Turbine blades, whose advanced technology surface coating processes were successfully completed by TÜBİTAK MAM, were delivered to TEI with a ceremony held at the SAHA 2026 Fair, which brought together the giants of the defense industry.
In line with Turkey's domestic production targets in the defense and aerospace industry, an important cooperation that will contribute to indigenous engine technologies has resulted in a concrete success. The fixed steering vanes (NGV) produced by TAI Motor Sanayii A.Ş. (TEI) and included in the national turboshaft engine TEI-TS1400 were delivered at the SAHA 2026 Fair after the processes completed at TÜBİTAK Marmara Research Center (MAM) laboratories.
Thermal Barrier Coating
TÜBİTAK MAM High Temperature Materials Research, Development and Repair Center of Excellence, under the Vice Presidency of Materials and Process Technologies, has ensured that parts gain resistance against high temperatures. To this end, a thermal barrier coating was applied to the blade surfaces using a special technique, Electron Beam Physical Vaporization (EB-PVD). These components, which will serve in the hottest part of the engine, will contribute to increasing their service life and maximizing engine efficiency by gaining high thermal insulation properties with the thermal barrier coating applied.
The handover ceremony, which took place at the fairgrounds, brought together representatives of the sector and the institutional protocol. The ceremony was attended by Mehmet Fatih Kacır, Minister of Industry and Technology; Prof. Dr. Orhan Aydın, President of TÜBİTAK; Prof. Dr. Burcu Özsoy, President of TÜBİTAK MAM; and Mahmut F. Akşit, Chairman and General Manager of TEI.
Drawing attention to the importance of the technology delivered at the ceremony, Prof. Dr. Burcu Özsoy said the following:
“The original parts we are delivering to our GÖKBEY helicopter as the final product by TÜBİTAK MAM actually constitute the most critical part of the propulsion systems in the engine combustion chamber, and the main technology here is represented by thermal barrier systems. We are pleased to present these original parts developed within our center.”
Mahmut F. Akşit, General Manager of TEI, evaluated the function and production model of the delivered components, and drew attention to the operational dimension of the cooperation with the following statements
“This product we have received is the application of advanced thermal barrier, heat reduction and insulation technologies to real turbine blades. While TÜBİTAK MAM develops the process in this cooperation, we, as TEI, carry out the serial production. We would like to thank our Minister of Industry and Technology and TÜBİTAK executives for their contribution and support to the process.”
Within the scope of the ceremony, the delegation also examined the final stage of the “Single Crystal Turbine Blade” technology, another important work of the center.
Acting with the goal of fully independent aviation, TÜBİTAK MAM and TEI aim to continue their joint projects in the fields of aviation and defense with determination.
