The TEI-PD200 is a turbodiesel aircraft engine developed by TUSAŞ Engine Industries (TEI) in Turkey. It is part of the PD-series engine family and represents a higher-power derivative of the TEI-PD170, intended for medium-altitude long-endurance (MALE) unmanned aerial vehicles (UAVs).[1]
Design and development
The PD200 was developed as an evolutionary upgrade to the PD170 engine to meet increasing power requirements for heavier UAV platforms. According to industry sources, the engine produces approximately 197 horsepower and retains a similar 2.1-litre inline-four turbodiesel architecture as its predecessor, while incorporating modifications to improve altitude performance and endurance.[2][3]
Publicly available technical documentation indicates that the engine is designed for high-altitude UAV operations and features a two-stage turbocharging system, redundant electronic engine control, and compatibility with aviation fuels such as Jet-A1 and JP-series fuels.[4]
Operational history
The PD200 has been reported as undergoing flight testing on Turkish UAV platforms, including the Bayraktar TB3, a carrier-capable unmanned combat aerial vehicle developed by Baykar. However, detailed operational deployment status has not been officially disclosed in open-source government publications.[5]
Design characteristics
According to manufacturer and defence industry sources, the PD200 retains a similar configuration to the PD170 family:
- Inline four-cylinder turbodiesel architecture
- Liquid-cooled design
- Common rail direct fuel injection
- Two-stage turbocharging system
- Redundant electronic engine control system (FADEC-class architecture)[6]
The engine is designed for operation at high altitudes, with reported service ceiling capabilities up to approximately 45,000 ft under UAV operating conditions.[7] The PD200 was specifically developed for maritime and ship-based UAV operations. According to TEI General Manager Prof. Dr. Mahmut F. Akşit, the engine incorporates marinization modifications and corrosion-resistant components for operation in saline naval environments.[8] TEI states that the engine was structurally and mechanically differentiated as a marine-adapted variant for ship-based operations and successfully completed salt fog tests in accordance with MIL-STD-810G Method 509.6 standards.[9]
