The first batch of 4 T700-TEI-701D turboshaft engines to be used on T70 Utility Helicopter Platforms and produced within the scope of the Utility Helicopter Program, which is being conducted under the responsibility of the Presidency of Defence Industries (SSB) and the main contractor of the engine, TEI ,were delivered to Turkish Aerospace at a ceremony where President of Defence Industries Prof. İsmail DEMİR, Eskişehir Governor Özdemir ÇAKACAK and a large number of guests were in attendance.

The TEI-701D-T700 turboshaft engine to be produced by TEI will be a new milestone in Turkey’s national aerospace history because it is the first helicopter engine to be produced in Turkey.

Considering the 30-year life span of T700-TEI-701D engines to be used on the T70 platform, it is aimed that TEI will make significant contributions for providing services in the fields of maintenance, repair, overhaul, training, technical support as well as supplying spare parts to domestic and foreign end users.

TEI will be able to provide maintenance, repair, overhaul, training, and technical support services to the T700 family of engines in more than 20 countries in Europe, Middle East and Asia within the scope of this project.   

Future projections indicate that if the T70 helicopter is procured abroad and if the customer selects the T700-TEI-701D engine produced under license by TEI, these engines can be exported abroad.

In the serial production phase which is expected to launch between 2020 and 2025, a total of 248 T700-TEI-701D engines (236 committed and 12 optional) will be produced.  Within the program the objective is also to achieve the capacity to produce 1 engine per week in the later stage of the serial production phase.

Groundbreaking Ceremony held for the Construction of the Turboshaft Test Center Building (Phase-2) Project 

During the event, the groundbreaking ceremony for the construction of the Turboshaft Test Center buildings was also held. TEI will produce a 1400 shp domestic and national turboshaft engine that will power the T625 GÖKBEY 6 Ton Utility Helicopter in line with the project initiated by the Presidency of Defence Industries signed on February 7, 2017 in order to meet the engine requirements of the helicopter developed for the Turkish Land Forces Command.

While the core engine designed by TEI runs stably at 28,000 RPM, during the project great progress has been achieved in understanding the engine’s constant operation speed and idle speed.

The Turboshaft Test Center will have an area of 30,000 m2 with 19 different test rooms as well as workshops and offices with a 500 personnel capacity. With the launch of the building, the need for the TEI-TS1400 engine’s overseas testing will be reduced, and with the development of domestic testing capability, the aim is also to reduce foreign dependency. With the activation of this facility, the tests for similar class engine projects to be developed will be completed and commissioned quickly and efficiently.
