Developed by TEI to power the local GÖKBEY general-purpose helicopter and T129 ATAK attack helicopters, TS-1400 was first run in October 2020.

Speaking at the “CAREER AND PROJECTS AT TEI” event held on December 3, 2020, TEI General Manager Mahmut F. AKŞİT reminded that the contract for the TS1400 engine was signed in February 2017, and the engine was first ignited in January 2020,
“In this year on October 22, we successfully started our engine (TS1400) as a complete helicopter engine, that is, including the power turbine to turn the propeller of the helicopter. We have completed the minor deficiencies including accessories since October 22.”
TEI continues its efforts to complete the engine for GÖKBEY first general-purpose helicopter to be produced. Akşit stated that they had developed a powerful engine and said that the TS-1400 engine produced 100-150 more horsepower than the engine (LHTEC-CTS800-400A, 2 1014 kW) used in GÖKBEY’s tests and currently powering our T129 ATAK attack helicopters.
