In line with its efforts to end Turkey's external dependence on engines, TEI developed 12 national and 1 domestic engine in a period of approximately 10 years. Flights were made with 7 of these engines, and mass production of 6 engines started.
TEI produced the TEI-TJ90 turbojet UAV engine for the high-speed target aircraft ŞİMŞEK in 2014, the TEI-PG115 gasoline UAV engine in 2015, the TEI-PD155 diesel UAV engine for ANKA in 2016, and the TEI-PD170 diesel for ANKA SİHA in 2017. It operated the TEI-TS1200 core engine for the UAV and GÖKBEY helicopter, the T700-TEI-701D for the T70 Black Hawk helicopter in 2018, the TEI-PG50 and also the TEI-PD222-DT engine for the kamikaze UAV KARGI in 2019.
In 2020, it managed to operate TEI-PD180ST and TEI-TS1400 engines, as well as the TEI-TJ300 engine, for medium-range anti-ship missiles, and TEI-PD222ST engines in 2021.
TEI last operated Turkey's first military turbofan engine, TEI-TF6000, in March 2024. TEI-TF6000, which will power the unmanned warplanes KIZILELMA and ANKA-III, will pave the way for the engine of the national combat aircraft KAAN.
TEI managed to fly with the platforms where these engines TEI-TJ90, TEI-PG115, TEI-PD155, TEI-PD170, T700-TEI-701D, TEI-PG50, TEI-TS1400 will be used.
Mass production started for TEI-TJ90, TEI-PG115, TEI-PD155, TEI-PD170, T700-TEI-701D, TEI-PG50 engines.
As a result of the work carried out to develop Turkey's first domestic and national aviation engine that will meet the power needs of medium-altitude long-endurance UAVs, especially ANKA, the TEI-PD170 turbodiesel aviation engine emerged.
TEI-PD170, which is ahead of its competitors in terms of altitude capabilities, weight and fuel consumption, has a ceiling altitude of 45 thousand feet.
TEI-PD170 engine, which has reached the mass production stage after 8000 hours of calibration and testing activities, has been integrated into ANKA and AKSUNGUR and is performing flight tests with Bayraktar TB3, which it carried into the sky for the first time.
TEI developed Turkey's first national helicopter engine TEI-TS1400 for the general purpose helicopter GÖKBEY. TEI has achieved many firsts in the fields of manufacturing and material technologies in the production of the engine with a power generation capacity of up to 1660 horsepower. The company, which produced the first single crystal turbine blade in Turkey, developed aviation quality forging technology for nickel and titanium alloys for the first time. TEI-TS1400, which made a successful flight test with the GÖKBEY helicopter, will start to power national helicopters after development, flight tests and mass production studies.
TEI-TJ90 Turbojet Engine, developed by TEI for target aircraft and producing 400 newtons of power, successfully completed its first flight with the Turkish Aerospace Industry's ŞİMŞEK platform in 2017.
Developed with the support of TÃœBÄ°TAK, TEI-PG50 is Turkey's first two-stroke aviation engine. The engine, produced for UAVs under 300 kilograms, draws attention with its 50 horsepower take-off power and 30 horsepower at an altitude of 16 thousand feet. The TEI-PG50 engine, which offers more power and a higher power/weight ratio than rival UAV engines used in its class, made its first flight in May 2019.
Turkey's first medium-range anti-ship missile engine, TEI-TJ300, was designed and produced with domestic and national resources. The engine, which weighs less than 30 kilograms and has a narrow diameter of 24 centimeters, is the first turbojet engine in the world that can produce 1300 newtons of thrust in its thrust class. TEI-TJ300 produces nearly 400 horsepower at speeds reaching 90 percent of the speed of sound
