In the latest endurance tests, the TUSAS Engine Industry’s (TEI) TS1400 turboshaft engine reached 1740 shp emergency power, setting a new record. Within the scope of EASA certification, TS1400 has completed EASA CS-E 740, an endurance test involving six hours of wear-down 15 times consecutively.
Following the endurance test, the engine was tested in a one-engine inoperative scenario where the helicopter needed to be able to make an emergency landing on one engine. In the emergency test, Turkiye’s first Indigenous turboshaft engine reached 1740 shp emergency power, previously stated as 1660 shp. TS1400’s continuous power rating is 1400 shp, which is also likely to increase over time, like the emergency power.
These tests are needed to prove that TS1400 is serviceable under continuous operation and one engine can safely land the helicopter it will serve in the TUSAŞ T625 GÖKBEY utility helicopter. Even though the engine is mainly intended for civilian helicopters like T625 GÖKBEY, it can be adapted for military ones like the T129 ATAK attack helicopter and the future T629 attack helicopter to succeed T129.
