New information has been shared about the TEI-TS1400 engine developed by TUSAŞ Motor Industry AŞ (TEI). TEI General Manager and Chairman of the Board Mahmut Faruk Akşit announced that the manned flight tests of the TEI-TS1400 engine will take place in 2023.
The power value tests of the TEI-TS1400 engine, which will power the T625 GÖKBEY Utility Helicopter, which will be integrated into Gökbey
developed with national resources, are continuing. In the coming days, tests at higher and more demanding power values will be completed and an application for permission for manned flights will be made to the General Directorate of Civil Aviation.
Statement from Temel Kotil about the National Combat Aircraft
Announcing that they aim to carry out manned tests in 2023, TEI General Manager Faruk Akşit said, “Our engine currently produces the maximum continuous power to lift our helicopter. Our goal is for the TEI-TS1400 engine to pass all the tests successfully in 2023 and receive the manned flight certificate from the General Directorate of Civil Aviation. Later, manned flight tests will be carried out. We aim to achieve manned flight in our national helicopter before the end of 2023.” said.
One of the most critical subsystems of helicopter engines is the gearbox. The gearbox of TEI-TS1400 was produced with national means in cooperation with TEI and Alp Aviation. In the first trials with the shaft gearbox, the maximum continuous power cycle of the engine was successfully achieved.
Stating that the original and locally developed gearbox is in international quality standards, Akşit concluded his words as follows:
“With the first shaft gearbox “We have reached the maximum continuous power speed of our first national helicopter engine. It is very important to achieve this in the first attempt with the gearbox produced for the first time. With the localized accessories in the TEI-TS1400 engine, we have reached the maximum output speed of 23 thousand rpm and exceeded the maximum continuous power of 1400 horsepower.”
