to mass production of its TMSN S8000 Mechanical Marine Engine, launched in 2020. This 4-cylinder engine, with a 3.9-liter displacement, delivers a maximum output of 105 hp at 2,300 rpm and 350 Nm of torque at 1,500 rpm. The S8000 series engines, primarily designed for tractors, have surpassed 269,000 units in production to date.
According to the information I have obtained, the qualification testing process for the 6-cylinder TMSNX 7.4 Diesel Engine, delivering 460 hp (336 kW) and 1,600 Nm of torque, and the TMSN 2500 AT Automatic Transmission (ALP-2 Power Pack) with a torque converter, 6 forward and 1 reverse gears, a maximum output of 650 hp, and 2,500 Nm of torque, is currently underway in both field and laboratory environments. These components are planned to be used on the PARS İZCİ 6x6 Wheeled Combat Armored Vehicles (WCAV) to be produced by FNSS under the ÖMTTZA Project.
The ongoing endurance tests at the TÜBİTAK Rail Transportation Technologies Institute (RUTE) laboratory aim to run the engine continuously for 1,000 hours. As part of the testing process, the engine is stopped every 100 hours for scheduled maintenance, including oil changes and filter replacements. By October 23, 800 hours of laboratory testing had been completed. TÜBİTAK is also making improvements to the test chamber and cooling system to support the tests. Once the 1,000-hour milestone is reached, the endurance tests requested by FNSS will be finalized, and the ALP-2 Power Pack will be installed on the vehicle for field testing as part of the verification process. Upon successful completion of these tests, TÜMOSAN will deliver the ALP-2 Power Pack to FNSS as a package for integration into ÖMTTZA platforms. According to TÜMOSAN, the power pack has achieved a local content rate of 95%.
In parallel with SSB Vehicle Projects, the development of the TMSN 2506 AT Fully Automatic Torque Converter Transmission has been ongoing at TÜMOSAN since 2017. The testing, qualification, and mass production preparation phases of the project have been planned and shared with SSB. Additionally, the TMSN 1308 AMT Electro-Hydraulic Transmission with Synchromesh is used on the PUSAT vehicle as the ALP-1 Power Pack with the TMSNX 5.4 Diesel Engine
