It was designed for use in Turkish unmanned aerial vehicles (UAVs) and serves as a core part of Turkey's indigenous aerospace engine initiatives.
The engine delivers a maximum power of 170 hp (127 kW) and is optimized for high altitude and endurance performance.
[1] The TEI-PD170 program began in response to Turkey's need for a domestically produced engine for its UAV platforms, reducing reliance on foreign suppliers.
The engine is notable for its fuel efficiency, high-altitude capability, and modular design, making it ideal for long-endurance missions.
A higher-powered variant, the TEI-PD222ST, is under development to meet increasing performance requirements.
