ANKARA, Turkey — Turkey's procurement agency has commissioned a local company to develop critical technologies for an engine that the government hopes will power its first indigenous fighter jet.
A contract was signed Feb. 14 between two state-controlled companies for the development program. Under the deal, TRMotor, an engine maker, will develop an auxiliary power unit and an air turbine start system for what Turkey hopes will be critical components of an indigenous engine to power the TF-X aircraft.
TRMotor signed the deal with the prime contractor of the TF-X program, Turkish Aerospace Industries, another state-controlled defense company.
“The program aims to develop critical technologies ... that will enable us [to] possess indigenous engines,” said Osman Dur, general manager of TRMotor. “The [indigenous] TF-X engine is at the moment at its concept design phase.”
TRMotor is completely owned by SSTEK A.S., a defense technologies company owned by Turkey's defense procurement agency, the Presidency of Defense Industries, or SSB.
This is a milestone contract for the TF-X program,” said TAI CEO Temel Kotil.
The deal comes as SSB is holding talks to co-produce an engine with a consortium of the British company Rolls-Royce and Turkish firm Kale Group.
In 2017, Kale Group and Rolls-Royce launched a joint venture to develop aircraft engines for Turkey, initially targeting the TF-X. But the £100 million (U.S. $139 million) deal was effectively put on hold due to uncertainties over technology transfer.
A year before the partnership, TAI signed a $125 million heads of agreement with BAE Systems to collaborate on the first development phase of the TF-X. Turkey originally planned to fly the TF-X in 2023, but aerospace officials put off the target date to the 2025-2026 time frame.
The TF-X program, or MMU in its Turkish acronym, has been crawling over the past years due to technological failures and know-how transfer. Turkish engineers must first select an engine for the planned aircraft before they finalize their designing phase.

Le constructeur suédois Saab est parvenu, pour la première fois, à faire voler un avion équipé d'une pièce extérieure imprimée en 3D. L'avionneur utilise la technologie de la fabrication additive depuis quatre ans, notamment pour imprimer des pièces internes, précise L'Usine Nouvelle. La pièce, une trappe située sur le flanc arrière du fuselage de l'appareil, un modèle Gripen, a été imprimée sur la base du scan de la pièce originelle. Parfaitement ajustée à l'avion, elle n'a montré « aucun changement structurel visible après le vol d'essai », assure Hakan Stake, responsable du projet, dans un communiqué. Cette démonstration devrait, à terme, « permettre au personnel sur le terrain d'avoir accès à des pièces de rechange ajustées individuellement, d'éviter les réparations d'urgence ou de cannibaliser un appareil déjà endommagé », souligne-t-il. Il estime par ailleurs que cette solution permettra de réduire le nombre de pièces transportées lors du déploiement d'un appareil et de réduire son temps de réparation. De nombreuses étapes de certification du matériau utilisé, un polyamide 2200, couramment utilisé dans la fabrication additive, sont encore nécessaires avant de déployer la technologie sur le terrain.
