TEI TS1400
The TEI TS1400 is a 1,400 shp turboshaft engine for rotary wing applications. It is developed by the Tusaş Engine Industries (TEI) in Turkey.[1][2][3]
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 to use the engine on the T129 ATAK attack helicopter.[5]
