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.

## 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. 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. It was also announced that the engine may be used for T129 ATAK attack helicopter in the future.
