Development

The engine is developed for helicopters produced in Turkey. The "Turboshaft Engine Development Project" (Turkish: Turboşaft Motor Geliştirme Projesi, TMGP), launched on 7 March 2017, aims to reduce foreign dependency while increasing indigenousness rates.[3] The first installment of the TEI TS1400 is planned on the TAI T625 Gökbey, a twin-engined light transport/utility helicopter developed by Turkish Aerospace Industries. The engine was introduced to the public on 11 December 2020.[4] It was also announced that the engine may be used for T129 ATAK attack helicopter in the future.[5]
