TEI-PD170

TEI-PD170 is an aviation engine developed by TUSAŞ Motor Sanayii A.Ş. (TEI) with a turbo-diesel configuration. It was designed to meet Türkiye’s unmanned aerial vehicle (UAV) requirements and reduce external dependency. The engine stands out for its high power-to-weight ratio, extended endurance and high-altitude performance. Studies published by TÜBA also regard the TEI-PD170 as a critical example among Türkiye’s indigenous aviation engines.

The engine was developed as part of Türkiye’s objective to produce a national solution for UAV engines. It was conceived in line with TEI’s experience in turbo-diesel engine development and the state’s national technology policies. As reported by AA News, the development of the PD170 took into account the requirements for long endurance and high-altitude operations. The entire design, testing and production process of the engine was carried out using domestic capabilities.

The TEI-PD170 is a four-stroke, liquid-cooled, turbo-diesel engine producing 170 horsepower. It is capable of operating on both Jet-A1 and JP-8 fuels. Thanks to its twin-turbocharging system, power loss at high altitudes is minimized. Designed to operate effectively at approximately 40,000 feet (12,000 meters), the engine ensures high efficiency and reliability during extended missions.

The engine is primarily used in Türkiye’s leading UAV platforms, ANKA and AKSUNGUR. Its high energy density and extended endurance enhance the operational capabilities of UAVs. As a nationally produced system, it enables the management of maintenance, spare parts and logistics within the country, thereby reducing external dependency.

The TEI-PD170 stands as a symbol of Türkiye’s capability to develop its own aviation engines. The engine’s success has been demonstrated through long-endurance flight records, such as a 35-hour continuous flight, highlighting both TEI’s engineering capacity and Türkiye’s progress in engine technology. The strategic advantages provided by national production have filled a critical gap in Türkiye’s defense industry.
